askprof@moawadskininstitute.com
• Concepts of beauty have
been continuously evolving
throughout the history of
humankind.
• Slimmer forms have
substituted the voluptuous
figure idealized by artists in
the past.
• With fashion promoting
body-revealing attire,
outdoor exposure, and the
emphasis on fitness and
good health, people have
sought to reflect these
trends by demonstrating
youthfulness and vitality in
their bodies.

• On the other hand, a
sedentary lifestyle and
dietary excesses associated
with factors such as
genetic determination,
pregnancy, and the aging
process contribute to body
alterations that result in
the loss of the individual’s
body image, creating a
solid psychological
motivation for surgical
correction.

• Localized fat deposits
may involve one
anatomical region and
extend to multiple body
regions.
• Therefore, it is
understandable that body
contouring surgery
includes most body
regions, including the
face, neck, and breast, in
all populations, be treated
by a one-stage operation
or require more complex
combined procedures.

Introduction
• The current evidence-building
process in the healthcare industry is
riddled with conflicts of interest
regarding education, research, and the
practice of medicine.
• Medical specialists worldwide are
flooded with data they must collect,
process, and analyze.
• Medical images make up around 90%
of the data in healthcare.
• Experts across the globe point to the
harms of pervasive industry influence
on research, practice, and education in
healthcare, noting that it compromises
patient care.
10/21/2022 email: askprof@moawadskininstitute.com 10
Introduction
• The ESCSL, as an academic, non-profit
organization, is responsible for disseminating
unbiased findings to the industry, medical
health providers, and the public about
liposuction, among others.
• At the same time, it is entirely free of ties with
the industry.
• As the president of ESCSL, I retrospectively
reviewed patients' charts and photos
(thousands) who underwent body contouring
and fat grafting procedures in K.S.A. and Egypt
between 2002 and 2022.
• The unbiased evidence in this study is a way to
ensure that the benefits and harms of
liposuction are accurately reported.
• It will guide members of ESCSL in delivering
high-quality, evidence-based medicine and
cost-effective surgery.
10/21/2022 email: askprof@moawadskininstitute.com 11
Introduction
• During the journey, I developed my technique as any other
medical provider; trial and error, reading and seeing experts'
techniques, and picking and choosing what suited me based on
science and skills.
10/21/2022 email: askprof@moawadskininstitute.com 12
Introduction
• The data collected are given to those who
want to deliver the best care to their
patients armed with the most innovative
techniques and the latest technology in the
battle of aging, rejuvenation, and body in a
safe outcome-driven manner.
• It also is given to novice(s) in professional
and educational standards.
• A compendium of the author’s practice,
journal publications, and books read will
allow the reader to enjoy the fruits of this
labor.
• This manual puts the entire liposuction
process in a volume that surgeons
interested in this topic need to read.
10/21/2022 email: askprof@moawadskininstitute.com 13
Introduction
• As new techniques are introduced, we must temper
our enthusiasm and base treatment on solid scientific
evidence.
• The journey is ongoing. It is like riding a bicycle; to
keep balance, you should keep moving.

Liposuction
Complications
and its Management
• Although many people view it as a simple and benign
procedure, it can be associated with significant
morbidity, especially large-volume liposuction.
• The ideal situation involves a selected patient treated
by a well-trained surgeon and anesthesiologist, the
team working in a fully equipped, certified, and
accredited facility with a well-trained operating room
and recovery room staff.
• Physicians should limit the lipoaspirate to less than 5%
of the body weight and treat less than 30% of the
body surface in one session.
10/21/2022 email: askprof@moawadskininstitute.com 15
Liposuction Complications and its Management
• Unfortunately, complications can vary from mild
postoperative nausea and vomiting to DVT/pulmonary
embolism (P.E.) and even death.
• The onset of complications can be classified into the
perioperative period (0–48 h), early postoperative period
(days 1–7), and late postoperative period (1 week to 3
months).
• Major risk factors for developing severe complications
are multiple procedures, poor standards of sterility,
excessive infiltration and intoxication from lidocaine or
adrenaline, excessive removal of fatty tissue with volume
depletion in the third space, permissive postoperative
discharge, and selection of unfit patients.
10/21/2022 email: askprof@moawadskininstitute.com 16
Life-threatening
Complications
• Hypothermia
• Lidocaine Anaphylaxis
• Lidocaine Toxicity
• Epinephrine Toxicity
• Pulmonary Edema
• Thromboembolism
• Pulmonary Embolism
• Fat Embolism Syndrome
• Perforation of Blood vessels
• Perforation of Internal Organ
• Bleeding and hemorrhages
• Infection
10/21/2022 email: askprof@moawadskininstitute.com 17
Hypothermia
• Hypothermia, a medical emergency, is defined
as a core body temperature of <30°C.
• Hypothermia predisposes to a hypercoagulable
state and potentially fatal cardiac
dysrhythmias.
• Its risk is amplified in more prominent volume
cases, where a greater surface area of the
patient is exposed at one time, and patients
are under anesthesia longer.
• Preventative measures include warming the
wetting solutions and prep, room temperature,
and using warming devices.
10/21/2022 email: askprof@moawadskininstitute.com 18
Lidocaine
Anaphylaxis
• Lidocaine is not a completely benign
medication.
• It has been associated with death from an
allergic reaction to the preservative
methylparaben.
• The surgeon should be aware of and prepared
for acute allergic reactions.
• Treatment with ephedrine, oxygenation, and
intravenous fluids can relieve the symptoms.
• Steroids may be necessary, and intubation may
have to be done if there is bronchospasm.
• Fortunately, I never encountered such a case.
10/21/2022 email: askprof@moawadskininstitute.com 19
Lidocaine Toxicity
• Lidocaine toxicity can easily be avoided by keeping the
lidocaine at a safe level through less than 35 mg/kg or,
when necessary, a maximum of 55 mg/kg in the total
tumescent fluid.
• I always inject slowly and in large volumes; I inject by
section.
• Be aware that the epinephrine effect causing vascular
contraction takes 15 minutes following injection; therefore,
the lidocaine can be rapidly absorbed for the first 15
minutes.
• The more rapid the lidocaine infiltration, the more likely
there will be lidocaine toxicity.
There is little treatment for lidocaine toxicity
except for supportive measures.
Medications inhibiting cytochrome oxidase P450 3A4
email:
askprof@moawadskininstitute.com
• A careful history must be taken to ensure
the patient has not been taking cytochrome
P450 inhibitors that may result in toxicity
even with the total lidocaine dose is within
the usually accepted maximum.
• Since, the peak of lidocaine absorption is 8
to 12 hours after injection do not discharge e
a patient too soon.
10/21/2022 21
Pulmonary
Edema
• Pulmonary edema can be caused by
overhydration after injection of too much
tumescent fluid, or intravenous fluids, or
both, with poor patient or drug
monitoring
• Preoperative medical clearance for any
patient with risk factors should be
obtained.
10/21/2022 email: askprof@moawadskininstitute.com 22
Pulmonary Embolism
• For the last 25 years, pulmonary embolism has been the leading
killer among patients who have undergone cosmetic surgery and
is responsible for one-fourth of unavoidable deaths.
• Pulmonary embolism is manifested by one of three clinical
patterns:
• Increased resistance or pain on voluntary dorsiflexion of the
foot (Homan's sign) and tenderness of the calf on palpation
are functional diagnostic criteria.
• The onset of sudden dyspnea with tachypnea and no other
symptoms
• Sudden pleuritic chest pain and dyspnea associated with
findings of pleural effusion or lung consolidation
• Sudden apprehension, chest discomfort, and dyspnea result
from corpulmonale and systemic hypotension.
10/21/2022 email: askprof@moawadskininstitute.com 23
Thromboembolism
• High-risk patients for thromboembolism are: Over 40
years, have a prior history of the thromboembolic
disorder, have surgery over one h, are obese, and have
postoperative immobilization, estrogen therapy, or a
combined procedure.
• The surgeon should take the necessary precautions
taken during the perioperative period. Intermittent
compression devices for legs, early mobilization, and low
molecular weight heparins can reduce the risk.
• Drug prevention for deep venous thrombosis is
Nadroparin, 7500 UI/d, or enoxaparin, 20 to 40 mg/d but
may increase bleeding.
10/21/2022 email: askprof@moawadskininstitute.com 24
Fat Embolism
Syndrome
• Fat embolism syndrome is rare after liposuction
and occurs only after lengthy, combined
procedures.
• Lengthy procedures increase the risk of
complications; the optimum length of surgery
should not exceed 3 hours.
• Procedures longer than 2 hours with the patient
in the same position require using compression
boots or drug prevention of deep venous
thrombosis.
10/21/2022 email: askprof@moawadskininstitute.com 25
Hemorrhages and
Internal Bleeding
10/21/2022
26
email:
askprof@moawadskininstitute.com
• Hemorrhages can be caused by
significant vessel perforation, coagulopathy,
or internal organ perforation.
• Bleeding may appear as bright red blood
from the incision site or bloody aspirate.
• Excessive liposuctioning in a single area
may cause bloody fluid to appear in the
tubing.
• The surgeon should warn not to continue
surgery in that area unless a further
tumescent solution is used.
Hemorrhages and
Internal Bleeding
10/21/2022
27
email:
askprof@moawadskininstitute.com
• Any history of bleeding problems with prior surgery or
the family should be appropriately investigated.
• Uncontrolled hypertension must be corrected.
• Medications that might affect platelet function or the
clotting cascade must be discontinued to allow
sufficient time to return to normal clotting.
• Compression over liposuction areas will help limit
bleeding.
• If the patient's clinical status and vital signs are stable,
conservative measures such as volume replacement
may be taken.
• Intravenous fluid resuscitation may be enough if the
bleeding is not over 15 % of the blood volume.
Hemorrhages and
Internal Bleeding
10/21/2022
28
email:
askprof@moawadskininstitute.com
• Significant internal bleeding presents as abdominal
pain, orthostatic hypotension, and shock.
• Postoperative dizziness and feeling faint should not be
considered a drug reaction or dehydration until after the
hemoglobin (Hgb), or the hematocrit (H.C.T.) is checked.
• Low Hgb or H.C.T. should be followed for several weeks.
• It may take a few weeks for the blood count to return to
normal, but usually, the patient can resume regular
activity after the Hgb reaches 8 g.
• However, some patients with more blood loss may
require dextran, albumin, or blood to restore the blood
volume.
• Surgical exploration may be necessary if the bleeding
continues, and conservative measures do not work.
• If the blood is retroperitoneal, a C.T. scan may be
required.
Perforation of the
Abdomen
• Internal organ perforation must be regarded if unusual
abdominal pain or chest pain occurs postoperatively.
• Perforation of the abdominal wall is most likely to
happen in the presence of a hernia or an abdominal wall
scar that can divert the direction of the cannula.
• Patient positioning might expose areas to undesired
trauma during suction lipectomy.
• The cannula type is another important consideration
since blunt cannulas are safer than small sharp ones.
• Care should be taken when using power-assisted
cannulas and even ultrasonic or laser technologies since
the tissue resistance changes make the penetration of
undesired structures easier.
10/21/2022 email: askprof@moawadskininstitute.com 29
Perforation of the Abdomen
• Liposuction must be performed with great caution and without
abrupt gestures.
• Liposuction must be tangential, with good orientation and
control of the depth of the cannula (on the other hand), without
ignoring the risk of intraperitoneal perforation.
• The surgeon should control the orientation of the cannula, which
must not be oriented deeply in the direction of the viscera.
• The non-dominant hand should always feel the end of the
cannula. When the cannula is not palpable, the surgeon should
reassess the technique and consider the possibility of perforation.
• The umbilicus should be avoided in patients with previous
abdominal surgery or a case of an abdominal scar. Instead, an
incision in the submammary or sub umbilical should be used. This
precaution will avoid passing through an umbilical hernia or a
diastasis of the median line.
10/21/2022 email: askprof@moawadskininstitute.com 30
Perforation of
the Abdomen
• It may be challenging to examine the
abdomen directly by pressure
because liposuction alone will cause
pain in the area.
• The presence of rebound tenderness
usually indicates peritonitis.
• A perforation can be sutured under
certain circumstances by a general
surgeon after rigorous exploration
and if the diagnosis is early enough.
10/21/2022 email: askprof@moawadskininstitute.com 31
Chest Perforation
• Severe chest pain, especially with dyspnea, may
indicate perforation in the chest.
• Chest X-ray will usually show a pneumothorax,
and insertion of a chest tube will relieve the pain
and dyspnea.
• Liposuction over the ribs can be aided using
pressure on the lower ribs with the flat portion of
the non-dominant hand, which will result in the
cannula quickly going over the ribs instead of under
with perforation into the chest.
10/21/2022 email: askprof@moawadskininstitute.com 32
Infection
• The occurrence of infection in a clean surgery case is approximately 1
% in outpatient surgery centers and 3 % in hospital surgeries.
• Liposuction's low infection rate is due to the combination of sterile
techniques, small incisions, and the antibacterial effects of lidocaine.
• Post-liposuction infection should be diagnosed as early as possible to
prevent serious complications.
• When infection occurs, patients exhibit signs of inflammation, micro-
abscesses, and purulent wound drainage.
• Microorganisms are isolated from the purulent drainage and
identified by routine microbiologic techniques.
• The most common organisms are typical skin flora, notably
Staphylococcus and Streptococcus.
• The community-acquired MRSA is often sensitive to trimethoprim-
sulfamethoxazole and Clindamycin.
10/21/2022 email: askprof@moawadskininstitute.com 33
Severe Infection
• Infection can be avoided with total antisepsis and proper antibiotics given. I
use I g of intravenous cephalosporin intraoperatively. The patient will
continue their antibiotics start one day before the surgery.
• It is essential that wounds be kept clean and that any change in the wound
site is reported to the physician immediately.
• Patients with severe pain or redness that does not improve with first-line
treatment should have the possibility of rare causes: necrotizing fasciitis, Toxic
shock syndrome, atypical mycobacterium, herpetic viral infections, or fungal
infections.
• Necrotizing fasciitis usually provokes widespread necrosis of the superficial
and deep fascia, which is associated with severe systemic toxic reactions.
• Mycobacterium should be considered when an infection appears ten days
to 6 weeks after surgery and is in the form of a mass with overlying redness
10/21/2022 email: askprof@moawadskininstitute.com 34
Toxic Shock Syndrome
Toxic shock syndrome presents as:
• Fever (above 102 °F)
• Rash (diffuse, macular erythroderma)
• Desquamation (1–2 weeks after onset, especially of palms and soles)
• Hypotension
• Negative results of the causative agent.
• Involvement of three or more organ systems:
I. Gastrointestinal (vomiting, diarrhea at onset)
II. Muscular (myalgia, elevated creatine phosphokinase)
III. Mucous membrane (conjunctiva, oropharynx)
IV. Renal (blood urea nitrogen or creatinine more than two times average)
V. Hepatic (bilirubin, SGPT, SGOT more than two times normal)
VI. Hematologic (fewer than 100,000 platelets)
10/21/2022 email: askprof@moawadskininstitute.com 35
Severe
Infections
• Severe infections require vigorous
prolonged treatment involving surgical
debridement, antibiotics, and circulatory
and respiratory care.
• Routine laboratory tests, contrast MRI,
and biopsy can help diagnose.
• Unfortunately, severe infections can lead
to significant scarring.
10/21/2022 email: askprof@moawadskininstitute.com 36
Aesthetic
Complications
• The increasing number of liposuction
procedures has led to a growing number of
iatrogenic fat tissue deformities, so the need
for corrective procedures has also increased.
• The most common aesthetic complications
are as follows: edema, ecchymosis, under-
correction, overcorrection, irregularities,
seroma, hematoma, cutaneous
hyperpigmentation, and liquefied fat.
• Keeping the preoperative photographs
visible during surgery can check what the
deformity looks like with the patient standing
10/21/2022 email: askprof@moawadskininstitute.com 37
Edema and
Bruises
• Postoperative edema and ecchymosis
occur to varying extents in all patients.
The degree of postoperative bruising
depends on the individual patient,
surgical technique, and postoperative
care.
• Any gentle, uniform skin compression
will constrict the interstices within the
collagen bundles of the dermis and
restrict the oozing or trickling of red
blood cells, decreasing or preventing
visible bruising.
10/21/2022 email: askprof@moawadskininstitute.com 38
Edema and
Bruises
• An infrequent occurrence, persistent edema in liposuction, can be
distressing to the patient. Prolonged edema can occur up to 3 months post-
surgery and is best treated with supportive care and lymphatic massage.
• Repeat liposuction (in an amount to break up the edematous tissues and
flatten the region) with the tumescent technique is usually helpful after several
months. Still, it must be followed by adequate compression dressings.
Seromas and
Hematoma
email:
askprof@moawadskininstitute.com
• The collection of serous fluid in the liposuction area may be due to irritation of the
tissues by the traumatic procedure but is more frequently the result of concomitant over-
suctioning of a single site with undermining of a flap allowing a cavity to form.
• Most postoperative hematomas occur within the first 24 h.
• Sometimes a hematoma may appear first and be replaced over time with
serosanguinous fluid and then serous fluid.

Seroma
Seromas and
Hematoma
email:
askprof@moawadskininstitute.com
• A loose closure of cannula sites, postoperative
compression garments, and expression of residual fluid
over liposuction areas at the end of the procedure can
reduce the incidence of seroma formation.
• A persistent fluid collection following liposuction may
be treated with needle aspiration followed by adequate
compression dressings.
• Repeated aspiration is repeated every few days.
• If the collection becomes chronic (over four weeks), the
fluid should be aspirated, and an equal amount of room
air injected into the cavity to irritate.
10/21/2022 41
Seroma
Hyperpigmented Scars
• Hyperpigmentation following liposuction can be
in the scars or the area of the liposuction.
• Incision sites may be irritated by the multiple
fast passes of the cannula resulting in a reddening
around or incision site that can lead to a
hyperpigmented scar.
• Access sites should be wider than the cannula's
diameter, and the surgeon should place accessory
sites as needed.
• The hyperpigmented scar is treated as post-
inflammatory hyperpigmentation.
• Treatment consists of 4 % hydroquinone, cream,
or gel, rubbed into the affected area twice daily.
• Recently, I routinely rubbed all access sited with
fat extracted; the results are fantastic.
• During the day, an effective sunscreen should
be utilized, unnecessary sun exposure must be
avoided, or protective clothing must be worn.
10/21/2022 email: askprof@moawadskininstitute.com 42
Asymmetry
10/21/2022
43
email:
askprof@moawadskininstitute.com
• Photographing is of utmost importance as a
guide for the surgeon during the surgery and
postoperative comparison.
• Some patients forget what they looked like
before surgery.
• Many patients with scoliosis have a
deformity in the dorsal region that causes the
accumulation of fat more on one side than the
other.
• They usually only note this difference after
the procedure.
• The difference can be seen when you show
them similar before-and-after pictures side by
side.
Asymmetry
10/21/2022
44
email:
askprof@moawadskininstitute.com
• Asymmetry can be corrected by
removing more fat from the excess,
liposhifting fat into the depressed area, or
re-injecting autologous fat.
• Asymmetry can be avoided by being
aware of the amounts of fat and fluid
removed from each side so that there is no
large discrepancy.
• Observing the results at the end of
liposuction may disclose further areas that
need correction.
Loose Skin
• Loose skin after liposuction results from
excessive fat removal beyond the innate ability
to adequately retract or be redraped.
• Loose skin problems occur more in:
• Abdomen: especially with large
panniculus.
• Arms: especially elderly patients and
obese patients.
• Medial thighs: postoperative loose skin
is a significant problem in many
patients.
• Treatment for loose skin requires a
surgical approach with substantial
scars.

Contour Deformities
email: askprof@moawadskininstitute.com
• The increasing number of
liposuction procedures has
led to a growing number of
iatrogenic fat tissue
deformities).
• Liposuction sequelae can
result from under-
correction (insufficient fat
removal,) overcorrection
(excessive fat reduction),
and irregular fat removal
(with noticeable and visible
irregularities.).
10/21/2022 46
Contour Deformities
• Treatment consists in freeing the fibrous adherences, aspirating fat from the high areas, and injecting fat
into the depression and fat shifting.
• Using small cannulas, not performing superficial liposuction, turning the suction off when exiting
incisions, crisscrossing areas, constantly analyzing areas (visual and tactile), and proper positioning can all
help reduce the chance of contour irregularities.
10/21/2022 email: askprof@moawadskininstitute.com 47
Nodularity, Fibrosis,
and Scaring
• Infection, especially mycobacterial, can
leave a mass that will not resolve.
• Subcutaneous nodularity following
liposuction (residual hematoma or
seroma) is often associated with an
inflammatory component that might end
in fibrosis or scarring.
• Folds in the garment can result in
indentations and subcutaneous fibrosis.
10/21/2022 email: askprof@moawadskininstitute.com 48
Nodularity,
Fibrosis or Scar
• Energy-dependent liposuction produces
tissue trauma that might result in internal
fibrosis, skin, and scarring.
• Hypertrophic or keloid scars treatment
includes steroid injection, re-excision,
silicone gel sheeting, pressure therapy, or
a combination.
10/21/2022 email: askprof@moawadskininstitute.com 49
Medial Thigh
Nodularity, Fibrosis, and
Scaring
email: askprof@moawadskininstitute.com
• The garment should be checked on
the first postoperative day, and the
patient should be informed of how to
prevent or limit folds in the garment
(especially an abdominal binder).
• Initial treatment will resolve the
complication faster than waiting for
the fibrosis to mature into a scar.
• The conservative course of treatment
for residual fibrosis from any source
consists of the following:
I. I give long-acting steroids 40mg
I.M. single dose for patient
compliance
II. I use monopolar radiofrequency
started at least three weeks after
surgery for one session /week for
3-6 treatments.
III. I inject a mixture of 0.5mL
verapamil, 0.5 mL triamcinolone,
and 1 mL lidocaine.

Neurovascular
Complications
• An abnormal, increased sensitivity or
decreased sensation are common
sequelae of liposuction, which will
gradually improve three to six months
after surgery.
• Acute median nerve compression has
been reported from administering large
amounts of intravenous fluids during
liposuction—the edematous nerve
compression resolved with an elevation
of the extremities and diuretics.
• Chronic pain may be due to a small
neuroma that can be removed surgically.
10/21/2022 email: askprof@moawadskininstitute.com 51
Neurovascular
Complications
• Erythema ab lipoaspiration is persistent, reticulated
erythema, as a result of excessive superficial liposuction.
• Unfortunately, no treatment exists for this chronic
reticulated erythema, and it does not seem to improve
with time.
• Venous areas in the ankles and calves may persist for
six months or a year.
• Proper compression is usually the key to prevention.
• Remember that excessive extremity compression can
result in venous thrombosis and possible embolic
disorder.
10/21/2022 email: askprof@moawadskininstitute.com 52
Neurovascular
Complications
• Skin necrosis is more likely to occur
with cannulas with sharp edges and
turning the openings toward the skin
surface disrupting the subdermal
plexus of vessels.
• Chronic smokers who do not stop
smoking before and after surgery have
a high incidence of necrosis.
10/21/2022 email: askprof@moawadskininstitute.com 53
Neurovascular
Complications
• Two patients were treated by U-PAL in
the axilla for hyperhidrosis, one
developed a purpuric skin rash on one
side associated with hematoma.
• The patient was treated conservatively.
10/21/2022 email: askprof@moawadskininstitute.com 54
Neurovascular
Complications
• The other patient developed a more
severe reaction with oozing (vasculitis-like
rash) on both arms with skin necrosis in
both axillae.
• Skin necrosis progressed to full-
thickness ulceration and ended in axilla
scarring.
• Both patients were done by a novice
plastic surgeon.

Liposuction
Caveat
1. Ensure proper patient selection.
2. Obtain preoperative examinations of the
patient, including photographs, weight and
measurements records, and informed

Liposuction
Caveat
• 14. Supply postoperative dressing and girdles with adequate compression.
• 15. Provide monitoring devices for patients in an outpatient setting (i.e., pulse
oximeters, disconnect alarms, continuous cardiac monitoring devices).
• 16. Provide adequate patient surveillance.
• 17. Schedule a postoperative visit (on the day of and the first day after surgery).

Where to start? 59
For novice (s) who want to acquire the surgical skill of liposuction but do not know
where:
• Start doing fat grafting as a first step.
• Your cost will be minimum (a 10 ml Luer lock syringes and a few microcannulas).
• You will learn how to respect the fat (extracted) and the fat (left).
• As you move on, you will learn the skill of precision, whether you are extracting or injecting fat .
• Syringe reduction liposuction is the starting point.
• The most powerful fat melting energy is your energy (exertion) with the help of mechanical hydrodissection of
infiltrating tumescent anesthesia.
• Any extra energy added will indiscreetly damage the delicate nature of adipose tissue.

Conclusion
• The goal of liposuction is the reduction of localized fatty tissue to produce well-proportioned
body contours.
• The development of liposuction provided cosmetic surgeons with a safe and effective way to
sculpt the human figure.
• It brings as much contentment and joy to the person undergoing it as to the surgeon.
• Liposuction is more of an art than a surgical procedure; it entails a practical application of
scientific knowledge with precision and craftsmanship that attained with clinical experience.

• Although liposuction has
been considered a safe
surgical procedure for the last
30 years, to avoid
complications, one should be
mindful of all the factors that
could predispose them.
THE END
• This chapter, a unique educational manual, is dedicated to dermatologists
and cosmetic surgeons who want to excel in delivering the best care and
liposuction results to their patients with the most innovative techniques
and latest technology in a safe outcome-driven manner.
• I have assembled my experience and global experts to inform you how
liposuction is done in a simplified, efficient, and reproducible manner.
• Liposuction is more of an art than a surgical procedure.
• It entails a practical application of scientific knowledge with precision and
craftsmanship and is a skill attained with clinical experience.
• It brings as much contentment and joy to the person undergoing it as to
the surgeon practicing.

Liposuction Complications and its Management.pptx

  • 1. From Adding (1997) to Removing Fat (2022): Evidence Based Practice By Prof. Osama B. Moawad, M.Sc. M.D. 10/21/2022 email: askprof@moawadskininstitute.com 1
  • 2. Dedication The Journey of Liposuction 10/21/2022 email: askprof@moawadskininstitute.com 2 • This presentation is dedicated to the memory of my parents, Prof. M. Moawad, and my mother, Iqbal S. They made me what I am today with encouragement and sacrifices. • To my family, my wife Salam. B., and my pride in life, my son Mo and my daughter Noor with their unflagging support, turned the second part of my life journey into success.
  • 3. The Journey of Liposuction • Special acknowledgment is given to Dr. Ibrahim El Dousky (M.D., IMRCS), not only because he is an outstanding student but also because he doomed me into the life of plastic surgery with his excellent work and experience. • Dr. El Dousky is the general secretary of ESCSL. 10/21/2022 email: askprof@moawadskininstitute.com 3
  • 4. Acknowledgment • Special acknowledgment is given to Dr. M. Ramadan (MS., Ph.D.), a brilliant scientist, chief of staff at MSI and my right hand in all what I do. • Dr. Ramadan is on the board of directors of ESCSL. 11/4/2022 email: askprof@moawadskininstitute.com 4
  • 5. The Journey of Liposuction • The author would like to express his appreciation to the medical team at L'institute (Riyadh, KSA) and Moawad Skin Institute (MSI) in Cairo, Egypt, for taking care of the patient during the procedures. 10/21/2022 email: askprof@moawadskininstitute.com 5
  • 6. The Journey of Liposuction • To “PATIENTS” You’ve always believed in me KEYWORDS: LIPOSUCTION., LIPOSCULPTURE., FAT GRAFTING, ADIPOSE FATTY TISSUES., BODY CONTOURING. 10/21/2022 email: askprof@moawadskininstitute.com 6
  • 7. Introduction email: askprof@moawadskininstitute.com • Concepts of beauty have been continuously evolving throughout the history of humankind. • Slimmer forms have substituted the voluptuous figure idealized by artists in the past. • With fashion promoting body-revealing attire, outdoor exposure, and the emphasis on fitness and good health, people have sought to reflect these trends by demonstrating youthfulness and vitality in their bodies. 10/21/2022 7
  • 8. Introduction email: askprof@moawadskininstitute.com • On the other hand, a sedentary lifestyle and dietary excesses associated with factors such as genetic determination, pregnancy, and the aging process contribute to body alterations that result in the loss of the individual’s body image, creating a solid psychological motivation for surgical correction. 10/21/2022 8
  • 9. Introduction email: askprof@moawadskininstitute.com • Localized fat deposits may involve one anatomical region and extend to multiple body regions. • Therefore, it is understandable that body contouring surgery includes most body regions, including the face, neck, and breast, in all populations, be treated by a one-stage operation or require more complex combined procedures. 10/21/2022 9
  • 10. Introduction • The current evidence-building process in the healthcare industry is riddled with conflicts of interest regarding education, research, and the practice of medicine. • Medical specialists worldwide are flooded with data they must collect, process, and analyze. • Medical images make up around 90% of the data in healthcare. • Experts across the globe point to the harms of pervasive industry influence on research, practice, and education in healthcare, noting that it compromises patient care. 10/21/2022 email: askprof@moawadskininstitute.com 10
  • 11. Introduction • The ESCSL, as an academic, non-profit organization, is responsible for disseminating unbiased findings to the industry, medical health providers, and the public about liposuction, among others. • At the same time, it is entirely free of ties with the industry. • As the president of ESCSL, I retrospectively reviewed patients' charts and photos (thousands) who underwent body contouring and fat grafting procedures in K.S.A. and Egypt between 2002 and 2022. • The unbiased evidence in this study is a way to ensure that the benefits and harms of liposuction are accurately reported. • It will guide members of ESCSL in delivering high-quality, evidence-based medicine and cost-effective surgery. 10/21/2022 email: askprof@moawadskininstitute.com 11
  • 12. Introduction • During the journey, I developed my technique as any other medical provider; trial and error, reading and seeing experts' techniques, and picking and choosing what suited me based on science and skills. 10/21/2022 email: askprof@moawadskininstitute.com 12
  • 13. Introduction • The data collected are given to those who want to deliver the best care to their patients armed with the most innovative techniques and the latest technology in the battle of aging, rejuvenation, and body in a safe outcome-driven manner. • It also is given to novice(s) in professional and educational standards. • A compendium of the author’s practice, journal publications, and books read will allow the reader to enjoy the fruits of this labor. • This manual puts the entire liposuction process in a volume that surgeons interested in this topic need to read. 10/21/2022 email: askprof@moawadskininstitute.com 13
  • 14. Introduction • As new techniques are introduced, we must temper our enthusiasm and base treatment on solid scientific evidence. • The journey is ongoing. It is like riding a bicycle; to keep balance, you should keep moving. 10/21/2022 email: askprof@moawadskininstitute.com 14 2021 2022
  • 15. Liposuction Complications and its Management • Although many people view it as a simple and benign procedure, it can be associated with significant morbidity, especially large-volume liposuction. • The ideal situation involves a selected patient treated by a well-trained surgeon and anesthesiologist, the team working in a fully equipped, certified, and accredited facility with a well-trained operating room and recovery room staff. • Physicians should limit the lipoaspirate to less than 5% of the body weight and treat less than 30% of the body surface in one session. 10/21/2022 email: askprof@moawadskininstitute.com 15
  • 16. Liposuction Complications and its Management • Unfortunately, complications can vary from mild postoperative nausea and vomiting to DVT/pulmonary embolism (P.E.) and even death. • The onset of complications can be classified into the perioperative period (0–48 h), early postoperative period (days 1–7), and late postoperative period (1 week to 3 months). • Major risk factors for developing severe complications are multiple procedures, poor standards of sterility, excessive infiltration and intoxication from lidocaine or adrenaline, excessive removal of fatty tissue with volume depletion in the third space, permissive postoperative discharge, and selection of unfit patients. 10/21/2022 email: askprof@moawadskininstitute.com 16
  • 17. Life-threatening Complications • Hypothermia • Lidocaine Anaphylaxis • Lidocaine Toxicity • Epinephrine Toxicity • Pulmonary Edema • Thromboembolism • Pulmonary Embolism • Fat Embolism Syndrome • Perforation of Blood vessels • Perforation of Internal Organ • Bleeding and hemorrhages • Infection 10/21/2022 email: askprof@moawadskininstitute.com 17
  • 18. Hypothermia • Hypothermia, a medical emergency, is defined as a core body temperature of <30°C. • Hypothermia predisposes to a hypercoagulable state and potentially fatal cardiac dysrhythmias. • Its risk is amplified in more prominent volume cases, where a greater surface area of the patient is exposed at one time, and patients are under anesthesia longer. • Preventative measures include warming the wetting solutions and prep, room temperature, and using warming devices. 10/21/2022 email: askprof@moawadskininstitute.com 18
  • 19. Lidocaine Anaphylaxis • Lidocaine is not a completely benign medication. • It has been associated with death from an allergic reaction to the preservative methylparaben. • The surgeon should be aware of and prepared for acute allergic reactions. • Treatment with ephedrine, oxygenation, and intravenous fluids can relieve the symptoms. • Steroids may be necessary, and intubation may have to be done if there is bronchospasm. • Fortunately, I never encountered such a case. 10/21/2022 email: askprof@moawadskininstitute.com 19
  • 20. Lidocaine Toxicity • Lidocaine toxicity can easily be avoided by keeping the lidocaine at a safe level through less than 35 mg/kg or, when necessary, a maximum of 55 mg/kg in the total tumescent fluid. • I always inject slowly and in large volumes; I inject by section. • Be aware that the epinephrine effect causing vascular contraction takes 15 minutes following injection; therefore, the lidocaine can be rapidly absorbed for the first 15 minutes. • The more rapid the lidocaine infiltration, the more likely there will be lidocaine toxicity. There is little treatment for lidocaine toxicity except for supportive measures.
  • 21. Medications inhibiting cytochrome oxidase P450 3A4 email: askprof@moawadskininstitute.com • A careful history must be taken to ensure the patient has not been taking cytochrome P450 inhibitors that may result in toxicity even with the total lidocaine dose is within the usually accepted maximum. • Since, the peak of lidocaine absorption is 8 to 12 hours after injection do not discharge e a patient too soon. 10/21/2022 21
  • 22. Pulmonary Edema • Pulmonary edema can be caused by overhydration after injection of too much tumescent fluid, or intravenous fluids, or both, with poor patient or drug monitoring • Preoperative medical clearance for any patient with risk factors should be obtained. 10/21/2022 email: askprof@moawadskininstitute.com 22
  • 23. Pulmonary Embolism • For the last 25 years, pulmonary embolism has been the leading killer among patients who have undergone cosmetic surgery and is responsible for one-fourth of unavoidable deaths. • Pulmonary embolism is manifested by one of three clinical patterns: • Increased resistance or pain on voluntary dorsiflexion of the foot (Homan's sign) and tenderness of the calf on palpation are functional diagnostic criteria. • The onset of sudden dyspnea with tachypnea and no other symptoms • Sudden pleuritic chest pain and dyspnea associated with findings of pleural effusion or lung consolidation • Sudden apprehension, chest discomfort, and dyspnea result from corpulmonale and systemic hypotension. 10/21/2022 email: askprof@moawadskininstitute.com 23
  • 24. Thromboembolism • High-risk patients for thromboembolism are: Over 40 years, have a prior history of the thromboembolic disorder, have surgery over one h, are obese, and have postoperative immobilization, estrogen therapy, or a combined procedure. • The surgeon should take the necessary precautions taken during the perioperative period. Intermittent compression devices for legs, early mobilization, and low molecular weight heparins can reduce the risk. • Drug prevention for deep venous thrombosis is Nadroparin, 7500 UI/d, or enoxaparin, 20 to 40 mg/d but may increase bleeding. 10/21/2022 email: askprof@moawadskininstitute.com 24
  • 25. Fat Embolism Syndrome • Fat embolism syndrome is rare after liposuction and occurs only after lengthy, combined procedures. • Lengthy procedures increase the risk of complications; the optimum length of surgery should not exceed 3 hours. • Procedures longer than 2 hours with the patient in the same position require using compression boots or drug prevention of deep venous thrombosis. 10/21/2022 email: askprof@moawadskininstitute.com 25
  • 26. Hemorrhages and Internal Bleeding 10/21/2022 26 email: askprof@moawadskininstitute.com • Hemorrhages can be caused by significant vessel perforation, coagulopathy, or internal organ perforation. • Bleeding may appear as bright red blood from the incision site or bloody aspirate. • Excessive liposuctioning in a single area may cause bloody fluid to appear in the tubing. • The surgeon should warn not to continue surgery in that area unless a further tumescent solution is used.
  • 27. Hemorrhages and Internal Bleeding 10/21/2022 27 email: askprof@moawadskininstitute.com • Any history of bleeding problems with prior surgery or the family should be appropriately investigated. • Uncontrolled hypertension must be corrected. • Medications that might affect platelet function or the clotting cascade must be discontinued to allow sufficient time to return to normal clotting. • Compression over liposuction areas will help limit bleeding. • If the patient's clinical status and vital signs are stable, conservative measures such as volume replacement may be taken. • Intravenous fluid resuscitation may be enough if the bleeding is not over 15 % of the blood volume.
  • 28. Hemorrhages and Internal Bleeding 10/21/2022 28 email: askprof@moawadskininstitute.com • Significant internal bleeding presents as abdominal pain, orthostatic hypotension, and shock. • Postoperative dizziness and feeling faint should not be considered a drug reaction or dehydration until after the hemoglobin (Hgb), or the hematocrit (H.C.T.) is checked. • Low Hgb or H.C.T. should be followed for several weeks. • It may take a few weeks for the blood count to return to normal, but usually, the patient can resume regular activity after the Hgb reaches 8 g. • However, some patients with more blood loss may require dextran, albumin, or blood to restore the blood volume. • Surgical exploration may be necessary if the bleeding continues, and conservative measures do not work. • If the blood is retroperitoneal, a C.T. scan may be required.
  • 29. Perforation of the Abdomen • Internal organ perforation must be regarded if unusual abdominal pain or chest pain occurs postoperatively. • Perforation of the abdominal wall is most likely to happen in the presence of a hernia or an abdominal wall scar that can divert the direction of the cannula. • Patient positioning might expose areas to undesired trauma during suction lipectomy. • The cannula type is another important consideration since blunt cannulas are safer than small sharp ones. • Care should be taken when using power-assisted cannulas and even ultrasonic or laser technologies since the tissue resistance changes make the penetration of undesired structures easier. 10/21/2022 email: askprof@moawadskininstitute.com 29
  • 30. Perforation of the Abdomen • Liposuction must be performed with great caution and without abrupt gestures. • Liposuction must be tangential, with good orientation and control of the depth of the cannula (on the other hand), without ignoring the risk of intraperitoneal perforation. • The surgeon should control the orientation of the cannula, which must not be oriented deeply in the direction of the viscera. • The non-dominant hand should always feel the end of the cannula. When the cannula is not palpable, the surgeon should reassess the technique and consider the possibility of perforation. • The umbilicus should be avoided in patients with previous abdominal surgery or a case of an abdominal scar. Instead, an incision in the submammary or sub umbilical should be used. This precaution will avoid passing through an umbilical hernia or a diastasis of the median line. 10/21/2022 email: askprof@moawadskininstitute.com 30
  • 31. Perforation of the Abdomen • It may be challenging to examine the abdomen directly by pressure because liposuction alone will cause pain in the area. • The presence of rebound tenderness usually indicates peritonitis. • A perforation can be sutured under certain circumstances by a general surgeon after rigorous exploration and if the diagnosis is early enough. 10/21/2022 email: askprof@moawadskininstitute.com 31
  • 32. Chest Perforation • Severe chest pain, especially with dyspnea, may indicate perforation in the chest. • Chest X-ray will usually show a pneumothorax, and insertion of a chest tube will relieve the pain and dyspnea. • Liposuction over the ribs can be aided using pressure on the lower ribs with the flat portion of the non-dominant hand, which will result in the cannula quickly going over the ribs instead of under with perforation into the chest. 10/21/2022 email: askprof@moawadskininstitute.com 32
  • 33. Infection • The occurrence of infection in a clean surgery case is approximately 1 % in outpatient surgery centers and 3 % in hospital surgeries. • Liposuction's low infection rate is due to the combination of sterile techniques, small incisions, and the antibacterial effects of lidocaine. • Post-liposuction infection should be diagnosed as early as possible to prevent serious complications. • When infection occurs, patients exhibit signs of inflammation, micro- abscesses, and purulent wound drainage. • Microorganisms are isolated from the purulent drainage and identified by routine microbiologic techniques. • The most common organisms are typical skin flora, notably Staphylococcus and Streptococcus. • The community-acquired MRSA is often sensitive to trimethoprim- sulfamethoxazole and Clindamycin. 10/21/2022 email: askprof@moawadskininstitute.com 33
  • 34. Severe Infection • Infection can be avoided with total antisepsis and proper antibiotics given. I use I g of intravenous cephalosporin intraoperatively. The patient will continue their antibiotics start one day before the surgery. • It is essential that wounds be kept clean and that any change in the wound site is reported to the physician immediately. • Patients with severe pain or redness that does not improve with first-line treatment should have the possibility of rare causes: necrotizing fasciitis, Toxic shock syndrome, atypical mycobacterium, herpetic viral infections, or fungal infections. • Necrotizing fasciitis usually provokes widespread necrosis of the superficial and deep fascia, which is associated with severe systemic toxic reactions. • Mycobacterium should be considered when an infection appears ten days to 6 weeks after surgery and is in the form of a mass with overlying redness 10/21/2022 email: askprof@moawadskininstitute.com 34
  • 35. Toxic Shock Syndrome Toxic shock syndrome presents as: • Fever (above 102 °F) • Rash (diffuse, macular erythroderma) • Desquamation (1–2 weeks after onset, especially of palms and soles) • Hypotension • Negative results of the causative agent. • Involvement of three or more organ systems: I. Gastrointestinal (vomiting, diarrhea at onset) II. Muscular (myalgia, elevated creatine phosphokinase) III. Mucous membrane (conjunctiva, oropharynx) IV. Renal (blood urea nitrogen or creatinine more than two times average) V. Hepatic (bilirubin, SGPT, SGOT more than two times normal) VI. Hematologic (fewer than 100,000 platelets) 10/21/2022 email: askprof@moawadskininstitute.com 35
  • 36. Severe Infections • Severe infections require vigorous prolonged treatment involving surgical debridement, antibiotics, and circulatory and respiratory care. • Routine laboratory tests, contrast MRI, and biopsy can help diagnose. • Unfortunately, severe infections can lead to significant scarring. 10/21/2022 email: askprof@moawadskininstitute.com 36
  • 37. Aesthetic Complications • The increasing number of liposuction procedures has led to a growing number of iatrogenic fat tissue deformities, so the need for corrective procedures has also increased. • The most common aesthetic complications are as follows: edema, ecchymosis, under- correction, overcorrection, irregularities, seroma, hematoma, cutaneous hyperpigmentation, and liquefied fat. • Keeping the preoperative photographs visible during surgery can check what the deformity looks like with the patient standing 10/21/2022 email: askprof@moawadskininstitute.com 37
  • 38. Edema and Bruises • Postoperative edema and ecchymosis occur to varying extents in all patients. The degree of postoperative bruising depends on the individual patient, surgical technique, and postoperative care. • Any gentle, uniform skin compression will constrict the interstices within the collagen bundles of the dermis and restrict the oozing or trickling of red blood cells, decreasing or preventing visible bruising. 10/21/2022 email: askprof@moawadskininstitute.com 38
  • 39. Edema and Bruises • An infrequent occurrence, persistent edema in liposuction, can be distressing to the patient. Prolonged edema can occur up to 3 months post- surgery and is best treated with supportive care and lymphatic massage. • Repeat liposuction (in an amount to break up the edematous tissues and flatten the region) with the tumescent technique is usually helpful after several months. Still, it must be followed by adequate compression dressings.
  • 40. Seromas and Hematoma email: askprof@moawadskininstitute.com • The collection of serous fluid in the liposuction area may be due to irritation of the tissues by the traumatic procedure but is more frequently the result of concomitant over- suctioning of a single site with undermining of a flap allowing a cavity to form. • Most postoperative hematomas occur within the first 24 h. • Sometimes a hematoma may appear first and be replaced over time with serosanguinous fluid and then serous fluid. 10/21/2022 40 Next Day Follow up Visit Few Days Later Seroma
  • 41. Seromas and Hematoma email: askprof@moawadskininstitute.com • A loose closure of cannula sites, postoperative compression garments, and expression of residual fluid over liposuction areas at the end of the procedure can reduce the incidence of seroma formation. • A persistent fluid collection following liposuction may be treated with needle aspiration followed by adequate compression dressings. • Repeated aspiration is repeated every few days. • If the collection becomes chronic (over four weeks), the fluid should be aspirated, and an equal amount of room air injected into the cavity to irritate. 10/21/2022 41 Seroma
  • 42. Hyperpigmented Scars • Hyperpigmentation following liposuction can be in the scars or the area of the liposuction. • Incision sites may be irritated by the multiple fast passes of the cannula resulting in a reddening around or incision site that can lead to a hyperpigmented scar. • Access sites should be wider than the cannula's diameter, and the surgeon should place accessory sites as needed. • The hyperpigmented scar is treated as post- inflammatory hyperpigmentation. • Treatment consists of 4 % hydroquinone, cream, or gel, rubbed into the affected area twice daily. • Recently, I routinely rubbed all access sited with fat extracted; the results are fantastic. • During the day, an effective sunscreen should be utilized, unnecessary sun exposure must be avoided, or protective clothing must be worn. 10/21/2022 email: askprof@moawadskininstitute.com 42
  • 43.

  • 44.

Editor's Notes

  1. From Adding (1997) to Removing Fat (2022): The Journey of Liposuction by Professor Osama B. Moawad. MSc., M.D.
  2. Dedications This presentation is dedicated to the memory of my parents, Prof. M.B. Moawad, and My mother, Iqbal S. They made me what I am today with encouragement and sacrifices. To my family, my wife Salam. B., and my pride in life, my son Mo and my Daughter Noor with their unflagging support, turned the second part of my life journey into success.
  3. The Journey of Liposuction Special acknowledgment is given to Dr. Ibrahim El Dousky (M.D., IMRCS), not only because he is an outstanding student but also because he doomed me into the life of plastic surgery with his excellent work and experience. Dr. El Dousky is the general secretary of ESCSL.
  4. Acknowledgment Special acknowledgment is given to Dr. M. Ramadan (MS., Ph.D.), a brilliant scientist, chief of staff at MSI and my right hand in all what I do. Dr. Ramadan is on the board of directors of ESCSL.
  5. The Journey of Liposuction The author would like to express their appreciation to the medical team at L'institute (Riyadh, KSA) and Moawad Skin Institute (MSI) in Cairo, Egypt, for taking care of the patient during the procedures.
  6. The Journey of Liposuction To “PATIENTS” You’ve always believed in me KEYWORDS: LIPOSUCTION., LIPOSCULPTURE., FAT GRAFTING, ADIPOSE FATTY TISSUES., BODY CONTOURING
  7. Introduction Concepts of beauty have been continuously evolving throughout the history of humankind. Slimmer forms have substituted the voluptuous figure idealized by artists in the past. With fashion promoting body-revealing attire, outdoor exposure, and the emphasis on fitness and good health, people have sought to reflect these trends by demonstrating youthfulness and vitality in their bodies.
  8. Introduction On the other hand, a sedentary lifestyle and dietary excesses associated with factors such as genetic determination, pregnancy, and the aging process contribute to body alterations that result in the loss of the individual’s body image, creating a solid psychological motivation for surgical correction
  9. Introduction Localized fat deposits may involve one anatomical region and extend to multiple body regions. Therefore, it is understandable that body contouring surgery includes most body regions, including the face, neck, and breast, in all populations, be treated by a one-stage operation or require more complex combined procedures
  10. Introduction The current evidence-building process in the healthcare industry is riddled with conflicts of interest regarding education, research, and the practice of medicine. Medical specialists worldwide are flooded with data they must collect, process, and analyze. Medical images make up around 90% of the data in healthcare. Experts across the globe point to the harms of pervasive industry influence on research, practice, and education in healthcare, noting that it compromises patient care.
  11. Introduction The ESCSL, as an academic, non-profit organization, is responsible for disseminating unbiased findings to the industry, medical health providers, and the public about liposuction, among others. At the same time, it is entirely free of ties with the industry. As the president of ESCSL, I retrospectively reviewed patients' charts and photos (thousands) who underwent body contouring and fat grafting procedures in K.S.A. and Egypt between 2002 and 2022. The unbiased evidence in this study is a way to ensure that the benefits and harms of liposuction are accurately reported. It will guide members of ESCSL in delivering high-quality, evidence-based medicine and cost-effective surgery.
  12. Introduction During the journey, I developed my technique as any other medical provider; trial and error, reading and seeing experts' techniques, and picking and choosing what suited me based on science and skills.
  13. Introduction The data collected are given to those who want to deliver the best care to their patients armed with the most innovative techniques and the latest technology in the battle of aging, rejuvenation, and body in a safe outcome-driven manner. It also is given to novice(s) in professional and educational standards. A compendium of the author’s practice, journal publications, and books read will allow the reader to enjoy the fruits of this labor. This manual puts the entire liposuction process in a volume that surgeons interested in this topic need to read.
  14. Introduction As new techniques are introduced, we must temper our enthusiasm and base treatment on solid scientific evidence. The journey is ongoing. It is like riding a bicycle; to keep balance, you should keep moving
  15. Liposuction Complications and its Management Although many people view it as a simple and benign procedure, it can be associated with significant morbidity, especially large-volume liposuction. The ideal situation involves a selected patient treated by a well-trained surgeon and anesthesiologist, the team working in a fully equipped, certified, and accredited facility with a well-trained operating room and recovery room staff. It should be performed by appropriately trained physicians who limit the lipoaspirate to less than 5% of the body weight and treat less than 30% of the body surface in one session.
  16. Liposuction Complications and its Management Unfortunately, complications can vary from mild postoperative nausea and vomiting to DVT/pulmonary embolism (P.E.) and even death. The onset of complications can be classified into the perioperative period (0–48 h), early postoperative period (days 1–7), and late postoperative period (1 week to 3 months). Major risk factors for developing severe complications are multiple procedures, poor standards of sterility, excessive infiltration and intoxication from lidocaine or adrenaline, excessive removal of fatty tissue with volume depletion in the third space, permissive postoperative discharge, and selection of unfit patients.
  17. Life-threatening Complications Hypothermia Lidocaine Anaphylaxis Lidocaine Toxicity Epinephrine Toxicity Pulmonary Edema Thromboembolism Pulmonary Embolism Fat Embolism Syndrome Perforation of Blood vessels Perforation of Internal Organ Bleeding and hemorrhages Infection
  18. Hypothermia Hypothermia, a medical emergency, is defined as a core body temperature of <30°C. Hypothermia predisposes to a hypercoagulable state and potentially fatal cardiac dysrhythmias. Its risk is amplified in more prominent volume cases, where a greater surface area of the patient is exposed at one time, and patients are under anesthesia longer. Preventative measures include warming the wetting solutions and prep, room temperature, and using warming devices.
  19. Lidocaine Anaphylaxis Lidocaine is not a completely benign medication. It has been associated with death from an allergic reaction to the preservative methylparaben. The surgeon should be aware of and prepared for acute allergic reactions. Treatment with ephedrine, oxygenation, and intravenous fluids can relieve the symptoms. Steroids may be necessary, and intubation may have to be done if there is bronchospasm. Fortunately, I never encountered such a case.
  20. Lidocaine Toxicity Lidocaine toxicity can easily be avoided by keeping the lidocaine at a safe level through less than 35 mg/kg or, when necessary, a maximum of 55 mg/kg in the total tumescent fluid. I always inject slowly and in large volumes; I inject by section. Be aware that the epinephrine effect causing vascular contraction takes 15 minutes following injection; therefore, the lidocaine can be rapidly absorbed for the first 15 minutes. The more rapid the lidocaine infiltration, the more likely there will be lidocaine toxicity. Remember that you should not discharge e a patient too soon because the plasma levels may peak when the patient is at home. The peak of lidocaine absorption is 8 to 12 hours after injection.
  21. Medications inhibiting cytochrome oxidase P450 3A4 A careful history must be taken to ensure the patient has not been taking cytochrome P450 inhibitors that may result in toxicity even with the total lidocaine dose within the usually accepted maximum. Since, the peak of lidocaine absorption is 8 to 12 hours after injection do not discharge e a patient too soon.
  22. Pulmonary Edema Pulmonary edema can be caused by overhydration after injection of too much tumescent fluid, or intravenous fluids, or both, with poor patient or drug monitoring Preoperative medical clearance for any patient with risk factors should be obtained.
  23. Pulmonary Embolism For the last 25 years, pulmonary embolism has been the leading killer among patients who have undergone cosmetic surgery and is responsible for one-fourth of unavoidable deaths. Pulmonary embolism is manifested by one of three clinical patterns: Increased resistance or pain on voluntary dorsiflexion of the foot (Homan's sign) and tenderness of the calf on palpation are functional diagnostic criteria. The onset of sudden dyspnea with tachypnea and no other symptoms Sudden pleuritic chest pain and dyspnea associated with findings of pleural effusion or lung consolidation Sudden apprehension, chest discomfort, and dyspnea result from corpulmonale and systemic hypotension.
  24. Thromboembolism High-risk patients for thromboembolism are: Over 40 years, have a prior history of the thromboembolic disorder, have surgery over one h, are obese, and have postoperative immobilization, estrogen therapy, or a combined procedure. The surgeon should take the necessary precautions taken during the perioperative period. Intermittent compression devices for legs, early mobilization, and low molecular weight heparins can reduce the risk. Drug prevention for deep venous thrombosis is Nadroparin, 7500 UI/d, or enoxaparin, 20 to 40 mg/d but may increase bleeding.
  25. Fat Embolism Syndrome Fat embolism syndrome is rare after liposuction and occurs only after lengthy, combined procedures. Lengthy procedures increase the risk of complications; the optimum length of surgery should not exceed 3 hours. Procedures longer than 2 hours with the patient in the same position require using compression boots or drug prevention of deep venous thrombosis.
  26. Hemorrhages and Internal Bleeding Hemorrhages can be caused by significant vessel perforation, coagulopathy, or internal organ perforation. Bleeding may appear as bright red blood from the incision site or bloody aspirate. Excessive liposuctioning in a single area may cause bloody fluid to appear in the tubing. The surgeon should warn not to continue surgery in that area unless a further tumescent solution is used.
  27. Hemorrhages and Internal Bleeding Any history of bleeding problems with prior surgery or the family should be appropriately investigated. Uncontrolled hypertension must be corrected. Medications that might affect platelet function or the clotting cascade must be discontinued to allow sufficient time to return to normal clotting. Compression over liposuction areas will help limit bleeding. If the patient's clinical status and vital signs are stable, conservative measures such as volume replacement may be taken. Intravenous fluid resuscitation may be enough if the bleeding is not over 15 % of the blood volume.
  28. Hemorrhages and Internal Bleeding Significant internal bleeding presents as abdominal pain, orthostatic hypotension, and shock. Postoperative dizziness and feeling faint should not be considered a drug reaction or dehydration until after the hemoglobin (Hgb), or the hematocrit (H.C.T.) is checked. Low Hgb or H.C.T. should be followed for several weeks. It may take a few weeks for the blood count to return to normal, but usually, the patient can resume regular activity after the Hgb reaches 8 g. However, some patients with more blood loss may require dextran, albumin, or blood to restore the blood volume. Surgical exploration may be necessary if the bleeding continues, and conservative measures do not work. If the blood is retroperitoneal, a C.T. scan may be required.
  29. Perforation of the Abdomen Internal organ perforation must be regarded if unusual abdominal pain or chest pain occurs postoperatively. Perforation of the abdominal wall is most likely to happen in the presence of a hernia or an abdominal wall scar that can divert the direction of the cannula. Patient positioning might expose areas to undesired trauma during suction lipectomy. The cannula type is another important consideration since blunt cannulas are safer than small sharp ones. Care should be taken when using power-assisted cannulas and even ultrasonic or laser technologies since the tissue resistance changes make the penetration of undesired structures easier.
  30. Perforation of the Abdomen Liposuction must be performed with great caution and without abrupt gestures. Liposuction must be tangential, with good orientation and control of the depth of the cannula (on the other hand), without ignoring the risk of intraperitoneal perforation. The surgeon should control the orientation of the cannula, which must not be oriented deeply in the direction of the viscera. The non-dominant hand should always feel the end of the cannula. When the cannula is not palpable, the surgeon should reassess the technique and consider the possibility of perforation. The umbilicus should be avoided in patients with previous abdominal surgery or a case of an abdominal scar. Instead, an incision in the submammary or sub umbilical should be used. This precaution will avoid passing through an umbilical hernia or a diastasis of the median line.
  31. Perforation of the Abdomen It may be challenging to examine the abdomen directly by pressure because liposuction alone will cause pain in the area. The presence of rebound tenderness usually indicates peritonitis. A perforation can be sutured under certain circumstances by a general surgeon after rigorous exploration and if the diagnosis is early enough
  32. Chest Perforation Severe chest pain, especially with dyspnea, may indicate perforation in the chest. Chest X-ray will usually show a pneumothorax, and insertion of a chest tube will relieve the pain and dyspnea. Liposuction over the ribs can be aided using pressure on the lower ribs with the flat portion of the non-dominant hand, which will result in the cannula quickly going over the ribs instead of under with perforation into the chest
  33. Infection The occurrence of infection in a clean surgery case is approximately 1 % in outpatient surgery centers and 3 % in hospital surgeries. Liposuction's low infection rate is due to the combination of sterile techniques, small incisions, and the antibacterial effects of lidocaine. Post-liposuction infection should be diagnosed as early as possible to prevent serious complications. When infection occurs, patients exhibit signs of inflammation, micro-abscesses, and purulent wound drainage. Microorganisms were isolated from the purulent drainage and identified by routine microbiologic techniques. The most common organisms are typical skin flora, notably Staphylococcus and Streptococcus. The community-acquired MRSA is often sensitive to trimethoprim-sulfamethoxazole and Clindamycin.
  34. Severe Infection Infection can be avoided with total antisepsis and proper antibiotics given. I use I g of intravenous cephalosporin intraoperatively. The patient will continue their antibiotics start one day before the surgery. It is essential that wounds be kept clean and that any change in the wound site is reported to the physician immediately. Patients with severe pain or redness that does not improve with first-line treatment should have the possibility of rare causes: necrotizing fasciitis, Toxic shock syndrome, atypical mycobacterium, herpetic viral infections, or fungal infections. Necrotizing fasciitis usually provokes widespread necrosis of the superficial and deep fascia, which is associated with severe systemic toxic reactions. Mycobacterium should be considered when an infection appears ten days to 6 weeks after surgery and is in the form of a mass with overlying redness
  35. Toxic Shock Syndrome Toxic shock syndrome presents as: Fever (above 102 °F) Rash (diffuse, macular erythroderma) Desquamation (1–2 weeks after onset, especially of palms and soles) Hypotension Negative results of the causative agent. Involvement of three or more organ systems: Gastrointestinal (vomiting, diarrhea at onset) Muscular (myalgia, elevated creatine phosphokinase) Mucous membrane (conjunctiva, oropharynx) Renal (blood urea nitrogen or creatinine more than two times average) Hepatic (bilirubin, SGPT, SGOT more than two times normal) Hematologic (fewer than 100,000 platelets)
  36. Severe Infections Severe infections require vigorous prolonged treatment involving surgical debridement, antibiotics, and circulatory and respiratory care. Routine laboratory tests, contrast MRI, and biopsy can help diagnose. Unfortunately, severe infections can lead to significant scarring.
  37. Aesthetic Complications The increasing number of liposuction procedures has led to a growing number of iatrogenic fat tissue deformities, so the need for corrective procedures has also increased. The most common aesthetic complications are as follows: edema, ecchymosis, under-correction, overcorrection, irregularities, seroma, hematoma, cutaneous hyperpigmentation, and liquefied fat. Keeping the preoperative photographs visible during surgery can check what the deformity looks like with the patient standing
  38. Edema and Bruises Postoperative edema and ecchymosis occur to varying extents in all patients. The degree of postoperative bruising depends on the individual patient, surgical technique, and postoperative care. Any gentle, uniform skin compression will constrict the interstices within the collagen bundles of the dermis and restrict the oozing or trickling of red blood cells, decreasing or preventing visible bruising.
  39. Edema and Bruises An infrequent occurrence, persistent edema in liposuction, can be distressing to the patient. Prolonged edema can occur up to 3 months post-surgery and is best treated with supportive care and lymphatic massage. Repeat liposuction (in an amount to break up the edematous tissues and flatten the region) with the tumescent technique is usually helpful after several months. Still, it must be followed by adequate compression dressings
  40. Seromas and Hematoma The collection of serous fluid in the liposuction area may be due to irritation of the tissues by the traumatic procedure but is more frequently the result of concomitant over-suctioning of a single site with undermining of a flap allowing a cavity to form. Most postoperative hematomas occur within the first 24 h. Sometimes a hematoma may appear first and be replaced over time with serosanguinous fluid and then serous fluid
  41. Seromas and Hematoma A loose closure of cannula sites, postoperative compression garments, and expression of residual fluid over liposuction areas at the end of the procedure can reduce the incidence of seroma formation. A persistent fluid collection following liposuction may be treated with needle aspiration followed by adequate compression dressings. Repeated aspiration is repeated every few days. If the collection becomes chronic (over four weeks), the fluid should be aspirated, and an equal amount of room air injected into the cavity to irritate
  42. Hyperpigmented Scars Hyperpigmentation following liposuction can be in the scars or the area of the liposuction. Incision sites may be irritated by the multiple fast passes of the cannula resulting in a reddening around or incision site that can lead to a hyperpigmented scar. Access sites should be wider than the cannula's diameter, and the surgeon should place accessory sites as needed. The hyperpigmented scar is treated as post-inflammatory hyperpigmentation. Treatment consists of 4 % hydroquinone, cream, or gel, rubbed into the affected area twice daily. Recently, I routinely rubbed all access sited with fat extracted; the results are fantastic. During the day, an effective sunscreen should be utilized, unnecessary sun exposure must be avoided, or protective clothing must be worn
  43. Asymmetry Photographing is of utmost importance as a guide for the surgeon during the surgery and postoperative comparison. Some patients forget what they looked like before surgery. Many patients with scoliosis have a deformity in the dorsal region that causes the accumulation of fat more on one side than the other. They usually only note this difference after the procedure. The difference can be seen when you show them similar before-and-after pictures side by side.
  44. Asymmetry Asymmetry can be corrected by removing more fat from the excess, liposhifting fat into the depressed area, or re-injecting autologous fat. Asymmetry can be avoided by being aware of the amounts of fat and fluid removed from each side so that there is no large discrepancy. Observing the results at the end of liposuction may disclose further areas that need correction.
  45. Loos Skin Loose skin after liposuction results from excessive fat removal beyond the innate ability to adequately retract or be redraped. Loos skin problems occur more in: Abdomen: especially with large panniculus. Arms: especially elderly patients and obese patients. Medial thighs: postoperative loose skin is a significant problem in many patients. Treatment for loose skin requires a surgical approach with substantial scars.
  46. Contour Deformities The increasing number of liposuction procedures has led to a growing number of iatrogenic fat tissue deformities). Liposuction sequelae can result from under-correction (insufficient fat removal,) overcorrection (excessive fat reduction), and irregular fat removal (with noticeable and visible irregularities.).
  47. Contour Deformities Treatment consists in freeing the fibrous adherences, aspirating fat from the high areas, and injecting fat into the depression and fat shifting. Using small cannulas, not performing superficial liposuction, turning the suction off when exiting incisions, crisscrossing areas, constantly analyzing areas (visual and tactile), and proper positioning can all help reduce the chance of contour irregularities.
  48. Nodularity, Fibrosis, and Scaring Infection, especially mycobacterial, can leave a mass that will not resolve. Subcutaneous nodularity following liposuction (residual hematoma or seroma) is often associated with an inflammatory component that might end in fibrosis or scarring. Folds in the garment can result in indentations and subcutaneous fibrosis.
  49. Nodularity, Fibrosis or Scar Energy-dependent liposuction produces tissue trauma that might result in internal fibrosis, skin, and scarring. Hypertrophic or keloid scars treatment includes steroid injection, re-excision, silicone gel sheeting, pressure therapy, or a combination of these.
  50. Nodularity, Fibrosis, and Scaring The garment should be checked on the first postoperative day, and the patient should be informed of how to prevent or limit folds in the garment (especially an abdominal binder). Initial treatment will resolve the complication faster than waiting for the fibrosis to mature into a scar. The conservative course of treatment for residual fibrosis from any source consists of the following: I give long-acting steroids 40mg I.M. single dose for patient compliance I use monopolar radiofrequency started at least three weeks after surgery for one session /week for 3-6 treatments. I inject a mixture of 0.5mL verapamil, 0.5 mL triamcinolone, and 1 mL lidocaine.
  51. Neurovascular Complications An abnormal, increased sensitivity or decreased sensation are common sequelae of liposuction, which will gradually improve three to six months after surgery. Acute median nerve compression has been reported from administering large amounts of intravenous fluids during liposuction—the edematous nerve compression resolved with an elevation of the extremities and diuretics. Chronic pain may be due to a small neuroma that can be removed surgically
  52. Neurovascular Complications Erythema ab lipoaspiration is persistent, reticulated erythema, as a result of excessive superficial liposuction. Unfortunately, no treatment exists for this chronic reticulated erythema, and it does not seem to improve with time. Venous areas in the ankles and calves may persist for six months or a year. Proper compression is usually the key to prevention. Remember that excessive extremity compression can result in venous thrombosis and possible embolic disorder
  53. Neurovascular Complications Skin necrosis is more likely to occur with cannulas with sharp edges and turning the openings toward the skin surface disrupting the subdermal plexus of vessels Chronic smokers who do not stop smoking before and after surgery have a high incidence of necrosis
  54. Neurovascular Complications Two patients were treated by U-PAL in the axilla for hyperhidrosis, one developed a purpuric skin rash on one side associated with hematoma. The patient was treated conservatively.
  55. Neurovascular Complications The other patient developed a more severe reaction with oozing (vasculitis-like rash) on both arms with skin necrosis in both axillae. Skin necrosis progressed to full-thickness ulceration and ended in axilla scarring. Both patients were done by a novice plastic surgeon.
  56. Neurovascular Complications Skin necrosis progressed to full-thickness ulceration and ended in axilla scarring. Both patients were done by novice plastic surgeon.
