3. Objectives
At the end of this topic student will be able to………
1. Define Vericose veins, venous system, valves in the veins and factors
affecting in venous return
2. Causes, pathophysiology , clinical manifestation and diagnosis
3. Complications, medical and nursing management
4. Define venous thrombosis, etiology, pathophysilogy and clinical
menifestation
5. Lab and physical assessment findings
6. Diagnosis, prevention, treatment and nursing management
4. VARICOSE VEINS
Defined as dilated ,
elongated , tortuous
and palpable
superficial veins as a
result of venous
hypertension .
More common in
males
Long saphenous
system affected in most
cases
5. Venous system
Deep system of veins lies below the deep fascia .
Superficial system of veins lies outside the deep fascia
Perforating veins which pass through the deep fascia joining superficial to
the deep venous system .
6. Valves in the veins
Valves present in
superficial veins
Prevent blood from
proximal to distal
and from deep o
superficial .
Valves can resist
pressure up to 300
mmHg .
7. Factors helping in venous return
Negative pressure during inspiration
Muscles contraction
Competent valves in the veins
8. Etiology
Long hours of standing
Family history
Pregnancy
Aging
DVT
Oral contraceptives
Obesity
9. Pathophysiology
Etiological factors
Changes in vein wall
Over stretching of veins
Increase in size of veins
Secondary valvular incompetence
Backflow
Pooling and further dilation of veins
Varicosity – dilated tortuous veins
10. Clinical manifestations
Cosmetically disfigurement
Dull aches
Muscles cramps
Increased muscle fatigue in lower legs
Ankle edema
Feeling of heaviness of the legs
Nocturnal cramps
Pigmentation and ulceration
14. Management
Avoid prolong standing
Elastic stockings limb
elevation above the level of
heart while lying down
Sclerotherpy
Surgical management ( high
end ligation and striping
Laser fiber produce
endoluminal heat that
destroy the vascular
endothelium
15. Nursing management
Bed rest for first 24 hours , after which the patient begins walking every 2
hours for 5 to 10 minutes .
Elastic compression stockings . Continuously for 1 week after stripping
Foot end of bed should be elevated
Discourage Still standing and sitting
17. Venous thrombosis
Presence of thrombus in a vein and the accompany inflammatory
response in the vessel wall .
Commonly occur in lower extremities .
Complicated by pulmonary embolism , recurrent episodes , development
of chronic venous insufficiency .
If left untreated , it may extend to larger ,with an increased risk of
pulmonary emboli up to 90% .
18. Etiology
VENOUS STASIS
Immobility
Spinal cord injury
Acute MI
Congestive heart
failure
Shock
Venous obstruction
HYPERREACTIVITY
OF BLOOD
COAGULATION
Genetic factors
Stress and trauma
Pregnancy
Childbirth
Oral contraceptives
Dehydration
Cancer
Hyperhomocysteinemi
a
VASCULAR TRAUMA
Indewelling venous
catheters
Surgery
Massive trauma or
infection
Fractured hip
Orthopedic surgery
19. Pathophysiology
Reduced blood flow
Damage to the lining of blood vessels creates a site for clot formation with
platelets aggregation
Thrombus accompanies inflammation ( phlebitis )
dislodgement of thrombi
pulmonary embolism
22. Physical assessment findings
Site of thrombus determines the location of physical findings
Most common site is in the venous sinuses of Soleus Muscle , Posterior
Tibial & Peroneal Veins .( pain in foot ankle and calf )
Femoral Vein Thrombosis (pain in distal thigh and popliteal area )
Iliofemoral Vein Thrombosis ( Pain in entire extremity )
24. Prevention
Early ambulation after surgery
Exercising
Wearing support stockings
Antiembolism stockings
Lifestyle changes i.e weight loss
smoking cessation.
25. Treatment
Goal of treatment is to
1. Prevent formation of additional thrombi
2.Prevent extension and embolization of existing thrombi
3. Minimize venous valve damage
Heat (to relieve venospasm )
Prophylactic anticoagulant drug therapy
Elastic support
SURGICAL TREATMENT
Surgical removal of thrombus
Percutaneous insertion of intracaval filters
26. Nursing management
Assessment of temperature , color ,
tenderness , swelling , & measure
circumference of affected limb
Asses signs for embolization .
Mobilize the client .
15 to 20 degree elevation of the legs
Apply pneumatic compression device.
Keep the limb warm .
Physiotherapy
Do not massage legs
Asses for any bleeding if on
anticoagulant therapy
Educate regarding modification of
risks
Smoking cessation
Weight loss
Compression stockings
Hydrate well
Encourage physical activity e.g walking
and swimming
Pregnancy may cause varicosities because of hormonal effects related to decrease venous outflow ,increased pressure by uterus and increase blood volume
