Transcript

  • 1.  
  • 2. Dr. Sajid Ali Varicose Vein Topic Presentation
  • 3.
    • The collecting system of veins.
    • The conduits for blood to travel from superficial to the deep veins.
    • The channel through which blood is pumped out of the legs.
    • Contraction of leg muscles pumps blood through one-way valves up and out of the legs.
    Anatomy of V:System of leg A: Superficial venous system B: Perforating veins C: Deep venous system D: Musculovenous pump
  • 4.
    • Superficial System arises from foot & ends at Sapheno- femoral junction or Sapheno- popliteal junction.
    • Formed by union of dorsal digital vein of great toe & dorsal venous arch
    • Ascends ant: to medial malleolus, post: to medial condyle of femur.
    • Prox: it traverses saphenous opening in fascia to enter femoral vein.
    • Along its course, a variable number of named perforating veins may connect to deep system i.e. femoral, posterior tibial, gastrocnemius, & soleal veins.
    A:Superficial venous system 1: Great Saphenous Vein
  • 5.
    • Formed by union of dorsal digital vein of 5th digit & distal venous arch.
    • Runs post: to lateral malleolus, lateral to calcaneal tendon.
    • Runs superiorly medial to fibula and penetrates deep fascia of popliteal fossa, ascends b/w heads of gastrocnemius muscle to join popliteal vein.
    2: Small Saphenous Vein
  • 6.
    • These veins transverse deep fascia of lower extremity.
    • Valves are located just distal to penetration of deep fascia.
    • A number of named perforators are found at thigh, knee & leg.
    • Cockett perforators b/w ankle & knee are special group of perforating veins.
    • Rather than directly connecting sup: to deep venous systems they connect subfascial deep system with post: arch vein which then empties into GSV.
    B: Perforating Veins
  • 7.   Named perforators along the greater saphenous distribution
  • 8.
    • Deep veins accompany the arteries.
    • Usually paired and run with named arteries inside a vascular sheath, this allows arterial pulsation to force blood proximally.
    • Popliteal vein joins femoral vein in popliteal fossa.
    • Femoral vein is joined by deep vein of thigh .
    • Femoral vein passes deep to inguinal ligament to become external iliac vein.
    C: Deep Venous System
  • 9.
    • Foot and calf muscles act to squeeze blood out of deep veins.
    • One way valve allow only upward and inward flow.
    • During muscle relaxation blood is drawn inward thru perforating veins.
    D: Musculovenous Pump
  • 10.
    • Valve leaflets allow unidirectional flow upward or inward.
    • Dilation of vein wall prevents apposition of valve leaflets,resulting in reflux.
    • Valvular fibrosis,destruction, or agenesis results in reflux.
    Venous Valvular Function
  • 11.
    • Long tortuous & dilated veins of superficial varicose system.
    • Varicose veins are bulging veins that are larger than spider veins i.e. typically 3 mm or more in diameter.
    • Force of gravity,pressure of body weight & task of carrying blood from bottom of body up to heart make legs primary location for varicose veins.
    • May also occur else where i.e. Abdominal Wall,Anus,Vulva, Oesophagus.
    What are varicose veins?
  • 12.
    • Visible, palpable veins in the subcutaneous skin greater than 3 mm
    Varicose veins
  • 13.
    • Also called spider veins, hyphen webs, or thread veins.
    • Dilated intradermal venules greater than 1 mm in diameter.
    Telangiectasias
  • 14.
    • Also called blue veins, subdermal varices or venulectasias.
    • Visible, dilated bluish subdermal, nonpalpable veins 1-3 mm .
    Reticular veins
  • 15.
    • Valvular insufficiency of the superficial veins, most commonly at the saphenofemoral junction.
    • Mainly caused by deep vein thrombosis (DVT) that leads to chronic deep venous obstruction or valvular insufficiency.
    • Catheter-associated DVTs are also included.
    • Pregnancy-induced and progesterone-induced venous valve weakness
    • Trauma.
    • This includes any venous malformations.i.eKlippel-Trenaunay variants,avalvulia etc.
    Secondary Congenital Primary Why do they occur?
  • 16. Pathways leading to varicose veins and other clinical manifestations of venous hypertension.
  • 17.
    • Aging causes wear and tear on valves in veins that help regulate blood flow, that wear can cause valves to malfunction.
    • Women are more likely than men to develop condition.
    • Hormonal changes during pregnancy or menopause may be factor.
    • Female hormones tend to relax vein walls.
    • Taking hormone replacement therapy or birth control pills may increase risk.
    Risk factors Age Sex
  • 18.
    • If other family members had varicose veins,there's greater chance you will too.
    • Being overweight puts added pressure in veins.
    • Prolonged immobile standing impairs venous return.
    • Pregnancy,Abdominal/pelvic mass,Ascites,constipation etc inc: risk.
    Genetics Obesity Standing for long periods of time Anything that raises intra-abd:pressure
  • 19.
    • Achy or heavy feeling in legs.
    • Burning, throbbing & muscle cramping in lower legs.
    • Prolonged sitting or standing tends to make legs feel worse.
    • Restless” legs at night.
    • Appearance of spider veins in affected leg.
    • Skin ulcers near ankle, which represent severe form of vascular disease & require immediate attention.
    • Redness, dryness & itchiness of areas of skin - termed stasis dermatitis or venous eczema b/c of waste products building up in leg.
    • Skin above ankle may shrink (lipodermatosclerosis) b/c fat underneath skin becomes hard.
    Symptoms
  • 20.
    • A careful inspection & documentation of the site of varicosities is extremely important.
    • Look along distribution of Long saphenous vein i.e. Medial side along length of leg.
    • Next look along distribution of Short Saphenous vein i.e. Below knee, posterior & lateral aspects of leg.
    Signs
  • 21.
    • Varicosities can lead to major complications due to poor circulation thru affected limb.
    • Extremely painful ulcers may form on skin particularly near ankles.
    • Pigmentations & skin changes ie.brownish darkening of skin resulting from extravasated blood that causes lipodermatosclerosis.
    • Development of carcinoma or sarcoma in longstanding venous ulcers.
    • Blood clotting within affected veins termed sup:thrombophlebitis that can extend into deep veins becoming more serious problem.
    • Acute fat necrosis can occur, esp: at ankle of overweight pats with varicose veins.
    Complications
  • 22. Venous stasis ulcer Lipodermatosclerosis
  • 23.
    • This is physical exam: technique to localise valves that are incompetent
    • Lie patient down & raise leg attempting to drain varicosities
    • Using either tourniquet or fingers put pressure over SFJ to occlude it & ask patient to stand
    • If varicosities don’t refill indicates SFJ incompetence & if do refill then leaky valve is lower down
    • Now try and locate incompetent perforators
    • Place tourniquet aprox: over area of each perforator i.e.mid thigh,sapheno popliteal,calf perforators
    • If varicosities don’t refill that perforator is incompetent & if varicosities do refill continue down leg
    Diagnostic Procedures A: Trendelenberg / Tourniquet Tests
  • 24.
    • This is also physical exam: technique in which tourniquet is placed over prox: part of leg to compress any sup: varicose veins while leaving deep veins unaffected.
    • Pat walks to activate calf-muscle pump which normally causes varicose veins to be emptied.
    • If obstruction of deep system exists then activation of calf-muscle pump causes paradoxical congestion of sup:venous system and engorgement of varicose veins resulting in positive test.
    • To verify pat is then placed supine & leg is then elevated (Linton test).
    • If varices distal to tourniquet fail to drain after a few seconds again deep venous obstruction must be considered.
    B: Perthes Maneuver / Linton Test
  • 25.
    • Doppler transducer is positioned along axis of vein with probe at angle of 45° to skin.
    • When distal vein is compressed audible forward flow exists .
    • If valves are competent no audible backward flow is heard with release of compression.
    • If valves are incompetent an audible backflow exists.
    • These compression-decompression maneuvers are repeated while gradually ascending limb to level at which reflux can no longer be appreciated .
    C: Doppler Auscultation
  • 26.
    • Duplex US with color-flow imaging sometimes called triplex ultrasound.
    • This is special type of 2-dimensional ultrasound that uses Doppler-flow information to add color for blood flow in image.
    • Vessels in blood are colored red for flow in one direction and blue for flow in other with graduated color scale to reflect speed of flow.
    • Venous valvular reflux is defined as regurgitant flow with Valsalva that lasts great than 2 seconds.
    D: Duplex US
  • 27.
    • This is a physiologic test,using plethysmography.
    • VRT is time necessary for lower leg to become infused with blood after calf-muscle pump has emptied lower leg.
    • In healthy subjects VRT is greater than 120 seconds
    • In pats with significant venous insufficiency VRT is abnormally fast at 20-40 seconds.
    • VRT of less than 20 seconds is markedly abnormal & is nearly always symptomatic.
    • If VRT is less than 10 seconds venous ulcerations are likely.
    E: Venous Refilling Time (VRT)
  • 28.
    • Most sensitive & most specific test to find causes of anatomic obstruction.
    • MRV is particularly useful b/c unsuspected nonvascular causes for leg pain and edema may often be seen on scan image when clinical presentation erroneously suggests venous insufficiency or venous obstruction.
    • This is expensive test used only as adjuvant when doubt still exists.
    F: Magnetic Resonance Venography (MRV)
  • 29.
    • Elevating legs often provides temporary symptomatic relief.
    • Wearing of graduated compression stockings with pressure of 30–40 mmHg has been shown to correct swelling, nutritional exchange & improve microcirculation in affected legs.
    • Caution should be exercised in patients with concurrent arterial disease.
    • They are offered in different levels of compression.
    • They are constructed using elastic fibers or rubber which help compress limb, aiding in circulation.
    Treatment 1: Compression Stockings A: Non-surgical Treatment
  • 30. Compression stockings
  • 31.
    • It is commonly performed non-surgical treatment.
    • Often used for spider veins & varicose veins that persist or recur after vein stripping.
    • Sodium tetradecyl sulphate etc is inj: in veins to make them shrink.
    • Sclerotherapy can also be performed using foamed sclerosants under ultrasound guidance to treat larger varicose veins including GSV & SSV.
    • In U/S guided sclerotherapy u/s is used to visualize underlying vein so surgeon can deliver and monitor injection.
    • Microsclerotherapy is used to treat spider veins & other very small varicose veins.
    2: Sclerotherapy
  • 32.
    • GSV Saphenectomy
    • Surgical removal of GSV have evolved from large open incisions to less invasive stripping.
    • Stripping consists of removal of all or part of saphenous vein main trunk
    • Different devices are used in stripping i.e Mayo stripper, Babcock device, Keller device etc.
    • Perforation-invagination (PIN) stripper is mainly used now a days.
    • Technique of PIN stripping begins with 2-3cm incision made at groin.
    B: Surgical Treatment 1: Open Techniques Cont.......
  • 33.
    • Femoral vein and SFJ are exposed with dissection & all tributaries of SFJ must be identified and flush-ligated to minimize incidence of reflux recurrence.
    • Vessel is then inverted into itself tearing away from each tributary & perforator as stripper is pulled downward thru leg & out thru incision in upper calf.
    • Long epinephrine-soaked gauze or ligature may be secured to stripper before invagination allowing hemostatic packing to be pulled into place after stripping is complete.
  • 34. Perforation-invagination (PIN) stripping
  • 35.
    • SSV Saphenectomy
    • Removal of SSV is complicated by variable local anatomy and risk of injury to popliteal vein & peroneal nerve
    • Saphenopopliteal junction must be located by duplex exam: before beginning dissection.
    • After ligation and division of junction stripping instrument is passed downward into distal calf where it is brought out thru a small incision (2-4 mm).
    • Stripper is secured to proximal end of vein which is invaginated into itself as it is pulled downward from knee to ankle and withdrawn from below.
  • 36.
    • It is extremely useful for treatment of residual vein clusters after saphenectomy & for removal of nontruncal tributaries when saphenous vein is competent.
    • Microincision is made over vessel phlebectomy hook is introduced & vein is delivered thru incision.
    • With traction, as long a segment as possible is pulled out of body until vein breaks or cannot be pulled any further.
    • Another microincision is made and process is begun again and repeated along entire length of vein to be extracted.
    • Pat can go home same day after procedure is done.
    2: Stab or Ambulatory Phlebectomy
  • 37.
    • Laser fiber produces endoluminal heat that destroys vascular endothelium.
    • Seldinger technique is used to advance long catheter along entire length of truncal varicosity to be ablated.
    • Under U/S guidance tumescent solution with local anesthetic is inj: around entire length of vessel.
    • Firm pressure is applied to collapse vein around laser fiber & laser is fired generating heat leading to intraluminal steam bubbles,irreversible endothelial damage & thrombosis.
    • This process is repeated along entire course of vessel
    3: Endovenous (EV) laser Techniques
  • 38.
    • RF thermal energy is delivered directly to vessel wall causing protein denaturation, collagenous contraction & immediate closure of vessel.
    • Metal fingers at tip of RF catheter are deployed until they make contact with vessel endothelium.
    • RF energy is delivered both in and around vessel to be treated.
    • Thermal sensors record temp: within vessel & deliver just enough energy to ensure endothelial ablation.
    • RF catheter is withdrawn a short distance & process is repeated all along length of vein to be treated
    D: Radiofrequency (RF) ablation
  • 39.
    • Endovascular occlusion of Saphenous veins using VNUS ClosureTM Catheter
    A Minimally Invasive Alternative to Vein Stripping Surgery
  • 40.
    • Subcutaneous hematoma is a common complication.
    • Dysesthesias can occur from injury to sural or saphenous nerve.
    • At SFJ accidental treatment of femoral vein by inappropriate RF or laser catheter placement,spread of sclerosant or inappropriate surgical ligation can all lead to endothelium damage.
    • Hard tender lumps can sometimes form along the line of removed vein which usually disappears after few weeks.
    • Keloid scars can occur.
    Post operative Complications
  • 41. Thank You
