  2. 2. IntroductionThe venous drainage system of the lower extremity consists of three sets of veins:Deep veins,Superficial veinsPerforating veins. All veins contain delicate one-way valves that normally open to allow blood to flow toward the heart and prevent blood from flowing in a retrograde fashion after the valves close .
  3. 3. Veins of lower limb1: Superficial veins: Long saphenous vein Short saphenous vein 2: Deep veins : Anterior & Posterior Tibial veins Peroneal vein Popliteal vein Femoral vein3: Perforator veins
  4. 4. Long saphenous vein (LSV)Largest and longest superficial vein of the limb.Begins on the dorsum of foot from medial end of dorsal venous arch.Run 1 to 1.5 inch anterior to the medial malleolus ,along the medial side of the leg , and behind knee .
  5. 5. At the ankle the position of the LSV is constant , lying in the groove b/w the anterior border of the medial malleolus and tendon of tibialis anterior.
  6. 6. In the thigh it inclinesforwards to reach thesaphenous opening where itpierces the cribriform fasciaand opens into the femoral vein3-4 cm below and lateral to thepubic tubercle.
  7. 7. The long saphenous vein and deep fasciaIn the lower 2/3 of leg and in upper 2/3 of the thigh vein lie on deep fascia . Where the vein crosses the knee joint it become more superficial and often subcuticular .
  8. 8. The structures accompanying the LSVIn the leg saphenous nerve lies in close relation with the LSV.The nerve is very closely applied to the vein in lower 2/3 of leg and often injured in exploring or stripping the saphenous vein .In the thigh medial femoral cutaneous nerve run in close relation with vein .
  9. 9. Throughout its length the LSV is accompanied by lymphatic trunks draining the dorsum of foot and anterior and medial aspects of the legs and thigh .This lymphatic drain in superficial inguinal lymph nodes.
  10. 10. Tributaries of LSV and communicationJust below knee LSV receive posterior arch vein (Leonardos vein) which collect the blood from post- medial aspect of calf .Anterior veins of leg(stocking vein) ascend across the shin and join either LSV or posterior arch vein .There is a free anastomosis b/w tributaries of short saphenous vein and venous arch connecting medial ankle perforating vein and this medial ankle perforating veins are connected with LSV in lower third of leg .
  11. 11. In the thigh before entering in the saphenous opening it recieves1. Anterolateral vein2. Posteromedial vein of thigh3. Superficial external pudendal vein4. Superficial epigastric vein5. Superficial circumflex iliac vein6. Deep External Pudendal Vein In the lower third of thigh long saphenous vein connect with femoral vein in hunter’s canal by long perforating vein ( hunterian perforator)
  12. 12. Short saphenous vein(SSV)It begins by the fusion of number of small veins below and behind the lateral malleolus . Here vein runs with the large sural nerve up to lower third of leg. SSV is runs upward up to the middle of the popliteal space, where it passes deep to fascia to enter into popliteal vein .
  13. 13. In the lower third of the calf it lies on the deep fascia and cover by skin and superficial fascia .In the middle third of leg it enters in the intrafascia compartment in the aponeurotic investment of the gastrocnemius muscle .
  14. 14. Upper third of leg it penetrates the deep fascia and enter popliteal space and lie b/w head of two gastrocnemius muscle which lies 1.25cm below the transvers skin crease behind knee .Here SSV join popliteal vein .
  15. 15. Structures accompanying the SSVSural nerve in lower third of legLymphatic trunk which drains lateral aspect of foot and drain in the popliteal lymph nodes.
  16. 16. Where the vein passes through fascia Posterior cuteneous nerve emerges out from deep to superficial.In the upper part of vein it communicates with LSV via the posteromedial vein of Leg.SSV may run above the popliteal space and end in deep veins in lower thigh or may end in LSV in upper thigh.
  17. 17. Deep veinsThis veins lie in deep fascial plane and are supported by powerful muscles of leg.These are 1: Anterior and posterior Tibial veins 2: Peroneal vein 3: Popliteal vein 4: Femoral veinThese veins accompany with Arteries.
  18. 18. Perforating veinsThese are communicating veins b/w superficial and deep veins .Two type: 1 Indirect veins 2 Direct veins
  19. 19. 1. Indirect perforating veins: These consist of small superficial veins which penetrate the deep fascia to connect with vessel in muscle and in turn end in Deep vein.
  20. 20. Direct perforating veins :These directly connect superficial veins with deep veins
  21. 21. Direct perforator In thigh : Adductor canal perforator connects long saphenous with femoral vein in lower part of adductor canal. (hunterian’s perforator) In the lower thigh on medial aspect Long SV connect femoral vein via DODD’s Perforator Below knee : Perforator connects long SV or post-Arch vein with posterior tibial vein knows as BOYD’S Perforator. May/Kuster
  22. 22. In leg :1.Lateral perforator is presented at the junction of mid & lower third of leg .It connect SSV with peroneal vein.2. Medially there are three perforator which connect posterior arch vein with posterior tibial vein , know as COCKETT’S Perforator
  23. 23. Upper medial perforator lies at the junction of middle and lower third of leg.Middle medial perforator lies 4Inch above the medial malleolus .Lower medial perforator lies posterio-inferior to the medial malleolus .
  24. 24. Surgical modalities forVaricose veino Ligation & Stripping of veino Ligation of Incompetent Perforators 1.Open subfascial ligation of perforators 2.Subfascial Endoscopic ligation of perforators 3,Extra fascial ligation of perforatorso Sclerotherapyo Endovenous Laser Ablationo Radiofrequency ablation
  25. 25. SurgeryLigation and stripping of varicose vein :Indication :LSV /SSV incompetency .Perforating vein incompetency.
  26. 26. ContraindicationsDVTPregnancyThrombophlebitisPeripheral vascular disease
  27. 27. Pre-op marking of varicose veinAs the varicose vein disappear when pt lies down on operating table so its essential to mark the course of the major superficial tortuous vein to be removed.
  28. 28. Steps of surgery for LSVAfter anesthesia proper position is given.The whole table is tilted head down to an angle of about 10 degree. (trendlenberg position)
  29. 29. Incisions :1. Hockey stick incision2. Oblique incision Incision is kept at groinat Saphenous opening 3- 4 cm below and lateral to pubic tubercle.
  30. 30. After division of deep layer of fascia , saphenofemoral junction is exposed.
  31. 31. Then flush saphenofemoral ligation (& tranfixation) done with ligation of all tributaries of long SV .
  32. 32. Then stripper is passed down the saphenous vein and directed downward by finger ..
  33. 33. Stripper delivered through small incision over ankle on medial aspect
  34. 34. Vein is tied with stripper and then stripper is slowly and steadily pulled out through lower wound.The ‘vein bolus’ is withdrawn slowly from the lower wound.
  35. 35. The residual veins are then ‘wormed out ‘ using multiple stab avulsions using vein hooks ,from the preoperative marked sites.Post operatively limb elevation and compression stockings are given .
  36. 36. STEPS OF SURGERY FOR SSVAfter anesthesia proper position is given.The patient must be face down and the knee is flexed a little, by placing sandbag under the ankle .Some prefer lateral leg position.The foot of the table is tilted up a little, so that legs are above the heart.
  37. 37. Incision is kept atleast 5 cm long, transversely across the popliteal fossa, in one of the transverse line of skin about the level with knee joint.The incision is deepened until the deep fascia and short saphenous vein lies deep to this.The fascia is divided transversely in the line of incision.
  38. 38. The short saphenous vein is then seen or sought for betweeen the two heads of gastrocnemius.As soon as the SSV is identified, it is lifted up in a pair of artery forceps and the knee is flexed still further.Then flush saphenopopliteal ligation (& transfixation) done with ligation of all the side branches of SSV, right upto its junction with the popliteal vein.
  39. 39. Then stripper is passed down distally, directed by finger.And delivered to point below external malleous through a small transverse incision.
  41. 41. IMMEDIATE POST-OP CAREThree factors to be kept in mind in the first week :1 Maintenance of firm elastic pressure over whole limb.2 Regular movement and exercise of the legs3 Elevation of the foot of the bed 6 to 9 inches so that the legs are just above the heart level when the patient is in bed.
  42. 42. POSITION :The foot of the bed is raised 6 to 9 inchesPatient is not allowed more than 2 pillows.
  43. 43. BANDAGING :The original firm crepe bandage put on at the operation should remain untouched for seven days
  44. 44. GETTING UP :Started 24 hrs after the operation.When the foot is placed on the ground for the first time, extra firm webbing elastic bandage are placed over knee and ankle.At 7 days the stitches are removed.A firm webbing elastic bandage from ankle to knee is worn through-out the day for a whole fortnight.
  45. 45. Post operative complicationsHaematoma and buising- normally bruise absorbed within 3-4 wks- small haematos get reabsorbed large haematomas more than 4 cm evacuated with sterile precaution under LA with sterile precautionsLymphatoma-Generally occurs on 5-6 post op day-Get absorbed within 1-2 wks-Should not be interveined as may lead to lymphatic fistula formation
  46. 46. Wound sepsisPost operative saphenous neuritisLymphoedema of legInduration of stripper tractDVT and embolism
  47. 47. Extra fascial ligation ofperforators(Cockettsprocedure)Not commonly employedAim is to clear all the extrafascial veinsMore traumatic due to adherence of subcutaneous fat and connective tissue to the fascia
  48. 48. Subfascial EndoscopicPerforator SurgeryPeople who sufferwith leg ulcers dueto incompetentvenous perforators
  49. 49. Indication :Incompetent perforating veins in calf with no superficial venous reflux or no evidence of DVT on Doppler .Patient with LSV / SSV varicosity with ulcer
  50. 50. ProcedureUsing spinal or general anesthesia a ¾ inch incision is made on the inside of the calf. An instrument is inserted deep to the fascia of the leg and a large balloon is inflated with water to create a working space.The balloon is then emptied and the space is insufflated with air.The camera is inserted and the perforator veins can be seen in the space passing from superficial to deep layers.
  51. 51. Another small incision is made in the calf for passage of another instrument. The perforator veins are carefully dissected, Clips are applied and the veins are divided if necessary. All trocars are then removed and the wounds are closed. The patient is generally sent home the same day of surgery with elastic stocking.
  52. 52. Obliteration of venous lumen - Methods1. Foam Sclerotherapy2. Laser3. Radiofrequency Ablation
  53. 53. Foam SclerotherapyPrincipal :By injecting sclerosant into a varicose vein, destroy its endothelium in that area , and thus induce an aseptic thrombosis which organises and closes the vein.
  54. 54. Indication : Contraindication :Residual vein after Pregnancy surgery Pelvic tumorLarge venous Sup thromboplebitis at telangiectases. the time of procedureIsolated small dilated DVT veins Previous h/o reaction to sclerosant
  56. 56. `PROCEDURE :Depending upon the size of vein to be occluded, sclerosant is taken in 20 ml syringe and connected to another syringe with 4 times the amount of air.By repeated to and fro motion of the solution and air into syringes , dense white foam is prepared .
  57. 57. After giving position under USG guidance needle is inserted into the vein .And sclerosant is injected into the vein .Not more than 20 ml foam should be injected at one sitting ,Multiple sitting may be required for successful obliteration of veinThe foam being dense , does not “run-away” up the vein, it require massaging the skin over varicose vein.
  58. 58. Immediately after foam injection compression stocking is applied and patient is mobilized .Patient can go home on the same day of procedure.After 48 hr of procedure USG is done to R/o DVT
  59. 59. Advantage DisadvantageCheap Not suitable for SFJ/SPJEasy to learn obliterationTruly an OPD procedure ThrombophebitisCan be repeated many Pigmentation over skin times More than 3 wksNo anesthesia required compression is required
  60. 60. Endovenous Laser Treatment (EVLT)Principal :EVLT initiate a nonthrombotic occlusion by direct thermal injury to vein wall, causing endothelial denudation , collagen contraction and later fibrosis.
  61. 61. Indication : Contraindication :Long saphenous vein Superficial vein varicosity thrombophlebitisShort saphenous vein DVT varicosity
  62. 62. ProcedureEVLT is done under local anesthesia under USG guidance.Varicose vein is marked preoperativelySupine position is givenVein is canulated with 0.035” J guide-wire via 19G needle.The Laser fiber is then introduce over it under USG guidance upto 2-3 cm distal to SF junction.
  63. 63. Fiber is withdrawn at the rate 1-3mm / sec under USG guidance .This laser fiber causes thermal damage to the venous endothelium(1000 c) and occlusion of lumen by fibrosis.Immediately after procedure compression stockings are given.Patient can be discharge on same day with good analgesics and with compression stockings.
  64. 64. ADVANTAGE DISADVANTAGEMinimal invasive Costly procedure procedure High technical skills reqNo post op scar Color Doppler andDone with local Radiologist is req anesthesia Skin burnsMinimal post-op pain ThrombophebitisRecurrence rate ( at 2 Paresthesia year f/u only 3%
  65. 65. Radiofrequency AblationThis technique based on same principal of EVLTHere instead of laser fiber , special heater probe is inserted which work at 85 -120 cProbe directly comes in contact with vein wall & causes tissue damage .A 45 cm of vein segment takes only 3-5 minPatient can directly go to home after procedure.
  66. 66. TRIVEXAlternative to avulsion phlebectomy for superficial vein excision.In this technique with the help of transcutaneous light, veins are seen and extracted with the help of suction dissector.
