Proximal Versus Distal Segments of No-Touch Saphenous Vein Grafts

NCT04284956 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 100

No results posted yet for this study

Summary

The optimum segment of No-Touch veins for bypassing is still undefined. The purpose of this study is to assess the incidence of leg wound complication after No-Touch harvesting of proximal segment of saphenous veins compared to distal segment of veins in the leg. Graft occlusion rates between the two segments of veins for bypassing will also be compared during follow-up.

Conditions

  • Leg Wound Complication After No-Touch Harvestingof Veins

Interventions

PROCEDURE

Proximal and distal segment of saphenous vein harvested by No-Touch technique

two longitudinal incisions are made on the thigh and shank from unilateral lower limb (for harvesting of proximal segment of saphenous vein, incision is started from about 3 or 4cms inferolateral to the pubic tubercle and then extended downward). As previous reported. the adventitia and perivascular tissue are carefully kept intact to avoid damage. Then a margin of about 5 mm from both sides of the vein is created to include the fat pedicle using electrocautery, and all visible side branches are ligated with 4-0 silk or by metal clipping (branches are divided at the pedicle margin rather than the vein trunk). The saphenous vein is then separated from its bed using scissors and electrocautery, together with surrounding tissue.
