saphenous vein endoscopic harvesting
Also written as: EVH — endoscopic vein harvesting
Minimally invasive technique for obtaining saphenous vein grafts using endoscopic equipment through small incisions rather than long leg wounds.
Full Definition
An advanced surgical technique for harvesting the great saphenous vein for use as coronary artery bypass conduits using endoscopic visualization and specialized instruments through multiple small incisions rather than the traditional long continuous incision. This approach significantly reduces wound complications, improves cosmetic results, and decreases postoperative leg pain and wound healing problems. The technique involves creating a subcutaneous tunnel using CO2 insufflation for visualization while dissecting the vein under direct endoscopic guidance. Side branches are divided using clips or electrocautery, and the vein is removed through one of the small access ports. Endoscopic harvesting requires specialized training and equipment but has become standard practice in many cardiac surgery centers due to improved patient satisfaction and reduced morbidity. The technique maintains vein quality comparable to open harvesting when performed properly.
Usage
Usage note: Document the number and size of incisions used and assess vein quality in operative reports.
