title: Alternative conduits for coronary revascularization: a novel approach for harvest of the lesser saphenous vein.
abstract: Previous use of the greater saphenous vein limits the subsequent availability of conduit for coronary artery bypass grafting (CABG). One readily available alternative conduit is the lesser saphenous vein (LSV). During a 4-year period, 34 LSVs were explored in 23 patients using a novel surgical approach. The incision used for LSV harvest was carried through and deep into the muscular fascia, posterior to the tibia, along the length of the leg, developing a fascial-cutaneous flap. The LSV in all patients was imaged before operation by venous duplex scanning. Important anatomic details were mapped on the patient's leg before surgery using indelible ink. Findings at operation correlated well with the duplex imaging results. Of the 34 LSVs explored 31 were judged usable by the operating surgeon. In eight patients bilateral LSVs were used and in two this vein was the only conduit available. Among patients undergoing LSV harvest there was no operative mortality and minimal operative morbidity related to harvesting. Only one wound infection developed at the incision site. There were no documented cases of deep vein thrombosis. A case-control study was performed in which a control group of 25 patients undergoing CABG without use of the LSV were compared with the 23 who had LSVs harvested; patients in both groups underwent preoperative venous duplex studies. There were no significant differences in operative mortality or morbidity rate between groups (statistical power > 0.8 for these negative observations), suggesting that harvest of the LSV is usually successful when used in conjunction with preoperative venous duplex scanning.(ABSTRACT TRUNCATED AT 250 WORDS)
