Abstract：
:In 112 patients with severe ischemia of the lower limb and without a suitable saphenous vein, 99 femoropopliteal and 22 femorodistal bypass procedures were performed with the modified human umbilical vein (Biograft, Meadox Medicals Inc., Oakland, N.J.). Seventy-eight percent of the operations were performed for limb salvage. In the remaining 22% the indication was severe disabling claudication. Forty-nine percent of the patients had previously undergone arterial reconstruction of the extremity in question. In 36% the distal anastomosis was to the popliteal artery above the knee, in 46% to the popliteal artery below the knee, and in 18% to one of the crural arteries. It was mandatory to perform an additional proximal reconstruction in 38% of the extremities. The observation time ranged from 6 to 60 months, with a mean of 24 months. Two patients died within the first month. The overall cumulative patency rate calculated by the life table method was 67.7% at 1 year, 61.2% at 2 years, and an unchanged 56.6% at 3 to 5 years. The cumulative patency rate in the limb salvage group was higher (58.6%) than the patency rate of the grafts implanted for claudication (46.5%, not significant). Graft patency decreased the more peripherally the distal anastomosis was situated, but we could demonstrate neither a significant relationship between graft patency and runoff nor any prognostic significance in the peroperatively measured flow values. Limb salvage calculated by the life table method was 86% at 1 year and 75.4% at 5 years. It is concluded that the umbilical vein graft is an acceptable alternative for bypass grafting in patients without a suitable autogenous vein.
