Twelve patients suffering aortoiliac occlusive disease and superficial femoral artery occlusion have undergone placement of modified aortobifemoral Dacron grafts. The modification consisted of a short Dacron tube (5 cm in length and 8 mm in diameter) sutured to the limb of the bifurcation graft, 2 cm beneath the inguinal ligament. Seven patients have subsequently required unilateral femoropopliteal bypasses to relieve their continuing claudication. The proximal anastomosis of the femoropopliteal bypass was made between a segment of saphenous vein and the previously placed Dacron extension graft. The primary advantage of this procedure is a marked reduction in the dissection needed at the groin level.
