Late results with Dardik-biograft in peripheral arterial surgery.
A total of 117 vascular reconstructions below the inguinal ligament were performed using Dardik's human umbilical vein. The indication for surgery was limb salvage in 91.5%. In 61.5% a previous reconstruction had failed. The distal anastomosis was done with the popliteal artery above the knee in 9 cases, below the knee in 41, and with a tibial or the peroneal artery in 60 cases. The umbilical vein was combined with a prosthesis or the autologous saphenous vein in 20 cases. The cumulative patency rates of all reconstructions were 59.6% after 3, and 46.7% after 6 years. Crural reconstructions had a cumulative patency rate of 52% 3 years after surgery. The main factors influencing patency were the preoperative grade of ischemia, the site of the distal anastomosis and the angiographic run-off. It is concluded that the human umbilical vein is the graft material of choice in long length revascularization whenever the saphenous vein is not available.
