Vein, Gore-tex or a composite graft for femoropopliteal bypass.
Experience with a variety of graft materials has suggested that the nature of the material significantly affects long term graft patency. In 126 femoropopliteal bypass grafts performed during a 54 month period, the over-all patency rate for RSV (68.0 per cent at three years) was significantly superior to either Gore-tex alone (34.1 per cent at three years) or a composite graft of RSV below the knee anastomosed to Gore-tex above the knee (49.3 per cent at three years). The composite graft performed significantly better than Gore-tex alone, however, in patients with poor runoff or when a distal anastomosis was performed below the knee. The reason for the superior performance of RSV or the composite over Gore-tex alone probably relates to compliance mismatch at the site of the distal anastomosis. While RSV remains the graft material of choice for femoropopliteal bypass grafting, a extensive role exists for the use of a composite graft rather than Gore-tex graft alone especially in patients with poor runoff with an anastomosis below the knee.
