Polytetrafluoroethylene (PTFE) was compared to autogenous saphenous vein (ASV) m 133 femoropopliteal and femorotibial or peroneal bypass procedures performed for limb salvage during a 4-year period. PTFE was used as an alternative prosthesis in the absence of a suitable ASV. Sixty-nine femoropopliteal bypasses (FPBPs) were studied-36 with ASV and 33 with PTFE. Sixty-four femorotibial or peroneal bypasses were categorized as femoral distal bypasses (FDBPs)-34 with ASV and 30 with PTFE. With a 3-year clinical follow-up, cumulative function rate (CFR)-patency including thrombectomy-for FPBP with ASV was 65% as compared to 53% for PTFE (P > 0.05), whereas the limb salvage rate (LSR) was 75% with ASV and 56% for PTFE (P > 0.05). However for FDBP, the CFR was 55% for ASV and 7% for PTFE, whereas the LSR was 55% with ASV and 26% for PTFE. The cumulative patency rate (CPR)-initial thrombosis of a prosthesis as an endpoint-was not significantly (P > 0.05) different from CFR, suggesting that thrombectomy with or without distal anastamotic revision does not contribute to patency of the PTFE prosthesis in these limb salvage cases. PTFE was a suitable alternative to ASV for FPBP; however, PTFE is recommended for FDBP in selected cases only.
