    Abstract:
    The objectives of this study were to evaluate the results of polytetrafluoroethylene infragenicular bypass grafts with a distal interposition vein cuff in patients with critical limb ischemia in the absence of ipsilateral greater saphenous vein. From January 1997 to June 2002, 58 consecutive below-knee bypass grafts with PTFE and distal interposition vein cuff were performed in 57 patients with a median age of 70.8 years. The distal anastomosis was located at the infragenicular popliteal artery in 18 cases and at tibial vessels in 40. Primary patency, secondary patency, and limb salvage were analyzed using the Kaplan-Meier method. During a median follow-up of 14.4 months (range, 1-50) 26 cases of graft occlusion and 19 major amputations were registered. The primary and secondary patency rates at 12, 24, and 36 months were 57%, 54%, and 47% and 61%, 58%, and 50%, respectively. Limb salvage rates reached 69%, 69%, and 59% at 12, 24, and 36 months. When below-knee revasculanzation is required in patients with limb-threatening ischemia, in the absence ipsilateral greater saphenous vein, PTFE grafts with a distal vein cuff are a reasonable substitute with acceptable long-term patency and limb salvage rates.
