HYPOTHESIS: Infragenicular polytetrafluoroethylene (PTFE)-venous cuff bypass grafting provides acceptable graft patency and limb salvage rates for limb salvage. DESIGN: Retrospective clinical review of a consecutive series. SETTING: Vascular surgical practice during the interval October 1, 2000, to September 1, 2004. PATIENTS: Fifty-one male and 49 female patients whose mean age was 76.9 years were operated on for tissue loss (67%), chronic rest pain (28%), and severe claudication (6%). Fifty-two percent of patients were diabetic and 49% had undergone previous leg bypass surgery. All patients had absent or inadequate greater saphenous vein, and 84 patients had absent or inadequate arm vein. INTERVENTIONS: One hundred five infragenicular PTFE bypasses were performed in these 100 patients. Distal targets were the infragenicular popliteal (40), posterior tibial (35), anterior tibial (16), and peroneal arteries (14). Sixty-eight venous cuffs were constructed from lesser saphenous vein. MAIN OUTCOME MEASURES: Graft patency, limb salvage, and patient survival were analyzed. RESULTS: Twelve early graft failures resulted in 7 leg amputations. The mean +/- SE 3-year primary patency and limb salvage rates were 64.4% +/- 12.8% and 74.4% +/- 11.9%, respectively. Perioperative mortality was 2.9% and 3-year survival was 38%. Graft follow-up ranged from 1 to 47 months with a mean of 13 months using life-table methods. CONCLUSIONS: For patients requiring arterial revascularization for limb salvage, in which autologous venous conduit is unavailable, distal venous cuff-PTFE bypass provides acceptable patency and limb salvage rates when viewed in the context of short life expectancy for these elderly patients.
