Abstract
To determine the features of a successful clinical strategy, we analyzed the results of 100 consecutive lower extremity vascular reconstructions performed exclusively for tissue loss and gangrene of the legs and feet. Eighty patients underwent 100 procedures on 80 limbs. Follow-up was 95% complete (every six months, mean 2.2 years). Forty inflow procedures to the femoral artery were performed with 13 simultaneous infrainguinal bypasses. Sixty bypasses were performed from the femoral artery to the popliteal (25) or tibial arteries (35). Sixty-eight percent of the identified ulcerations healed, and limb salvage was achieved in 70% of patients by life-table analysis. The cumulative patency for all reconstructions was 48% (five years), for tibial bypasses 60% (four years). Femoropopliteal bypasses had the poorest patency and healing rates (less than 40%), while combined inflow-outflow procedures and femorotibial bypasses had the highest rates of healing (77%, 66%). There were two operative deaths, three graft infections, seven wound infections, and 12 acute graft thromboses. Vascular reconstructions for extensive tissue loss or gangrene can be performed with a morbidity and mortality comparable to procedures performed for less severe disease with a high rate of limb salvage. The long term success of surgical therapy depends primarily on the most direct revascularization of ischemic, infected tissues, using autologous conduits whenever possible.
