Long-term results of 474 arterial reconstructions for severely ischemic limbs: a fourteen year follow-up

Abstract

A retrospective study of 474 femoropopliteal and femorotibial bypasses performed for limb salvage with a follow-up of up to 14 years is presented. The overall operative mortality rate was 4.2%. Initial limb salvage rate for femoropopliteal was 82.8% and for femorotibial, 67.9%. Cumulative limb salvage rate, as calculated by the life-table method, at 1, 5, 10, and 14 years for femorpopliteal was 67.6%, 59.7%, 54.0%, and 31.5%; for femorotibial 53.9%, 46.9%, 42.2%, and 42.2%. Initial and long-term salvage of severely ischemic lower extremities can be achieved in a large number of patients by revascularization to the popliteal and more distal arterial tree. Therefore we conclude that arterial reconstruction for salvage of severely ischemic limbs should be considered in lieu of primary amputation in all patients with popliteal or tibial run-off.
