The elderly patient with severe arterial insufficiency of the lower extremity: limb salvage by femoro-popliteal reconstruction.

To determine the feasibility of limb salvage in elderly patients in whom severe ischemia of the lower extremity is present, the results of femoro-popliteal reconstruction done primarily for limb salvage were reviewed. Of 310 femoro-popliteal bypasses, 72 were performed on patients 70 years of age or older. In the over-70 group, ischemic necrosis was present in 70.8% rest pain in 22.2%, and claudication in 7.0%. Initial limb salvage patients 70 years of age or older was 71.4%. Cumulative limb salvage at 5 years was 51.1% and at 10 years was 44.8%. Operative mortality, including mortality of subsequent amputation, when required, was 8.3%. Appreciable limb salvage can be achieved by femoro-popliteal arterial reconstruction in lieu of primary amputation in elderly patients in whom severe arterial insufficiency of the lower extremity is present.
