In patients with severe lower extremity ischemia (ischemic necrosis or pain at rest associated with physical findings of peripheral arterial insufficiency), diabetes mellitus should not deter thorough arteriography and consideration of arterial reconstruction. Infrapopliteal bypass can produce prolonged limb salvage in diabetic patients in lieu of primary amputation.

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.
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.

A Practice-Related Educational Program has been developed to help the physician in primary practice meet the mounting pressures for continuing medical education. Based on analysis of his practice, the physician tests himself to identify areas of potential improvement. Learning resources appropriate to his educational needs are then made available to him at his home base. A follow-up test determines if the person's learning has been effective, and where further emphasis may be placed.
