Results of Arterial Reconstruction of the Foot

Sixty-five patients with critical ischemia required bypass to foot vessels. These procedures were performed by five different techniques: (1) femoral-foot bypass with in situ saphenous vein; (2) femoral-foot bypass with reversed autogenous saphenous vein; (3) femoral-foot bypass with polytetrafluoroethylene (PTFE); (4) popliteal-foot bypass with reversed autogenous saphenous vein; and (5) popliteal-foot bypass with PTFE. The two-year patency rate of femoral-foot bypass with in situ vein (96%) was significantly higher than femoral-foot bypass with reversed vein (42%), while both procedures demonstrated significantly higher patency than femoral-foot bypass with PTFE (0%). Popliteal-foot bypass with reversed vein (92%) was superior to both popliteal-foot bypass with PTFE (27%) and femoral-foot bypass with PTFE (0%). Femoral-foot bypass with in situ vein and popliteal-foot bypass with reversed vein have appreciably increased vein utilization, graft patency, and limb salvage.
