Successful vein bypass in patients with an ischemic limb and a palpable popliteal pulse.

Patients presenting with an ischemic foot who have a palpable popliteal pulse have not always been considered to be suitable candidates for arterial reconstruction. Since 1976, 32 distal bypasses were performed in 30 such patients, 77% of whom were diabetic. Proximal anastomoses were from the distal superficial femoral or popliteal artery. Autologous vein was used in all cases. There were six graft failures, all of which occurred within eight months. Three failures, which all occurred within the first month, required below-the-knee amputation. Using life-table analysis, the one- and three-year patency rates were both 79%. One- and three-year limb-salvage rates were 89% and 82%, respectively. We conclude that the results of distal vein graft reconstruction originating from the superficial femoral or popliteal artery are comparable with those of any group of patients with arterial occlusive disease of a lower extremity.
