Femoral tibial bypass grafts

Abstract

The results of 53 femoral to tibial artery bypass grafts have been reviewed. All were carried out in an attempt to salvage severely ischemic extremities which resulted from arteriosclerotic occlusive disease involving the femoral, popliteal, and tibial arterial systems as demonstrated by arteriography. Most grafts were done with autogenous vein; however, composite grafts comprised of a Dacron prosthesis and an autogenous vein and homologous veins were used in several patients. The initial salvage rate in these pregangrenous extremities was 74%. Fifty-two percent of the grafts remain patent at this writing, a period of 56 months in some instances. This study indicates that most patients with a severely ischemic extremity are candidates for revascularization and should have angiographic studies before amputation is considered.
