In 118 patients 144 different reparative operative procedures were performed for ischemia of the extremity, grade II-IV, due to atherosclerotic lesion of arteries of the femoropopliteal zone. In ischemia of the extremity due to an isolated lesion of the superficial femoral artery transplantation of the reversed autovein is felt to be the best method of reconstruction. Transplantation of a synthetic prosthesis may be employed, only if other methods, as the last chance for saving the extremity from amputation, proved to be unfeasible.
