Arterialization of the venous network of the foot through a bypass in severe arteriopathic ischemia.
With the object of saving a very ischemic extremity, when the classic procedures have been unsuccessful or impossible, the authors are using a modification of San Martin's operation. At present, we are making an A-V fistula with a graft interposed between the femoral or popliteal artery and the peripheral long saphenous vein at the foot or near to it. The distal valves are ruptured. In order to prevent the noxious venous overloading resulting from the distal end-to-end anastomosis, it is important to replace it by an end-to-side anastomosis. Eight patients with intense continuous rest pain and necrotic lesions of the toes and heel have been operated on: 3 failures in spite of well functioning A-V fistula; 2 temporary improvements lasted 7 and 16 months when distal thrombosis of the A-V fistula occurred; 3 good results, maintained during 5 months, 4 3/4 years and 9 1/2 years respectively. Postoperative angiography and scintillography reveal a satisfactory retrograde distribution of blood in the fore foot except in the necrotic tissues.
