Bypass surgery with a large subcutaneous vein in severe ischemic syndromes

The technique of reconstructive operations on small-diameter arteries, in particular on the arteries of the lower leg, is insufficiently developed. Therefore, the success of surgical interventions on such vessels is still insignificant. Moreover, today there is still no completely satisfactory method of restoring blood flow even in the arteries of the femoral-popliteal segment. Almost all surgeons refused to use synthetic prostheses for obstruction of the femoral and popliteal arteries. Equally revised is the attitude to intimotrombectomy for long-range arterial thrombosis. In patients with deep changes in the walls of the arteries, accompanied by circulatory disorders, these operations usually give extremely unsatisfactory immediate results; successful outcomes are rare. With thrombosis, blood circulation not only does not return to the initial preoperative level, but, as a rule, worsens and often requires amputation even in such patients who have been operated on for intermittent lameness.
