COMPARATIVE EVALUATION OF METHODS OF R EVASCULARIZATION OF ARTERIAL BLOOD FLOW I N PATIENTS WITH MULTI-LEVEL OCCLUSIVE-STENOTIC LESIONS OF MAIN ARTERIES IN OBLITERATING ATHEROSCLEROSIS OF THE LOWER EXTREMITIES

Abstract. In Ukraine, from 3 to 10% of the population suffers from occlusive diseases of the arteries of the lower extremities. It is important, that the cause of lower limb ischemia in 45-50% of patients is an atherosclerotic impression. The aim: to study the results of the treatment of multi-level occlusive-stenotic lesions of the main arteries of the lower extremities by choosing the optimal method of surgical revascularization in obliterating atherosclerosis. Materials and methods: the research is based on the results of examination and treatment of 267 patients with critical ischemia of the lower extremity III, IV degrees according to Fontaine. The results. In the case of a combination of occlusion of the superficial femoral artery with stenotic-occlusive lesion of the arteries of the popliteal segment against the background of obliterating atherosclerosis, the use of simultaneous revascularization of the two layers of the lesion allows to expand the indications for revascularization of the arteries in this category of patients and improve the results of treatment. Conclusions: postoperative thrombosis of the reconstruction area in patients, who underwent complex restoration of the patency of the iliac-popliteal arterial segment in various combinations in order to correct the phenomena of critical ischemia occur in 10.5%, and in patients, who underwent restoration of the patency of the iliac-popliteal arterial segment without intervention on arteries of the distal channel – in 27.8%.
