Possibilities of using endovascular methods of treatment of patients with critical limb ischemia in regional vascular centers

Abstract

General information about the activity of specialists of the regional vascular centers of St. Petersburg in 2011-2015 is presented. and on the private results of the work of the staff of the center of one of the city’s multidisciplinary hospitals with an assessment of the data on the cases of treatment of 403 patients with critical limb ischemia against the background of arterial lesions of atherosclerosis. Four groups of patients were identified: 278 patients who underwent open reconstruction of the arteries of the lower extremities; 51, who underwent endovascular revascularization; 15, who underwent hybrid surgical interventions. Revascularization was not performed in 55 patients. Among the open operations, loop endarterectomy from the aortoiliac and femoral-popliteal segments (190) and shunting arterial reconstructions (45) prevailed. In endovascular interventions, femoral-popliteal-tibial segments were predominantly corrected - 37 cases. Hybrid operations in 100% of cases are performed through accesses through the femoral arteries. In case of refusal of reconstruction due to the absence of an anatomic substrate for the reconstruction of the vessels, primary amputation of the lower limb (15), lumbar sympathectomy (14) were performed. In 30 cases, angiotropic therapy was performed. Complications of open surgical interventions in the early postoperative period were revealed in 21,6%, endovascular - in 15% of cases, hybrid operations were noted in 13,3% (in total91 complications in 70 patients). Thrombosis of the vascular reconstruction area (35%) and inadequacy of perfusion of limb tissues in permeable vessels (19,7%) prevailed in the structure of complications. There were no lethal outcomes. In general, the use of endovascular and hybrid reconstructions of the vascular bed in specialized divisions of medical organizations in patients with critical limb ischemia with multifocal atherosclerosis contributes to a significant reduction in the frequency of negative consequences of surgical revascularization of the lower extremities.
