CLINICAL AND ANATOMICAL CHARACTERISTICS OF PATIENTS WITH ATHEROSCLEROTIC LESIONS OF THE PERIPHERAL ARTERIES AFTER ENDOVASCULAR REVASCULARIZATION OF THE FEMOROPOPLITEAL SEGMENT

Background. Atherosclerotic lesions of the infrainguinal segment arteries are often multilevel and associated with critical limb ischemia, which requires the use of complex endovascular revascularization methods. In this regard, it is important to identify the factors that determine the choice of the revascularization method, as well as to study the effect of the extent and level of arterial lesions on the outcome of interventions such as arterial patency and clinical response in the postoperative period. Objective. To analyze clinical and anatomical parameters of patients with chronic obliterating diseases of the lower extremity arteries subjected to different types of endovascular surgical interventions. Material and methods. We performed a retrospective analysis of 92 medical records of patients with chronic obliterating diseases of the lower extremity arteries after endovascular surgical interventions as well as a questionnaire survey of the patients in order to assess the course of the postoperative period. Results. The indication for the use of endovascular revascularization methods in 58.49% of cases with balloon angioplasty and 58.97% of cases with stenting of the superficial femoral artery and popliteal artery was chronic ischemia threatening limb loss. In patients with stage III lesions according to the GLASS classification, the positive effect after revascularization was more often maintained after balloon angioplasty (in 71.4% of cases) than after stenting of arteries (53.3% of cases). Occlusion of the arteries of the popliteal-tibial region was more often an indication for stent implantation than for performing balloon angioplasty (χ2=4.32, p=0.03). Conclusions. Severe atherosclerotic lesions of the arteries of the femoral-popliteal region often require stent implantation. A more preferable endovascular method of revascularization of the femoral-popliteal segment of arteries with a poor distal bed is the use of balloon angioplasty due to a longer positive effect after surgery for two years (p>0.05).
