EXPERIENCE OF USE OF DONOR VASCULAR GRAFTS IN SURGERY OF THE MAIN ARTERIES OF THE LOWER LIMB

Abstract

Today, in surgery of the arteries of the lower extremities in diabetes mellitus and atherosclerosis, the autovein is the gold standard. It does not require any selection, conservation, or other preparation methods necessary for its application. However, its use in some cases is limited due to their parametric characteristics (length, diameter), loss of time for their preparation, and their absence. For these categories of patients, the method of choice is the use of vascular allografts. The article presents the experience of 25 cases of post-mortem donor vascular grafts in 24 patients with lower limb revascularization with critical ischemia. All patients were divided into 2 groups: 13 patients were included in the first group with neuroischemic form of diabetic foot syndrome, and 11 patients were included in the second group with obliterating atherosclerosis of vessels (arteries) of the lower extremities. Positive results were noted in 20 patients (83.3%). In the immediate and long-term periods after revascularization with a donor graft (1 - artery, 3 - vein), high amputations were performed in 4 (16.7%) cases, all patients with diabetes mellitus.
