FEATURES OF ARTERIAL BLOOD SUPPLY IN THE LOWER THIRD OF THE LEG AND ANKLE JOINT IN INDIVIDUALS WITH ATHEROSCLEROSIS OBLITERANS OF THE LOWER EXTREMITIES

Diseases of the cardiovascular system in most economically developed countries occupy a leading position among the causes of morbidity, disability and mortality. In 60-80% of patients with obliterating atherosclerosis of the vessels of the lower extremities with multiple and distal forms of pathology, severe ischemia develops, leading to amputation of the limb in 20-30%. Objective: based on the data of X-ray contrast angiography, show the features of arterial blood supply to the lower third of the leg and ankle joint and evaluate the compensatory potential. The images of 20 patients with atherosclerosis obliterans of the lower extremities were studied. Thus, we can say that the compensatory blood flow in these areas is well developed. But a large number of anastomoses on angiograms with atherosclerosis was not characterized by adequate blood supply, in this regard, it was manifested by the depletion of the compensatory capabilities of the vascular bed and its gradual defeat, resulting in ischemia and foot necrosis.
