metadata.value: Used in medical practice, schemes of assessment of the arterial bed and prediction of treatment outcomes is ambiguous in its objectivity. Development of new methods for assessment of the arterial bed, of predicting the course of atherosclerosis of the arteries of the lower extremities, to select the optimal method of revascularisation of the arterial bed of the legs is a topical task of science and practice. On the basis of parameters obtained from the analysis of data, an instrumental examination of 10 employees (computer tomography, ultrasonic research of vessels of lower extremities) created a mathematical model of blood flow in the arteries of the legs at different localizations of their occlusive-stenotic lesions. The degree of stenotic changes are standardized: 20 %, 50 % and 75 %, occlusion of the artery. Changes in blood flow that occur with isolated and combined lesions of the arteries were estimated. It was demonstrated that the speed of blood flow in the stenosis of arteries of legs is increased; narrowing of the arteries lower leg > 65 % significantly reduces blood flow, and stenosis of vessels >75 % blood flow practically ceases; when combined occlusive-stenotic lesions of several arteries significant disruption of blood flow is observed with stenosis > 50 %. Occlusive-stenotic lesions not only affects the blood flow in the arteries, but also affects the hemodynamics in other vessels of the lower extremities. Modeling disorders of blood vessels in the feet can be an effective technology for the examination and treatment of patients with failure of blood supply of the lower extremities.
