摘要

FIELD: medicine.;SUBSTANCE: invention refers to medicine, namely to ultrasonic diagnostics in neurology and cardiovascular surgery. Carrying out ultrasonic scanning duplex scanning of carotid arteries with determination of plaque thickness (D) during imaging corresponding to maximum size of plaque, and ulceration depth (H) in an atherosclerotic plaque by degree of plaque surface contrast defect in color Doppler mapping mode. If ulceration depth H1/3D is detected, assigning this parameter 0 points. If observing 1/3D≤H2/3D, is assigned 10 points. If ulceration depth H≥2/3D is detected, assign this parameter 20 points. Contrast-enhanced ultrasonography of carotid arteries is performed. Plaque contrast ratio (C) is determined in relation to the total surface area of the plaque (F), when imaging corresponding to the maximum size of the plaque. When contrasting surface area of plaque C1/3F is assigned to this parameter 0 points. At 1/3F≤C1/2F is assigned 10 points, while C≥1/2F – 20 points. It is followed by bilateral Doppler monitoring of cerebral blood flow with detection of microembolic signals in cerebral vessels, wherein the number of detected microparticles (N) is determined during the observation hour. If no microparticles are detected, this parameter is assigned with 0 points, if N≤5 is assigned to this parameter 10 points, when determining N5 is assigned 20 points. Derived points are summed up. If observing 0 points, an atherosclerotic plaque is considered to be stable. If obtaining 10 to 30 points, the atherosclerotic plaque is considered to be moderately unstable. If observing from 40 to 60 points, the atherosclerotic plaque is considered to be highly unstable.;EFFECT: method provides higher diagnostic accuracy of the degree of atherosclerotic plaque stability by a non-invasive method.;1 cl, 2 dwg, 4 tbl, 3 ex
