Determination of quantitative and qualitative indicators of venous circulatory disorders, allowing to establish a diagnosis, chronic cerebral venous insufficiency (CVD). Two groups of patients were selected for this purpose. The first group – patients suffering from chronic cerebral venous insufficiency, the second group – healthy, in whom violations of venous circulation were detected. Two groups of 32 patients, comparable in age and sex characteristics, were studied. In addition to the study of qualitative and quantitative parameters of venous vessels, functional tests were performed on all patients. The Valsalva test is the determination of the insufficiency of the ostial valves by the internal jugular veins. A test with verticalization to determine the insufficiency of blood flow through the vertebral veins. Anti-orthostatic test with determination of blood flow velocity through basal veins. Along with the study of the venous vessels of the brain, peripheral resistance indices were measured along the medullary arteries. For statistical analysis of the reliability of the results of the study, the Student's t-test and the Mann-Whitney U-test were used. As a result, venous circulatory disorders detected by ultrasound examination of blood vessels do not allow a full clinical diagnosis of HCVN. Disorders of venous circulation are only predictors of HCVN. To make this diagnosis, first of all, there must be a clinical picture of the disease and data from an instrumental and physical examination. A cross-sectional examination of patients by ultrasound was performed: transcranial dopplerography of brain vessels and duplex scanning of neck vessels.
