The object of the study were 129 patients (53 male and 76 female), with an average age of 59.3. The youngest patient was 34 years old and the oldest--86. Clinically and paraclinically diseases of the cardiovascular system were confirmed in them: 69 with hypertonic disease, 45 with ischemic heart disease (IHD) and 15 with a combination of both the diseases. The condition of the internal carotid and vertebral arteries was studied by ultrasound doppler sonography. Data for pathological main vessels were established in 91 of the patients (70.54%): sonographically established insufficiency in hemodynamics, stenoses and occlusions. Data about I main vessel affected were established in 49 patients, 2--in 24 patients and 2 and 4 vessels--in 18 patients. Most frequent proved to be the main cerebral lesions in subjects with hypertonic disease and IHD (80%), followed by those with IHD (75.5%) and hypertonic disease (65.2%). A correlation was performed between the sonographically established pathology of cerebral main vessels and the minor objective neurological symptoms.
