The article deals with characteristics of the hemodynamics of the extracranial major arteries in patients with different forms of cerebrovascular insufficiency due to occlusive lesions of the brachiocephalic arteries. Clinicoangiographic characteristics of patients with this pathology associated with atherosclerosis and nonspecific aortoarteritis are presented. Angiography showed two variants of occlusive damage to the brachiocephalic arteries: bicarotid and multiple. The authors were the first to use comprehensive examination of patients with the employment of the spectral computerized analysis (SCA) of ultrasonograms (USG) of the common carotid and suprapubic arteries and ultrasonic angiography with the calculation of the circulation rate in the common carotid arteries. Using SCA of USGs criteria of different degrees of stenosis of the common and internal carotid arteries were developed. A correlation analysis of the data obtained by SCA of USGs and of the values of the circulation rate in the common carotid arteries was made. The highest correlation of these parameters was observed in patients with stenosis of 60-90% and occlusion of the internal carotid and common carotid arteries.
