title: Correlations of arterial hemodynamics with the severity of clinical manifestations of vertebrobasilar insufficiency.
abstract: A variety of clinical manifestations of vertebrobasilar insufficiency in virtually the same anatomical disorders of the vertebral arteries indicates the multilevel regulation of the cerebral bloodflow aimed at its stabilization and maintenance. The main arteries of the head and peripheral arteries were studied by Doppler ultrasonography in patients with anatomical disorders of vertebral arteries (atherosclerotic, extravasal compressions, congenital abnormalities, etc.). A relationship between the variability of clinical picture of vertebrobasilar insufficiency and the diastolic bloodflow in the large aortic arteries was detected.
