DISTINCTIVE FEATURES OF CEREBRAL HEMODYNAMICS IN CASE OF CHRONIC DISTURBANCES OF CEREBRAL BLOOD CIRCULATION

Abstract

The authors have examined cerebral hemodynamics in 43 patients aged 45 to 77 with chronic disturbances of cerebral blood circulation caused by arterial hypertension and hemodynamically insignificant atherosclerosis, and performed Doppler ultrasonography of extra- and intracranial areas of major cerebral arteries using multifunctional Angiodin system. All patients had complaints of cerebrostenic and neurological symptoms. Initially, the depressed blood circulation was recorded in the arteries of vertebrobasilar basin, and then the blood flow velocity changes in carotid channels came up to the level of vertebral arteries. A Doppler ultrasound test allowed detecting changes that preceded worsening of symptoms of organic lesions of the central nervous system. The overwhelming majority of cases confirmed correlations of the localisation of neurological symptoms and the basin of reduced blood flow parameters.
