NEUROPHYSIOLOGIC FEATURES OF CEREBRAL HEMODYNAMICS IN PATIENTS WITH VERTEBRO-BASILAR INSUFFICIENCY

The article presents the results of own research of cerebral (arterial and venous) hemodynamics state at duplex scanning of neck vessels, transcranial Dopplerography of cerebral vessels in patients with VBI. The increase in the diameter of the internal jugular vein, increase in the blood flow velocity and decrease in the pulsatility index of the basal Rosenthal vein, increase in the LBFV and diameter of the vertebral vein were found in the venous circulation characteristic of patients with venous encephalopathy.
