    Abstract:
    Ultrasonic dopplerography and rheoencephalography were employed to investigate cerebral circulation in patients (n-123) with carotid artery atherosclerosis having transient disturbances of cerebral circulation or ischemic apoplexy. The ischemic foci were measured and localized at computed and NMR tomography. The above complex of examinations allowed evaluation of local, regional and overall blood filling of the brain, of collateral flow as well as conclusion on the type of cerebral hemodynamics. Focal lesions seem to arise in inadequate functioning of collateral circulation, that is in patients with unstable and decompensated hemodynamics. Active collateral circulation shown by the absence of noticeable interhemispheric asymmetry proved prognostically favourable. Administration of vasoactive drugs to patients with decompensated cerebral hemodynamics may induce stealing syndrome and aggravation of neurological symptoms.
