[Rheoencephalographic evaluation of the relations between the changes in cerebral circulation in the areas supplied by specific arteries in patients with cerebral stroke].

Rheoencephalography was made in 105 patients with ischaemic brain stroke during the first phase after the onset of the disease and 10 days later. It was found that the presence of an ischaemic focus in the area of the internal carotid artery induced blood supply alterations within the areas of adjacent++ arteries, i.e. contralateral carotid artery and vertebral arteries. In some cases it became visible in the reg records under the form of reduced or enhanced pulsation of blood flow followed by weaker reactions of changed vascular tonus. Most distinct changes were observed at the onset of the brain stroke. Ten days later these changes became less expressed.
