[The interaction of humoral, metabolic and myogenic regulation of the cerebral circulation in unilateral occlusion of the internal carotid artery].

Transcranial dopplerography revealed an asymmetry in middle cerebral arteries in unilateral occlusion of the inner carotid artery. The reactivity of cerebral vessels to carbonic acid diminishes on the side of the occlusion. In absence of the brain tissue infarction, surgical revascularization leads to a partial normalizing of the reactivity. The data obtained suggests a considerable alteration of the interaction among humoral, metabolic and myogenic regulations of cerebral blood flow in unilateral occlusion of the inner carotid artery.
