Abstract

The review is devoted to the generalization of modern data on cerebral hyperperfusion syndrome (CHS). CHS is similar to the luxury perfusion syndrome, hypertensive encephalopathy, posterior reversible encephalopathy syndrome and reversible cerebral vasoconstriction syndrome. The problem of distinguishing CHS and related syndromes is considered. The probable mechanisms of the CHS development after revascularization of carotid and other arteries are discussed: 1) increased cerebral blood flow; 2) violation of cerebral autoregulation; 3) damage to the cerebral vessels by free radicals; 4) destruction of the reflex mechanism of the baroreceptor; 5) the connection of CHS with the trigeminovascular reflex; 6) the connection of CHS with the cerebral arteriovenous imbalance. The importance of studying arteriovenous imbalance as a mechanism of the CHS development is emphasized. The risk factors of the CHS development after carotid endarterectomy and stenting of the carotid arteries are considered.
