Based on the indices of cerebral oximetry, analysed herein is efficiency of oxygen support of the brain in various types of anaesthesiological provision (total and general anaesthesia) in patients presenting with atherosclerosis of the brachiocephalic arteries during carotid endarterectomy. It was shown that at the expense of preserving the mechanism of autoregulation, the use of local anaesthesia provides higher efficiency of cerebral perfusion than general anaesthesia which is evidenced by the values of cerebral oximetry exceeding 60% at all stages of the operation. Dynamics of cerebral oxygenation during occlusion of the carotid arteries in the setting of local anaesthesia suggests high reactivity of the cerebral vessels in this cohort of patients and hence preservation of the cerebrovascular reserve in them.

KEY WORDS: carotid endarterectomy, cerebral oxygenation.
