title: [Cerebral oximetry in the perioperative evaluation of the reserve of cerebral circulation in patients with brachiocephalic artery lesions].
abstract: The reactivity of cerebral vessels and the reserve of collateral compensation of cerebral flow were studied in 71 patients with perioperative carotid stenosis of different degrees. Cerebral oximetry was made at rest and during hypercapnic and compression loads. The method's efficiency was demonstrated for the preoperative evaluation of the cerebrovascular reserve in patients with atherosclerotic affection of vessels in the brachiocephalic stem. A comparison of the preoperative and intraoperative dynamics of rSO2 at compression points at the feasibility of using the cerebral oximetry in predicting the degree of reduced regional oxygenation of the brain in the basin of an intraoperatively pinched artery.
