title: [Electroencephalogram dynamics in Matas' compression test as a criterion of the efficacy of reconstructive operations on the vessels of the carotid basin].
abstract: EEG recording with Matas' compression test makes it possible to specify the immediate contribution of the carotid artery to the activity of the cerebral cortex neurons. This supplements the quantitative study of the linear and volume blood flow in the carotid bed. The positive result in compression of the carotid artery is characterized by a stereotype reconstruction of the brain biopotentials on the EEG reflecting the beginning of nerve cell hypoxia. Change of the EEG response in Matas' test after reconstructive operations--endarterectomy of the carotid artery and formation of extra-intracranial microvascular anastomosis--points to the contribution of the carotid artery to the general cerebral blood flow under the new conditions. It is noted that the significance of the newly formed vascular bed in the cerebral blood supply increases gradually and individually in different patients. This is evidently determined by the differences in the severity and spread of atherosclerosis of the cerebral vessels, the arterial pressure level in various vascular beds of the brain, the degree of development of anastomoses and synangioses between the branches of the internal and external carotid arteries, etc.
