[Peculiarities of the brain bioelectrical activity in patients with atherosclerotic lesions of extracranial branches of the aortal arch].
Bioelectrical activity of the brain was studied in 12 patients with atherosclerotic affection of extracranial branches of aortal arch, using electroencephalography method, tests with hyperventilation and nitroglycerin loading. It was established that in lowering of the blood flow along extracranial vessels the brain functional state is not always disturbing. In 50% of patients the hypoxia signs were not revealed. While the blood flow lowering along extracranial vessels causes disorder of the brain bioelectric activity, strict dependence of the hypoxia severity from the blood flow disorder degree and the affection side was not established.
