[Functional evaluation of cerebral hemodynamics using transcranial dopplerography and nitroglycerin test in occlusion of the internal carotid artery].
42 patients with one-sided atherosclerotic occlusion of internal carotid artery (ICA) out of acute stage of stroke were examined by means of method of transcranial dopplerography with application of nitroglycerin test. Unstable course of the disease with development of repeated ischemic disorders of cerebral circulation were found in most of the patients with decreased hemodynamic reserves in homolateral hemisphere. Differences revealed were statistically significant. It was established by means of nitroglycerin test that the decrease of pike systolic linear rate of blood flow through the median cerebral artery on the side of ICA occlusion less than 10% was the sign of unstability of cerebral circulation and could serve as an indication for surgical correction of the circulation.
