  • Title: [Cerebral hemodynamics in stenoses of the internal carotid artery].
    Author: Malyshev NV, Lunev DK, Bragina LK, Musatova IV.
    Journal: Zh Nevropatol Psikhiatr Im S S Korsakova; 1987; 87(1):17-23. PubMed ID: 3825382.
    Abstract:
    The cerebral hemodynamics was studied in 51 patients with varying severity of stenoses of the internal carotid artery (ICA) expressed in transient disorders of the cerebral blood flow or ischemic strokes. To study the cerebral blood flow (CBF), the authors used the 133Xe-inhalational method; in their analysis they also considered the findings of clinical, angiographic and computer-aided tomographic examinations, as well as the rheological parameters of the blood. It has been established that the main characteristics of the cerebral hemodynamics in patients with ICA stenoses are a moderate diffuse reduction of the CBF in both hemispheres of the brain without a clear-cut interhemispherical asymmetry, the absence of the dependence of the CBF on the degree of ICA stenoses, inverse correlation between the degree of the total narrowing of the lumen of all main arteries of the head and parameters of the CBF, as well as a sharper decrease in the CBF in cases where the total stenosis of the main arteries of the head exceeds 40%. The article deals with the pathogenesis of cerebral circulation impairments in ICA stenoses and the selection of the tactics of treating patients.
