[Types and variants of cerebral circulation in healthy young people in clino-stasis and anti-orthostasis]. / Tipy i varianty tserebral'nogo krovoobrashcheniia u zdorovykh liudei molodogo vozrasta v klino- i anti-ortostaze.

This paper presents the results of investigations of 199 apparently healthy individuals aged 18-22 years. Analysis of the findings yielded concepts of the types of cerebral circulation--the types of cerebral microcirculation and the variants brain volumia--the variants of summarized pulse blood filling of this organ. To define the types and variants of cerebral hemodynamics makes it possible to predict the magnitude and direction of brain vasomotor responses aimed at optimizing arterial blood stream into the region and venous blood outflow under antiorthostasis. The types and variants of cerebral circulation that most and least favourable as to a risk for regional venous congestion. The views of the types and variants of cerebral circulation open up fresh opportunities for in-depth study of the most important parameters of cardiovascular performance. A typological analysis of cerebral circulation can find a wide application in clinical practice for "the passportization" of the most important physiological parameters of regional blood flow.
