[Assessment of arterio-venouse balance of human cerebral hemodynamics]

22 healthy subjects aged from 25 to 45, mean age 32.7+/-5.3, have been observed. Every patient was subjected to diagnosing cerebral hemodynamics carried out every 7 days during 6 weeks. The circulation of common carotid artery, middle cerebral arteries and internal jugular arteries has been studied by means of LOGIQ-500MD (GE MS, USA) apparatus. The determination of arterio-venouse balance of cerebral hemodynamics was shown to be worthwhile for common carotid artery and its homolateral internal jugular artery. Arterio-venouse balance is presented as a ratio of circulation blood velocity in common carotid and internal jugular arteries.
