CEREBRAL VENOUS BLOOD FLOW. CONCEPTS OF NORMALITY, PATHOLOGY AND DIAGNOSIS IN CHILDHOOD. PARTICULARITIES OF MANAGEMENT OF PATIENTS IN THE OUTPATIENT SETTING
Disturbances of cerebral venous hemodynamics define development of vascular pathology of a brain in many respects. However directed by the diagnosis and subsequent treatment these disturbances are not considered. The absence of diagnostics algorithm and norms of cerebral venous blood flow limits the possibility of timely therapy at children. The data of a blood flow velocity (maximum linear) in deep cerebral veins of a brain: in straight venous sinus, great cerebral vein of Galen and sinuses cavernous in children in different age groups from 1,5 to 18 years are defined and added by Transcranial Doppler and Color-Coded Duplex (TCD, TCCD).The research of parameters of a cerebral hemodynamics was carried out in the conditions of functional rest and after dynamic tests. We suggest modified tests in children: Valsalva's test, orthostasis test and head-down tilting (antiorthostasis test). Comparison of classical and modified functional tests has been done.
