[The hemodynamic aspects in predicting the course of hemorrhagic stroke (based on ultrasonic dopplerographic data)].
A comparative analysis was performed of clinical-neurological-hemodynamic-structural changes in the acute phase of hemorrhagic insult (HI) in 56 patients who ranged from 19 to 59 years old. Intracerebral hematomas (ICH) appeared to be more commonly seen. Main emphasis was put on potentialities of Doppler Sonography (DS) in hemodynamic assessment of cerebral bloodflow condition in patients with hemorrhagic insult. Parenchymal hemorrhage was found out to play the greatest pathogenetic part in the time course of cerebral decompensation in HI, with subarachnoidal hemorrhage making a lesser contribution. ICH leads to compression of brain tissue, whereas extravasal compression of cerebral arteries imitates secondary ischemia of the artery vascularization area. Spasm that occurs in these circumstances enhances the above abnormalities. Comparatively rapid regression of neurologic and above symptomatology was noted to occur in those HI patients demonstrating the following DS criteria: 1) location of moderate acceleration of cerebral venous outflow in the projection of ICH or straight brain sinus; 2) absence of cerebral artery compression and preservation of adequate blood-flow in the arteries of the base of the brain.
