title: [Precursors of brain ischemia in patients in the acute stage of subarachnoid hemorrhage after the aneurysm rupture].
abstract: The authors attempted to predict an outcome of the disease using the dynamic evaluation of quantitative parameters of intracranial pressure (ICP) and linear systolic blood flow velocity (LSBFV). Seventeen patients, aged from 20 to 61 years, with acute subarachnoid hemorrhage (SAH) after the aneurysm rupture complicated with the syndrome of intracranial hypertension (SIH) and angiospasm were studied. A comparison of the clinical course and outcomes (good or bad) with corresponding quantitative parameters allows to conclude that the decrease in LSBFV (<200 cm/sec) in the syndrome of intracranial hypertension (ICP>30 mmHg) predicts the ischemic damage. LSBFV values higher than 200 cm/sec and ICP<30 mmHg reduces the risk for brain ischemia.
