A Correlative Study of Cerebral Hemodynamic Charge and Blood Pressure in Acute Spontaneous Intracerebral Hemorrhage

Objective To investigate the cerebral hemodynamic abnormal patter and its regularity of dynamic charge,and the correlation with abnormality of blood pressure(Bp) on acute stage of spontaneous intracerebral hemorrhage(SICH) patients by transcranial Doppler(TCD).Methods 54 patients with acute SICH were studied.All patients were dynamic evaluated by beside TCD and 24h ambulatory blood pressure monitoring(ABPM) on the 1st,7th,21st day.Results On the 1st day the TCD abnormity occurred mainly in the anterior circulation of cerebrum,which the cardinal manifestation was high-resistance,low-flow velocity blood waveforms,especially the bleeding side.And the bilateral cerebral blood flow were significantly asymmetrical.Continuous TCD monitoring revealed that,the low velocity of the cerebral blood flow increased,meanwhile the high value of PI decreased gradually,the TCD monitoring was within the normal range three weeks after the atttack.The 24-hour′s mean systolic blood pressure had negative correlation with the mean cerebral velocities of middle cerebral arteries,positive correlation with the PI value.Conclusion The TCD examination can be used to monitor the cerebral hemodynamics of the patients suffering from intracerebral hemorrhage,and provide useful references to the antihypertension management.
