[Intraventricular and intracerebral hemorrhage as complication of hemodynamic therapy for vasospasm after subarachnoid hemorrhage--analysis of 2 cases].

Intraventricular and intracerebral hemorrhage were observed in two patients (36-year-old male and 45-year-old female) whose ischemic deficits from vasospasm after subarachnoid hemorrhage due to ruptured aneurysm were treated or prevented with hemodynamic therapy. Both patients had a long history of arterial hypertension and showed high values of urinary catecholamine after subarachnoid hemorrhage. The cause of hemorrhage seemed to be the induced hypertension and the volume expansion in one case and the uncontrolled hypertension and the volume expansion in the other case. Although two patients were treated with the volume expansion therapy continuously after hemorrhage, neurological status deteriorated due to infarction caused by vasospasm. We discussed the limit and risk of hemodynamic therapy for patients who had a long history of arterial hypertension and increased catecholamine release after subarachnoid hemorrhage.
