Delayed cerebral arterial vasospasm is one of the leading causes of death and disability after aneurysmal subarachnoid hemorrhage (aSAH). We evaluated the safety of intraventricular nicardipine (IVN) for vasospasm (VSP) in aSAH patients, and outcomes compared with a control population.

IVN effects on VSP were evaluated by transcranial Doppler (TCD).
