Modern standards for prevention of vasospasm include the calcium channel-blocker, nimodipine,[36] and induced hypertension, hypervolemia and hemodilution therapy (HHHT).[3] These act to lessen smooth muscle spasm and maximize perfusion when spasm occurs.[3,22,37] These therapies improve outcome by up to 21%, and are especially effective for patients in good clinical condition on admission and thin clot on initial CT scan.[19] Despite the best therapy, the primary causes of death and disability continue to be the direct effect of the initial SAH and vasospasm.[5,21]
The incidence of intracranial bleeding, symptomatic vasospasm and neurologic outcome at 3 months were compared in the t-PA and placebo groups.[12] Although the overall incidence of vasospasm was similar between the groups, the results demonstrated a trend towards less severe vasospasm in the t-PA treated group, and a 56% relative risk reduction of severe vasospasm in patients with thick SAH who received the t-PA (p=0.02).[12] Other trends in the t-PA treated group were less use of HHHT, lower mean velocites on the transcranial Doppler (TCD) studies, reduced neurological worsening, lower 14 day mortality and improved 3-month outcomes (Tables 1, 2).
