====== Cerebral Vasospasm Prevention ======
Cerebral vasospasm and the resulting infarction remain the most devastating complications of aneurysmal subarachnoid hemorrhage (aSAH). 

Since vasodilator drugs cannot reverse cerebral vasospasm, treatment is directed to prevent vasospasm and to prevent or reverse ischemic deficits
((Levati A, Solaini C, Boselli L. Prevention and treatment of vasospasm. J Neurosurg Sci. 1998 Mar;42(1 Suppl 1):27-31. PMID: 9800599.)).
