5. Study Description

Brief Summary
The investigators seek to demonstrate that the combined use of cilostazol and nimodipine will significantly decrease the rate of delayed cerebral infarction and cerebral vasospasm after cerebrovascular intervention when compared to nimodipine alone.
Detailed Description
This research study is for people who have a brain hemorrhage, due to a ruptured aneurysm. Adding the drug cilostazol to the standard care may improve outcomes after surgery. The blood within the brain following aneurysmal hemorrhage can have harmful effects on the blood vessels causing them to narrow and thus decrease blood flow; this process is called vasospasm. Decreased blood flow in the brain can lead to more damage. Delayed cerebral ischemia is a complication which is believed to be a consequence of reduced blood flow to the brain following this type of hemorrhage. Cilostazol opens blood vessels and reduces the formation of blood clots. The standard treatment of these hemorrhages currently involves the use of nimodipine which also relaxes blood vessels and allows blood to flow more freely. The combination of these two drugs cilostazol and nimodipine may improve neurologic outcomes after surgery.
