Brief Summary
With evolving endovascular technologies there is a growing debate centered on the relative safety and efficacy of the currently accepted alternatives for the treatment of ruptured cerebral aneurysms in the face of acute subarachnoid hemorrhage (SAH). The purpose of this study is to compare the safety and efficacy of microsurgical clipping and endovascular coiling of acutely ruptured cerebral aneurysms in a prospective, randomized fashion.

Outcome Measures
Primary Outcomes (1)
Modified Rankin Scale
Primary Outcome Measure is Modified Rankin Scale \< or = to 2. Data will be analyzed on intent to treat basis with crossover to the alternative treatment analyzed as a data subset. The null hypothesis is that no difference in outcome will be detected between the endovascular and surgical treatment arms. A statistically significant difference will then be considered evidence in favor of the alternative hypothesis, that one treatment is superior to the other.

Study Arms (2)
Endovascular
ACTIVE COMPARATORSubjects randomized to endovascular coil embolization will be treated by one of two neurosurgeons expert in such treatment. All endovascular coil embolization treatments will be accomplished using accepted techniques.
Surgical
ACTIVE COMPARATORSubjects randomized to surgical clip occlusion repair will receive treatment from one of two neurosurgeons expert in clip occlusion surgery for ruptured aneurysms.
Interventions
Subjects randomized to endovascular therapy will be treated by one of two neurosurgeons expert in such treatment. All endovascular treatments will be accomplished using accepted techniques.
Subjects randomized to surgical therapy will receive treatment from one of two neurosurgeons expert in surgery for ruptured aneurysms.
