Study Description
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.

Condition or disease Intervention/treatment
Ruptured Cerebral Aneurysm Subarachnoid Hemorrhage (SAH) Procedure: coil embolization Procedure: clip occlusion

Detailed Description:
The planned trial enrolled 250 subjects per arm. Subjects are followed postoperatively and outcome endpoints will be assessed at Discharge, 6 Months, 1 Year, 3 Years, and 6 Years. One hundred (100) subjects will participate in neuropsychological testing at 1 Year; after the 100th subject an interim data analysis will be performed and the viability of future neuropsychological testing will be determined. Subjects will receive preoperative, intraoperative or postoperative, 3 Year follow up, and 6 Year follow up angiograms. In this fashion immediate clinical outcome, including peri-procedural morbidity and mortality, will be assessed as will long term outcome, both clinical and angiographic.

Arms and Interventions

Arm Intervention/treatment
Active Comparator: Endovascular
Subjects 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.
Procedure: coil embolization
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.
Active Comparator: Surgical
Subjects randomized to surgical clip occlusion repair will receive treatment from one of two neurosurgeons expert in clip occlusion surgery for ruptured aneurysms.
Procedure: clip occlusion
Subjects randomized to surgical therapy will receive treatment from one of two neurosurgeons expert in surgery for ruptured aneurysms.

Outcome Measures

Primary Outcome Measures :
  1. Modified Rankin Scale [ Time Frame: 10 years ]
    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.
