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.
