Analysis of supplemental surgical or endovascular treatment for cerebral aneurysms in the endovascular performed cases

In the 150 endovascular performed cases from May 1997 to Dec 2004, supplemental combination of endovascular and surgical treatments were performed in 46 cases. Characteristics of the treatments were combination for multiple aneurysms, surgical clipping for failed endovascular attempt, embolization for recurrence after clipping, bypass surgery before endovascular parent artery occlusion, surgery for recurrent aneurysms after embolization, and embolization for failed surgical attempt. Sixty seven percent of ruptured and 87% of unruptured cases showed satisfactory clinical outcome (modified Rankin scale = 0 to 2). Supplemental combination of each treatment will support the disadvantage of another treatment, and which improve the clinical outcome of cerebral aneurysm.
