More recently, the Barrow Ruptured Aneurysm Trial (BRAT), which included 358 patients, demonstrated superior functional outcome at 1 year with endovascular coil embolization than with microsurgical clipping for acutely ruptured intracerebral aneurysm. Further, in contrast to the ISAT results, no patient in the endovascular embolization group suffered a recurrent hemorrhage. [53] Outcomes at 3-year follow-up of the BRAT patients continued to favor coil embolization, though the difference no longer reached statistical significance. [54]
