Long-term results of middle cerebral artery aneurysm clipping in the Barrow Ruptured Aneurysm Trial

Restricted access


In Brief

Microsurgical clipping has withstood the test of time as a safe, effective, and durable treatment for ruptured middle cerebral artery (MCA) aneurysms. With continued advances in endovascular techniques, reports of endovascular treatment of ruptured MCA aneurysms are increasing. The authors report detailed outcomes of microsurgical clipping of MCA aneurysms from the Barrow Ruptured Aneurysm Trial. These results should serve as a benchmark for future studies examining endovascular management of these patients.

ABBREVIATIONS BRAT = Barrow Ruptured Aneurysm Trial; GCS = Glasgow Coma Scale; GOS = Glasgow Outcome Scale; IPH = intraparenchymal hemorrhage; IVH = intraventricular hemorrhage; MCA = middle cerebral artery; mRS = modified Rankin Scale; SAH = subarachnoid hemorrhage.
