The mortality and disability rate of patients with ruptured anterior communicating artery (AComA) aneurysm after bleeding is high. Even with the most advanced treatment methods, the incidence of complications remains high. The purpose of the present study was to determine the efficacy of microsurgery via supraorbital eyebrow keyhole approach (SOEK) in clipping ruptured AComA aneurysms. Between September 2010 and October 2018, 543 patients with intracranial aneurysms were admitted to the Department of Neurosurgery of the Third Affiliated Hospital of Sun Yat-Sen University (Guangzhou, China). Among them, 85 patients with ruptured AComA aneurysm and subarachnoid hemorrhage (SAH) underwent microsurgical clipping via the SOEK approach. In those patients, the clipping rate, complications and clinical efficacy of treatment were evaluated. The average age of the patients was 52.69±9.94 years (range, 28-78 years). The proportions of small, medium and large aneurysms were 83.5, 15.3 and 1.2%, respectively. Procedural complications occurred in 9 cases (10.5%). The occlusion rate of the aneurysms was 98.8%. The average follow-up period was 37.9 (±24.5) months. A total of 81.2% of the patients with SAH had a good clinical prognosisat 1 year (modified Rankin scale score, ≤2). In conclusion, for a skilled and experienced surgeon, SOEK was indicated to be a safe procedure for the treatment of ruptured AComA aneurysms; it provided sufficient intra-operative exposure and a high clipping rate.
