title: Clipping Surgery for Unruptured Middle Cerebral Artery Aneurysms.
abstract: Clipping surgeries for 139 consecutive unruptured middle cerebral aneurysms were performed between April 1991 and March 2014. Left hemiparesis occurred in one case (0.7 %). Transient symptoms arose in six patients due to perforator injury, arterial branch occlusion, damage to the venous system, or chronic subdural hematoma. Neither mortality nor decline in cognitive function was noted in this study. Clipping surgery for unruptured middle cerebral artery aneurysms can be done with minimal morbidity. However, meticulous management during the perioperative period as well as the use of modern technologies during the surgery, such as MEP monitoring and ICG videoangiography, are needed for safe and secure clipping surgery.
