Orbitozygomatic Craniotomy for Clipping a Complex Middle Cerebral Artery Aneurysm: 2-Dimensional Operative Video.
Middle cerebral artery (MCA) aneurysms pose a surgical challenge because of the large caliber of the parent artery and the common need to dissect the sylvian fissure to permit access to the proximal and distal control. The neck of the aneurysm should be generously dissected to permit visualization of any adjacent lenticulostriate perforators. This patient demonstrated a left-sided wide-necked bilobed MCA aneurysm at the M1 bifurcation. The aneurysm was approached using a left orbitozygomatic craniotomy with distal sylvian fissure dissection. A single curved clip was applied for aneurysm occlusion, and postoperative angiography demonstrated aneurysm obliteration with parent vessel patency. The patient gave informed consent for surgery and video recording. Institutional review board approval was deemed unnecessary.
