  • Title: Orbitozygomatic Craniotomy for Giant Anterior Communicating Artery Aneurysm: 2-Dimensional Operative Video.
    Author: Hendricks BK, Spetzler RF.
    Journal: Oper Neurosurg (Hagerstown); 2020 Jan 01; 18(1):E5-E6. PubMed ID: 31758183.
    Abstract:
    Giant intracranial aneurysms pose a significant surgical challenge because of the associated difficulty in achieving adequate visualization of the parent artery and aneurysm neck. This patient had an incidentally identified giant anterior communicating artery aneurysm. An orbitozygomatic craniotomy was performed for aneurysm exposure and aneurysmal neck dissection. Aneurysm dome opening and thrombectomy was performed to debulk the aneurysmal mass, which facilitated subsequent aneurysmal neck visualization. Sequential utilization of temporary clips of the bilateral A1 and bilateral A2 vessels reduced hemorrhage during thrombectomy. Multiple permanent clips were applied along the dissected aneurysm neck to permit occlusion. A small fracture of the aneurysm neck was identified, and cotton was applied with subsequent tamponade utilizing a fenestrated clip to maintain hemostasis. Indocyanine green fluoroscopy was used to verify parent and distant vessel patency. The patient gave informed consent for surgery and video recording. Institutional review board approval was deemed unnecessary. Used with permission from Barrow Neurological Institute, Phoenix, Arizona.
