Anterior communicating artery (ACoA) aneurysms can orient rostrally into the interhemispheric fissure or caudally into the optic chiasm. The majority of these aneurysms project into the interhemispheric fissure. This patient had an ACoA aneurysm with a multilobulated appearance, and the primary lobe projected into the interhemispheric fissure. The cisterns were opened sharply via an orbitozygomatic approach to permit proximal, distal, and neck control. A permanent clip was applied across the aneurysm neck and on a small contralateral aneurysm. Postoperative imaging confirmed complete aneurysm occlusion. The patient gave informed consent for surgery and video recording. Institutional review board approval was deemed unnecessary.

前交通动脉（ACoA）动脉瘤可向上延伸至大脑半球间裂，或向下延伸至视交叉。这些动脉瘤大多突入大脑半球间裂。该患者患有呈多叶状外观的前交通动脉动脉瘤，主要叶突入大脑半球间裂。通过眶颧入路锐性打开脑池，以实现近端、远端和瘤颈控制。在动脉瘤颈及一个小的对侧动脉瘤上应用永久性夹闭。术后影像学检查证实动脉瘤完全闭塞。患者已签署手术及录像知情同意书。机构审查委员会批准被认为不必要。经亚利桑那州凤凰城巴罗神经学研究所许可使用。
