The posterior cerebral artery (PCA) is divided into 4 segments: precommunicating segment (P1), postcommunicating segment (P2), quadrigeminal segment (P3), and calcarine segment (P4). Small aneurysms are more prevalent than large aneurysms in patients with ruptured aneurysms. P2 and P3 aneurysms are usually managed by the subtemporal approach. This is a case report of rupture saccular aneurysm of posterior cerebral artery on P2P segment. The authors show the surgical steps of these rare aneurysms with an illustrative case.
大脑后动脉（PCA）分为4段：交通前段（P1）、交通后段（P2）、四叠体段（P3）和距状沟段（P4）。在动脉瘤破裂患者中，小动脉瘤比大动脉瘤更常见。P2和P3段动脉瘤通常采用颞下入路进行治疗。本文报告1例大脑后动脉P2P段破裂囊状动脉瘤的病例。作者通过1例说明性病例展示了这些罕见动脉瘤的手术步骤。
