Wide neck basilar tip aneurysms are challenging to secure with coil embosurgery despite balloon remodeling and stent-assisted coiling. In patients with favorable posterior circle of Willis anatomy, the traditional antegrade placement of two stents that span the basilar apex to both proximal posterior cerebral arteries (P1s) can be avoided by implanting a single stent across the P1s and basilar apex via a retrograde posterior communicating artery approach. This case report details the first use of the high radial force Wingspan stent placed in this fashion during basilar aneurysm coiling repair.
宽颈基底动脉尖部动脉瘤即使采用球囊重塑和支架辅助弹簧圈栓塞术，用弹簧圈栓塞治疗来确保安全也具有挑战性。对于 Willis 环后部解剖结构良好的患者，通过经后交通动脉逆行途径在 P1 段和基底动脉尖部植入单个支架，可避免传统的在基底动脉尖部至双侧大脑后动脉近端（P1 段）横跨两个支架的顺行放置方式。本病例报告详细介绍了在基底动脉瘤弹簧圈栓塞修复过程中首次以这种方式使用高径向力 Wingspan 支架。
