Posterior inferior cerebellar artery (PICA) aneurysms pose significant surgical challenges. The authors present a novel bypass technique involving distal PICA displacement and end-to-side anastomosis to the contralateral PICA.
The authors describe a successful case in which the distal PICA was relocated, followed by an end-to-side anastomosis to the contralateral PICA, effectively bypassing the aneurysm and restoring normal blood flow.
This innovative approach highlights the potential of bypass surgery for PICA aneurysms, particularly when traditional endovascular methods are unsuitable. Individual anatomical considerations are crucial for effective treatment planning. https://thejns.org/doi/10.3171/CASE24741.
小脑后下动脉（PICA）动脉瘤带来了重大的手术挑战。作者介绍了一种新颖的搭桥技术，该技术涉及PICA远端移位并与对侧PICA进行端侧吻合。
作者描述了一例成功的病例，其中PICA远端被重新定位，随后与对侧PICA进行端侧吻合，有效地绕过了动脉瘤并恢复了正常血流。
这种创新方法凸显了针对PICA动脉瘤进行搭桥手术的潜力，尤其是在传统血管内方法不适用时。个体解剖学因素对于有效的治疗规划至关重要。https://thejns.org/doi/10.3171/CASE24741
