Fusiform aneurysms are uncommon compared with their saccular counterparts, yet they remain very challenging to treat and are associated with high rates of rebleeding and morbidity. Lack of a true aneurysm neck renders simple clip reconstruction or coil embolization usually impossible, and more advanced techniques are required, including bypass, stent-assisted coiling, and, more recently, flow diversion. In this article, the authors review posterior circulation fusiform aneurysms, including pathogenesis, natural history, and endovascular treatment, including the role of flow diversion. In addition, the authors propose an algorithm for treatment based on their practice.
与囊状动脉瘤相比，梭形动脉瘤并不常见，但治疗起来仍然极具挑战性，且再出血率和发病率很高。由于缺乏真正的动脉瘤颈，通常无法进行简单的夹闭重建或弹簧圈栓塞，需要更先进的技术，包括搭桥、支架辅助弹簧圈栓塞，以及最近出现的血流导向术。在本文中，作者回顾了后循环梭形动脉瘤，包括其发病机制、自然病程和血管内治疗，包括血流导向术的作用。此外，作者根据自己的实践提出了一种治疗算法。
