Stent-assisted coil embolization (SACE) is useful for treating wide-necked aneurysms. Most superior cerebellar artery (SCA) aneurysms have a wide neck, but there are few reports of SCA aneurysms treated with SACE. One reason is that the anatomical characteristic of SCA aneurysm is not suitable for standard SACE. It is often challenging to deliver a stent to SCA via the basilar artery in an anterograde manner. In contrast, it is not difficult to deliver a stent to SCA from the anterior circulation via the posterior communicating artery. This method, in which a catheter is navigated from the anterior to the posterior circulation, is called a transcirculation technique. We report two cases of SCA aneurysm successfully treated with SACE using transcirculation technique. This approach is helpful for wide-necked SCA aneurysms.
支架辅助弹簧圈栓塞术（SACE）对于治疗宽颈动脉瘤很有用。大多数小脑上动脉（SCA）动脉瘤具有宽颈，但关于用SACE治疗SCA动脉瘤的报道很少。一个原因是SCA动脉瘤的解剖特征不适合标准的SACE。经基底动脉以顺行方式将支架输送至SCA通常具有挑战性。相比之下，从颈内动脉通过后交通动脉将支架输送至SCA并不困难。这种将导管从颈内动脉循环导航至后循环的方法称为跨循环技术。我们报告了2例使用跨循环技术经SACE成功治疗的SCA动脉瘤病例。这种方法对宽颈SCA动脉瘤很有帮助。
