A patient with a giant partially thrombosed basilar apex aneurysm was treated with balloon-assisted coil embolization. At the conclusion of the embolization, an Enterprise stent was placed from the upper basilar artery to the left P1 segment. Follow-up angiography 4 months later showed that the distal stent had pulled out of the posterior cerebral artery and was in the coil mass within the aneurysm. Angiography clearly showed that the stent had migrated down the basilar artery and that the artery was now kinked proximal to the stent. Nonetheless, the left posterior cerebral artery and the basilar artery were still widely patent. This is the first documented case in which a stent 'compacted' into a completed coiled aneurysm in a delayed fashion.
一位患有巨大部分血栓形成基底尖动脉瘤的患者接受了球囊辅助线圈栓塞治疗。在栓塞结束时，从上基底动脉到左 P1 段放置了 Enterprise 支架。4 个月后的随访血管造影显示，远端支架已从大脑后动脉脱出，位于动脉瘤内的线圈团块中。血管造影清楚地显示支架已经向基底动脉下移，并且支架近端的动脉发生了扭曲。尽管如此，左大脑后动脉和基底动脉仍然广泛通畅。这是首例支架以延迟方式“压缩”入已完成的线圈栓塞动脉瘤的病例。
