支架辅助弹簧圈栓塞术后支架内狭窄是一种罕见但众所周知的并发症。1例32岁女性患者，左侧颈内动脉末端宽颈动脉瘤未破裂，同侧脉络膜前动脉极小动脉瘤，采用支架辅助弹簧圈栓塞治疗颈内动脉末端动脉瘤。术后4个月血管造影显示支架内弥漫性狭窄，未治疗的脉络膜前动脉瘤消失，保留了脉络膜前动脉的通畅。据我们所知，这是第一次报道支架内狭窄和未经治疗的颅内小动脉瘤消失的过程。我们报告了这一独特的病例，并讨论了这种现象背后有趣的机制，并对相关文献进行了回顾。
In-stent stenosis after stent-assisted coil embolization is a rare but well-known complication. A 32-year-old woman with an unruptured wide-necked left internal carotid artery (ICA) terminus aneurysm and an ipsilateral very small anterior choroidal artery aneurysm underwent stent-assisted coil embolization for the ICA terminus aneurysm. The 4-month follow-up angiography revealed diffuse in-stent stenosis and disappearance of the untreated anterior choroidal artery aneurysm, retaining the patency of the anterior choroidal artery. To our knowledge, this is the first report to demonstrate the course of in-stent stenosis and disappearance of an untreated small intracranial aneurysm as a result. We report this unique case and discuss the interesting mechanism underlying this phenomenon, and also provide a review of the relevant literature.
