使用可解脱弹簧圈进行血管内治疗后，特别是治疗后数月，弹簧圈延迟移位极为罕见。在本报告中，作者描述了1例77岁女性患者，在无并发症的动脉瘤栓塞后3个月发生弹簧圈延迟移位至大脑前动脉和后交通动脉（PCoA）。患者使用闭孔支架成功再次治疗。计算流体动力学（CFD）显示初始治疗动脉瘤的残余腔内存在高壁面剪切应力（WSS）和多个漩涡。计算流体动力学可能有助于检测和预测这种并发症，支架辅助技术可能是一种重要的治疗选择。
Delayed coil migration after endovascular treatment with detachable coils, particularly several months after treatment, is extremely rare. In this report, the authors describe a 77-year-old female in whom delayed coil migration to the anterior cerebral artery and posterior communicating artery (PCoA) developed 3 months after an uncomplicated aneurysm embolization. The patient was successfully retreated with a closed-cell stent. Computational fluid dynamics (CFD) revealed high wall shear stress (WSS) and multiple vortices in the residual cavity of the initially treated aneurysm. CFD could be useful to detect and predict this complication, and a stent-assisted technique could be an important treatment option.
