Objective. To describe asymptomatic delayed migration of a coil loop in a patient following successful coil embolization of an anterior communicating artery saccular aneurysm. Methods. A 24-year-old man with a ruptured anterior communicating artery saccular aneurysm underwent coil embolization with one helical ultrasoft coil. Results. A followup CT scan head and a cerebral angiogram one month following the procedure revealed distal migration of an intra-aneurysmal coil loop into the left pericallosal artery. The patient, however, remained asymptomatic. Conclusion. Delayed migration of coil following embolization of an intracranial aneurysm is an extremely rare occurrence. An asymptomatic presentation, as in our patient, is even more unique. The stent-like configuration of the migrated spiral coil loop probably prevented complete occlusion of the blood vessel.
目的。描述一名前交通动脉囊状动脉瘤成功进行弹簧圈栓塞术后患者弹簧圈环的无症状延迟移位情况。方法。一名患有破裂前交通动脉囊状动脉瘤的24岁男性接受了单根螺旋超软弹簧圈栓塞治疗。结果。术后1个月的头颅随访CT扫描和脑血管造影显示动脉瘤内的弹簧圈环向左侧胼周动脉远端移位。然而，患者仍无症状。结论。颅内动脉瘤栓塞后弹簧圈延迟移位极为罕见。像我们的患者这样无症状的表现更为独特。移位的螺旋弹簧圈环的支架样结构可能阻止了血管的完全闭塞。
