The stent-assisted coiling technique has expanded the applicability of endovascular treatment for wide-neck intracranial aneurysms. However, the stability of the deployed stent has been questioned. We present this case to demonstrate intraprocedural migration of the deployed stent and subsequent management.
A 59-year-old female patient presented with dizziness and fatigue. Imaging, including CT and MR angiography, revealed a 7×6.5 mm wide-neck basilar tip aneurysm.
Stent-assisted coiling was attempted. After deployment of the stent, the distal portion of the stent migrated into the aneurysm sac, and then stabilized. Since attempted coiling without an assistance device was unsuccessful, the balloon-assisted coiling technique was applied. Near-total obliteration of the basilar tip aneurysm was accomplished.
The stability of a deployed stent should be confirmed to exclude the possibility of intraprocedural stent migration. If stent migration into the target aneurysm occurs, the balloon-assisted coiling technique through the deployed stent is a feasible and valuable tool for successful coil embolization.
支架辅助弹簧圈技术拓宽了血管内治疗宽颈颅内动脉瘤的适应证。然而，支架的稳定性一直存在疑问。我们在此报告一例术中支架移位的病例，并展示其后续处理。
一名 59 岁女性因头晕和乏力就诊。包括 CT 和 MR 血管造影在内的影像学检查显示基底尖部 7×6.5mm 宽颈动脉瘤。
尝试支架辅助弹簧圈栓塞。支架释放后，支架的远端部分向动脉瘤囊内移位，随后稳定下来。由于未使用辅助装置进行尝试性弹簧圈栓塞不成功，因此应用了球囊辅助弹簧圈技术。基底尖部动脉瘤基本完全闭塞。
应确认已释放支架的稳定性，以排除术中支架移位的可能性。如果支架向目标动脉瘤内移位，通过已释放的支架行球囊辅助弹簧圈技术是一种可行且有价值的工具，有助于实现成功的线圈栓塞。
