Abstract

Objective: A rare case of parent artery stenosis and visual disturbance after balloon-assisted coil embolization for an unruptured cerebral aneurysm is reported. Case Presentation: A 63-year-old woman underwent successful coil embolization of an incidental cerebral aneurysm using a balloon-assisted technique. The aneurysm was located in the right internal carotid artery. Her treatment course was uneventful, and she was discharged without any neurological deficits. Follow-up angiography after 9 months showed severe parent artery stenosis without aneurysm recurrence. However, she had a visual disturbance, and MRI showed edema around the treated aneurysm at the same time. Judging from the results of several metal patch tests, the platinum coils caused this pathology, and oral steroids and antihistamines were administered. This treatment improved her parent artery stenosis, but her visual disturbance persisted. Conclusion: Although parent artery stenosis after coil embolization using balloon-assisted technique of a cerebral aneurysm in the chronic phase is rare, we should consider the possibility of metal allergy.

球囊辅助螺旋栓塞治疗未破裂脑动脉瘤后载动脉狭窄及视力障碍1例

目的:报道一例罕见的未破裂脑动脉瘤球囊辅助血管栓塞术后伴载动脉狭窄及视力障碍的病例。病例介绍:一名63岁的女性采用球囊辅助技术成功地栓塞了偶然发生的脑动脉瘤。动脉瘤位于右侧颈内动脉。她的治疗过程很顺利，出院时没有任何神经缺陷。9个月后的随访血管造影显示严重的载动脉狭窄，无动脉瘤复发。然而，她有视觉障碍，同时MRI显示动脉瘤周围水肿。从几次金属贴片试验的结果来看，铂线圈引起了这种病理，口服类固醇和抗组胺药。这种治疗改善了她的母动脉狭窄，但她的视力障碍仍然存在。结论:采用球囊辅助技术对脑动脉瘤进行螺旋栓塞后出现载动脉狭窄的情况在慢性期较为少见，但仍应考虑金属过敏的可能性。
