OBJECTIVE
We report a case of ruptured aneurysm at the anterior pontine segment of the anterior inferior cerebellar artery (AICA) which re-ruptured after stent placement and was treated by overlapping stenting.
CASE PRESENTATION
A 53-year-old woman presented with headache. CT demonstrated subarachnoid hemorrhage. DSA revealed no evident source of bleeding. On day 10, she complained of sudden headache and CT demonstrated re-bleeding. On repeated DSA, an aneurysm at the anterior pontine segment of the right AICA was found. An LVIS Jr. stent was deployed at the right AICA including the aneurysm. On postoperative day 23, the aneurysm ruptured again. Another LVIS Jr. stent was deployed at the same area. On day 56, she was discharged home without neurological deficit.
CONCLUSION
Intracranial aneurysms not indicated for coil embolization or parent artery occlusion are difficult to treat. Overlapping stenting may be a treatment option for such aneurysms.
目的
我们报告一例小脑前下动脉（AICA）脑桥前段动脉瘤破裂病例，该动脉瘤在支架置入后再次破裂，并通过重叠支架置入术进行治疗。
病例介绍
一名53岁女性因头痛就诊。CT显示蛛网膜下腔出血。数字减影血管造影（DSA）未发现明显出血源。第10天，她突发头痛，CT显示再次出血。再次行DSA检查时，发现右侧AICA脑桥前段有一个动脉瘤。在右侧AICA包括动脉瘤处植入一枚LVIS Jr.支架。术后第23天，动脉瘤再次破裂。在同一区域又植入一枚LVIS Jr.支架。第56天，她出院回家，无神经功能缺损。
结论
对于不适合进行弹簧圈栓塞或载瘤动脉闭塞的颅内动脉瘤，治疗困难。重叠支架置入术可能是治疗此类动脉瘤的一种选择。
