BACKGROUND
Aneurysms of the anterior inferior cerebellar artery (AICA), especially those located in the distal portion of the AICA, are rare. There are few reported cases treated with surgery or endovascular embolization.
CASE DESCRIPTION
We report two cases of fusiform distal AICA aneurysms presenting with subarachnoid hemorrhage. Parent artery occlusion with coils and n-butyl cyanoacrilate (n-BCA) resulted in complete aneurysm occlusion and prevented rebleeding. Both patients presented postprocedure neurological deficits, but have made a good recovery at 4 and 10 months, respectively.
CONCLUSION
Occlusion of the parent artery for the treatment of ruptured fusiform distal AICA aneurysms is effective but has significant neurological risks.
背景
小脑前下动脉（AICA）动脉瘤，尤其是位于AICA远端的动脉瘤，较为罕见。鲜有采用手术或血管内栓塞治疗的病例报道。
病例描述
我们报告两例梭形AICA远端动脉瘤伴蛛网膜下腔出血的病例。采用弹簧圈和正丁基氰基丙烯酸酯（n-BCA）闭塞载瘤动脉，实现了动脉瘤的完全闭塞，防止了再出血。两名患者术后均出现神经功能缺损，但分别在4个月和10个月时恢复良好。
结论
闭塞载瘤动脉治疗破裂的梭形AICA远端动脉瘤有效，但存在显著的神经风险。
