OBJECTIVE
Cerebral aneurysms (ANs) in the cortical segment (CS) of the distal posterior inferior cerebellar artery (PICA) with a vertebral artery (VA) of aortic origin are markedly rare. Endovascular therapy was performed to treat subarachnoid hemorrhage caused by a ruptured cerebral AN.
CASE PRESENTATION
The patient was a 68-year-old female who was transported to emergency care for headache. Detailed examination revealed an AN in the CS of the PICA with a left VA of distal aortic origin from the left subclavian artery (LT. SA). Endovascular therapy using n-butyl-2-cyanoacrylate (NBCA) was performed to treat the cerebral AN, resulting in a favorable outcome.
CONCLUSION
Endovascular therapy for cerebral ANs is an effective treatment method.
目的
起源于主动脉的椎动脉（VA）走行的小脑后下动脉（PICA）远侧皮质段（CS）的脑动脉瘤（ANs）极为罕见。对破裂脑动脉瘤引起的蛛网膜下腔出血进行了血管内治疗。
病例介绍
患者为一名68岁女性，因头痛被送往急诊。详细检查发现PICA的CS段有一个动脉瘤，其左侧椎动脉起源于左锁骨下动脉（LT.SA）的主动脉远侧段。采用正丁基-2-氰基丙烯酸酯（NBCA）进行血管内治疗脑动脉瘤，结果良好。
结论
脑动脉瘤的血管内治疗是一种有效的治疗方法。
