BACKGROUND
Arteries that anastomose with the posterior inferior cerebellar artery (PICA) can harbor aneurysms.
CASE DESCRIPTION
We present a case of a patient who suffered a subarachnoid hemorrhage as a result from an aneurysm on the left lateral spinal artery (LSA) that anastomosed to the PICA. The aneurysm was treated surgically, and the flow between the LSA and PICA was disrupted. The activated anastomotic network created a new anastomosis between the LSA and PICA, which was seen at 6 months' follow-up.
CONCLUSIONS
Careful follow-up is warranted in patients who have an activated anastomotic network because they can potentially develop aneurysms on newly created anastomoses.
背景
与小脑后下动脉（PICA）吻合的动脉可能存在动脉瘤。
病例描述
我们报告一例患者，其因与PICA吻合的左侧脊髓外侧动脉（LSA）上的动脉瘤而发生蛛网膜下腔出血。该动脉瘤接受了手术治疗，LSA与PICA之间的血流被中断。激活的吻合网络在LSA与PICA之间形成了新的吻合，这在6个月的随访中可见。
结论
对于有激活吻合网络的患者，需要进行仔细随访，因为他们可能在新形成的吻合处发生动脉瘤。
