Persistent primitive hypoglossal artery (PPHA) is often associated with intracranial anomalies such as aneurysms. Surgical treatment of aneurysms on the PPHA is challenging due to that the posterior circulation depends solely on PPHA.
A case of an 83-year-old woman with a large aneurysm on PPHA presented with vertigo was reported.
Three-dimensional angiogram revealed a wide-neck aneurysm on the PPHA.
The aneurysm was successfully treated using a novel low-profile visualized intraluminal support stent-assisted coiling technique.
No complications occurred during the procedure. The final angiogram confirmed the patency of the posterior inferior cerebellar artery and the parent artery and its distal branches.
Our case suggests that stent-assisted coil embolization is safe and effective for the treatment of aneurysms on the PPHA.
永存原始舌下动脉（PPHA）常与颅内动脉瘤等异常情况相关。由于后循环仅依赖于PPHA，因此对PPHA上的动脉瘤进行手术治疗具有挑战性。
报告了一例83岁患有PPHA上大动脉瘤且伴有眩晕的女性病例。
三维血管造影显示PPHA上有一个宽颈动脉瘤。
使用一种新型低轮廓可视化腔内支撑支架辅助弹簧圈栓塞技术成功治疗了该动脉瘤。
手术过程中未发生并发症。最终血管造影证实小脑后下动脉及其母动脉及其远端分支通畅。
我们的病例表明，支架辅助弹簧圈栓塞治疗PPHA上的动脉瘤是安全有效的。
