Persistence of the hypoglossal artery into adulthood is a rare vascular anomaly and, when present, provides the predominant vascular supply to the posterior circulation. We describe a case of vertebrobasilar insufficiency associated with severe high-grade stenosis of the persistent hypoglossal artery and tandem stenosis of the proximal ipsilateral internal carotid artery, treated by an endovascular approach. The unique anatomical and technical challenges associated with this case are reviewed in detail.
舌下动脉持续存在至成年是一种罕见的血管异常，当存在时，它为后循环提供主要的血管供应。我们描述了一例与持续性舌下动脉严重高分级狭窄和同侧近端颈内动脉串联狭窄相关的椎基底动脉不足的病例，采用血管内方法治疗。详细回顾了与该病例相关的独特解剖和技术挑战。
