The hypoglossal artery is present as an anastomotic channel between the carotid and vertebrobasilar system for approximately one week during embryologic development. Rarely, it may persist into adulthood and may be encountered during cerebrovascular operations. We report a 76-year-old woman with a persistent hypoglossal artery and a symptomatic internal carotid stenosis treated successfully by carotid endarterectomy. A discussion of the embryology, radiology, and operative pitfalls follows.
舌下动脉在胚胎发育过程中作为颈动脉和椎基底动脉系统之间的吻合通道存在约一周时间。很少见的情况下，它可能持续至成年期，在脑血管手术中可能会遇到。我们报告一例76岁女性，患有持续存在的舌下动脉和有症状的颈内动脉狭窄，通过颈动脉内膜切除术成功治疗。随后将对其胚胎学、放射学及手术陷阱进行讨论。
