The persistent primitive hypoglossal artery (PPHA) is a rare fetal variant of carotid-basilar anastomosis that increases the risk of ischemia and embolic infarction within the posterior cerebral circulation in patients with carotid stenosis proximal to the origin of the PPHA. A man presented with severe stenosis of the right internal carotid artery with extension to the origin of a PPHA. The area of stenosis was at a high position, which contraindicated carotid endarterectomy. Therefore, stenting was performed with proximal reversal of flow embolic protection. The unique anatomic and technical challenges associated with this case are reviewed in detail.
永存原始舌下动脉（PPHA）是一种罕见的胎儿期颈动脉 - 基底动脉吻合变异，在PPHA起源近端存在颈动脉狭窄的患者中，会增加大脑后循环缺血和栓塞性梗死的风险。一名男性患者出现右颈内动脉严重狭窄并延伸至PPHA起源处。狭窄部位较高，这使得颈动脉内膜切除术成为禁忌。因此，采用近端血流逆转式栓塞保护装置进行了支架置入术。本文详细回顾了与该病例相关的独特解剖学和技术挑战。
