A woman presented with 75% stenosis of the right internal carotid artery (ICA) with extension to the origin of a persistent hypoglossal artery (PHA). The PHA is a rare fetal variant of carotid-basilar anastomosis that elevates the risk of ischemia and embolic infarction within the posterior cerebral circulation in patients with carotid disease proximal to the anastomosis. Our case is highly unique because of the extremely rare nature of the PHA with associated ICA stenosis that extended to the PHA. Additionally, a novel treatment approach was employed by stenting and angioplasty while protecting both the anterior and posterior cerebral circulations.
一名女性患者出现右侧颈内动脉（ICA）75%狭窄，并延伸至永存舌下动脉（PHA）起始处。PHA是一种罕见的颈动脉-基底动脉吻合的胎儿期变异，会增加吻合口近端患有颈动脉疾病的患者后循环缺血和栓塞性梗死的风险。我们的病例非常独特，因为PHA合并ICA狭窄并延伸至PHA极为罕见。此外，我们采用了一种新颖的治疗方法，即支架置入术和血管成形术，同时保护前、后循环。
