A 76-year-old female presented with vertebrobasilar insufficiency due to a severe stenosis of the right primitive hypoglossal artery (an unusual carotid-basilar anastomosis) manifesting as recurrent transient ischemic attacks (TIA) associated with quadriparesis and cerebellar ataxia with vertigo, nausea, and vomiting. She had been treated with 100 mg of aspirin per day, but TIA associated with the same symptoms persisted. Cerebral blood flow (CBF) studies disclosed a region of moderately low flow in the posterior fossa. Cerebral angiography demonstrated that the posterior fossa was supplied via the right primitive hypoglossal artery, which was severely stenotic at its origin. Percutaneous transluminal angioplasty using a Stealth catheter, 3.0-mm diameter and 10-mm long, successfully dilated the stenosis. No TIA occurred postoperatively, and a marked increase in CBF was demonstrated in the posterior fossa.
一名76岁女性因右侧原始舌下动脉（一种不常见的颈基底吻合）严重狭窄出现椎基底动脉供血不足，表现为反复发作的短暂性脑缺血发作（TIA），伴有四肢瘫痪及小脑性共济失调，伴有眩晕、恶心和呕吐。她每日服用100毫克阿司匹林治疗，但伴有相同症状的TIA仍持续存在。脑血流（CBF）研究显示后颅窝有一中等低血流区域。脑血管造影显示后颅窝由右侧原始舌下动脉供血，该动脉起始处严重狭窄。使用直径3.0毫米、长10毫米的Stealth导管进行经皮腔内血管成形术成功扩张了狭窄部位。术后未再发生TIA，且后颅窝CBF显著增加。
