Internal carotid artery (ICA) agenesis is a rare vascular anomaly that, in combination with occlusion of the contralateral ICA, produces significant strain on the posterior circulation for collateral flow. We report a patient who presented with transient ischemic attack and was found to have congenital ICA agenesis and contralateral ICA occlusion with cerebral perfusion maintained through dilated vertebrobasilar circulation.
颈内动脉发育不全是一种罕见的血管异常，与对侧颈内动脉闭塞相结合，会对后循环的侧支血流产生显著压力。我们报告了一名出现短暂性脑缺血发作的患者，发现其患有先天性颈内动脉发育不全和对侧颈内动脉闭塞，通过扩张的椎基底循环维持脑灌注。
