We report a rare case of agenesis of the left internal carotid artery (ICA) and an aortic arch anomaly that presented with ipsilateral congenital Horner's syndrome. Digital subtraction angiography revealed left ICA agenesis shortly after its origin and anastomosis between the left maxillary artery and the supraclinoid segment of the left ICA. Aortography of the aortic arch revealed the right subclavian artery arising as the first branch of a left aortic arch, followed by a bicarotid trunk and a left subclavian artery. High resolution CT of the skull base revealed the absence of the left carotid channel, consistent with congenital agenesis of the ICA.
我们报告一例罕见的左侧颈内动脉(ICA)缺如并伴有主动脉弓异常的病例,该病例表现为同侧先天性霍纳综合征。数字减影血管造影显示左侧颈内动脉在其起始后不久缺如,且左侧上颌动脉与左侧颈内动脉鞍上段之间存在吻合。主动脉弓血管造影显示右锁骨下动脉作为左主动脉弓的第一分支发出,随后是双颈动脉干和左锁骨下动脉。颅底高分辨率CT显示左侧颈动脉管缺如,符合颈内动脉先天性缺如。
