Many anomalies of the aortic arch and great vessels are uncovered as serendipitous findings on imaging studies, in the anatomy laboratory, or at surgery. A 56-year-old man had an arch angiogram as part of an evaluation for cerebrovascular disease. A four-vessel left aortic arch was identified consisting of the right carotid, left carotid, right subclavian, and left subclavian arteries. The right common carotid gave rise to the right vertebral artery in the chest while the normally located left vertebral arose from the left subclavian artery. No aneurysm or aortic diverticulum was identified.
许多主动脉弓和大血管异常是在影像学检查、解剖实验室或手术中偶然发现的。一名56岁男性因脑血管疾病评估接受了主动脉弓血管造影。发现一个四血管左主动脉弓，由右颈总动脉、左颈总动脉、右锁骨下动脉和左锁骨下动脉组成。右颈总动脉在胸部发出右椎动脉，而正常位置的左椎动脉发自左锁骨下动脉。未发现动脉瘤或主动脉憩室。
