In early embryogenesis, aortic anomalies occur as a consequence of disorders in the development of the primitive aortic arches system. Aberrant right subclavian artery, also known as arteria lusoria, is one of the important congenital anomalies of the aortic arch, in which the right subclavian artery arises from the arch of aorta instead of the brachiocephalic trunk. During routine dissection of a female cadaver, we observed retro-oesophageal aberrant right subclavian artery arising as the fourth branch from the aortic arch. In this case, the brachiocephalic trunk was absent. Early detection of aortic arch anomalies through diagnostic interventions is helpful to avoid complications during surgical procedures.
在胚胎早期，主动脉异常是由于原始主动脉弓系统发育障碍引起的。右位锁骨下动脉异常，也称为迷走右锁骨下动脉，是主动脉弓重要的先天性异常之一，其中右锁骨下动脉起源于主动脉弓而不是头臂干。在对一名女性尸体进行常规解剖时，我们观察到食管后右位锁骨下动脉从主动脉弓第四分支发出。在这种情况下，头臂干缺失。通过诊断干预早期发现主动脉弓异常有助于避免手术过程中的并发症。
