An aortic arch variant was found in a 63 year-old male cadaver during routine dissection. An aberrant right subclavian artery (ARSA) arose from the distal aortic arch after the left subclavian artery and coursed to the right and upward behind the trachea and esophagus. A common origin for the carotid arteries (COCA) accompanied this variant of the right subclavian artery.
在对一名63岁男性尸体进行常规解剖时发现了一种主动脉弓变异。一条迷走右锁骨下动脉（ARSA）起自左锁骨下动脉后方的主动脉弓远端，向右上行，走行于气管和食管后方。这种右锁骨下动脉变异伴有颈动脉共同起源（COCA）。
