右锁骨下动脉异常是主动脉弓的分支变异。在我们学校的例行学生解剖中,我们遇到了两具右锁骨下动脉异常的女尸体。在这两个病例中,右锁骨下动脉都不是头臂干的分支,而是直接起源于主动脉弓远端,作为最后一个分支,在食道和脊柱之间延伸至上肢。右侧喉返神经未见,但观察到一非喉返下神经从迷走神经分支直接向喉部行进。在第一种情况下,右颈总动脉和左颈总动脉分别单独起源于主动脉弓作为第一分支和第二分支,而在第二种情况下,右颈总动脉和左颈总动脉在其起源处形成颈主干。Kommerell憩室出现在第二例异常的右锁骨下动脉底部,但在第一例中没有。我们分析了两例病例的解剖学差异,并讨论了发育方面和潜在的临床风险。
An aberrant right subclavian artery is a branching variation of the aortic arch. We encountered two female cadavers with an aberrant right subclavian artery during routine student dissection at our school. In both cases, the right subclavian artery was not a branch of the brachiocephalic trunk but originated directly from the distal part of the aortic arch as the last branch and ran between the esophagus and vertebral column, traveling to the upper limb. The right recurrent laryngeal nerve was absent, but a non-recurrent inferior laryngeal nerve branching from the vagus and traveling directly toward the larynx was observed. In the first case, the right and left common carotid arteries originated solely from the aortic arch as the first and second branches, respectively, whereas the right and left common carotid arteries formed a bicarotid trunk at their origin in the second case. A Kommerell diverticulum was present at the base of the aberrant right subclavian artery in the second case, but not in the first case. We analyzed the anatomical differences between the two cases and discussed the developmental aspects and potential clinical risks.
