In the cadaver of a Japanese 79 year-old man a retroesophageal right subclavian artery was observed to be derived from the arch of the aorta slightly distal and dorsal to the left subclavian artery. Its origin formed Kommerell's arterial diverticulum (50 mm in circumference), and it passed between the esophagus and the vertebral column and continued to the right to become the axillary artery. No right recurrent laryngeal nerve was observed. There was a right ansa subclavia around the subclavian artery. Although this anomaly is relatively rare, it is important as a cause of dysphagia lusoria.
在一名79岁日本男性尸体上，观察到一条食管后右锁骨下动脉发自主动脉弓，位置略低于左锁骨下动脉且在其后方。其起始处形成了Kommerell动脉憩室（周长50毫米），该动脉在食管与脊柱之间穿过，向右延续成为腋动脉。未观察到右喉返神经。在锁骨下动脉周围有右锁骨下襻。尽管这种异常相对罕见，但作为引起迷走性咽下困难的原因，它很重要。
