Abstract

The retroesophageal right subclavian artery is an anatomical abnormality encountered by anatomists and pathologists and recently interventional cardiologists and thoracic surgeons have also come across this phenomenon. We report a case of a retroesophageal right subclavian artery arising from a normally located left aortic arch in a young male autopsied in the Department of Forensic Service of Warsaw Medical University. In addition to the aforementioned anomaly, the presence of a right non-recurrent inferior laryngeal nerve was noticed. The possible embryonic development of these branching patterns and their clinical significance is discussed.
