(A) Anterior view of the mediastinum and neck unveiled the retroesophageal right subclavian artery (a), right common carotid artery (b), left common carotid artery (c), left subclavian artery (d) and the right non-recurrent inferior laryngeal nerve (red arrow) of the vagus nerve (CN X). Arteries (b) to (d) directly originated from the aortic arch (e). No brachiocephalic trunk was observed. (B) Posterior view of the same specimen showing the retroesophageal right subclavian artery (a) arising from the proximal thoracic aorta (f) and coursing obliquely behind the esophagus (g). (C) Right posterolateral view of the same specimen illustrating notable esophageal impression (red arrowheads) caused by the retroesophageal right subclavian artery (a), which was reflected to the left
