Description

type:text

uichi Morishima, , Daisuke Satomi, We report a rare case of esophageal carcinoma accompanied by an aberrant right subclavian artery. Esophagectomy was performed on a 74-year-old man with esophageal cancer and a right retroesophageal subclavian artery was found during the operation. This brought some anatomical problems: a right recurrent nerve could not be identified when right paratracheal lymph nodes in the mediastinum were dissected. It is important for the operation to dissect recurrent nerve lymph nodes, so computed tomography (CT) must be examined in detail preoperatively because a right inferior laryngeal nerve is not recurrent if a right subclavian artery arises from the posterior wall of the aortic arch as its last branch and runs rightwards and upwards between the esophagus and the vertebra.
