Aberrant Right Subclavian Artery with Retroesophageal Course as a Reason of Dysphagia: A Case Report

The most prevalent vascular anomaly of the aortic arch is the aberrant right subclavian artery, which is a rare embryological aberration. It is an anatomical variation of the right subclavian artery, emerging as the last branch of aortic arch. A surgical operation involving the esophagus should take this abnormality into account. Any inadvertent damage to this artery while undergoing surgery has a high risk of death. Even though aberrant right subclavian artery can be difficult to treat during an esophagectomy, if it is identified beforehand, careful dissection of the retroesophageal area during the procedure can help avoid damaging the abnormal artery and its related consequences.
