A contrast-enhanced CT scan (CECT) of the chest done elsewhere revealed an aberrant right subclavian artery [Figure 1].

The scan showed an aberrant origin of the right subclavian artery from the medial wall of the descending thoracic aorta, just distal to the origin of the left subclavian artery [Figures 2 and 3].

The artery was next brought to the right side from behind the esophagus and the anastomosed end side to the right common carotid artery, after confirming that there was no torsion of the mobilized vessel [Figure 4].
