The right subclavian artery arises on its own as the fourth branch of the aortic arch, distal to the left subclavian artery, it then hooks back to reach the right-side posterior to the esophagus (aberrant right subclavian artery), no aneurysmal dilatation of its proximal portion (no diverticulum of Kommerell), no segmental stenosis in its retro-esophageal course.
Case Discussion
Aberrant right subclavian artery is among the commonest aortic arch anomalies. It is often asymptomatic (like in this case), but ~10% of people may complain of tracheoesophageal symptoms.
