INTRODUCTION: Right-sided aortic arch is a rare anomaly occuring in 0.1% of population. A complete right-sided aortic arch is an incidental finding on X- Ray while a ductus diverticulum is an out-pouching at the aorto-ductal junction. The ductus arteriosus closes and the ductus diverticulum shrinks away to a “Ductus bump”. The ligamentum arteriosum is a major source of trache-esophageal constriction, and a retro-esophageal position causes severe dysphagia. We present a case of severe dysphagia secondary to what we would like to refer as the “Unlucky Triad” of a Right sided aortic arch, a large ductus diverticulum and a retro-esophageal ligamentum.
