Fig 2 Contrast swallow study demonstrating severe esophageal compression in posteroanterior (A) and lateral projections (B). (A) Aortic arch had an unusual course immediately crossing the spine to the left and descending on the left side. (B) Posterior indentation of the esophagus. (C) Angiographic study demonstrating the arch vessels branching pattern. Left subclavian artery anastomosed to descending aorta by mean of a 10-mm Hemashield graft.

Fig 3 Final repair. Right aortic arch division immediately below the origin of the right subclavian artery (RSA). A 22-mm Hemashield graft was positioned from the ascending to the descending aorta.
