A 36-year-old woman, who had surgery in 1998 for tracheal compression from a right-sided aortic arch, presented with chest pain. Multidetector computed tomography illustrated the post-operative findings and excluded acute pathology. A sling, wrapped beneath the ascending arch and around the second rib, provides anterior traction on the aorta to relieve tracheal obstruction (A to C). The ligamentum arteriosum and Kommerell diverticulum, which had been compressing the esophagus, have been divided and oversewn. The aberrant left subclavian artery (Lt.SA), formerly originating from the Kommerell diverticulum, is anastomosed to the left common carotid artery (Lt.CCA). From proximal to distal, the branches arising from the right-sided aortic arch are the Lt.CCA, right common carotid artery (Rt.CCA), and right subclavian artery (Rt.SA). Only few instances of this surgery have been described, which was performed by the late Dr. Hermes Grillo (case 4, reference 2) (1).
Dedicated to the memory of H. C. Grillo, who pioneered surgery of the trachea and bronchi.
