Clinical Differential Diagnosis:
Vascular ring due to a double aortic arch or a left aortic arch with an aberrant right subclavian artery

Imaging Differential Diagnosis:
Left aortic arch with aberrant right subclavian artery, double aortic arch.

Operative Findings:
Esophagoscopy and laryngoscopy was performed one day after the Upper GI and demonstrated compression of the anterior wall of the trachea by a pulsating vessel, felt to be innominate artery. Compression of the posterior wall of the mid-esophagus was also seen and felt to be caused by a pulsating blood vessel. The vascular ring was electively divided 6 days later via a left posterolateral thoracotomy. The posterior aortic arch was divided, causing an impressive release of the ring with the 2 ends of the posterior arch separating by 2 to 3 centimeters. The ligamentum arteriosum was then divided.
