Double aortic arch in Honduras: an unusual cause of dysphagia in an adult patient. A case report.

Vascular rings represent less than 1% of congenital cardiovascular anomalies, with double aortic arch being the most common variant. It is typically diagnosed in infants, with respiratory symptoms in over 90% of cases. We present the case of a 31-year-old male patient with recurrent childhood respiratory infections and asthma, who presented with progressive dysphagia. Contrast-enhanced computed tomography angiography revealed a double aortic arch with right-sided dominance, and the esophagram revealed compression of the proximal third of the esophagus. A left posterolateral thoracotomy was performed with division of the distal left arch, division of the ligamentum arteriosum, adhesions release, and thoracic aorta reconstruction. Postoperative recovery was favorable, with complete resolution of symptoms. Double aortic arch is rarely diagnosed in adulthood. This case highlights its atypical presentation, with predominant gastrointestinal symptoms, and the importance of considering it in the differential diagnosis of dysphagia.
