# Vascular ring due to double aortic arch as a cause of stridor and dysphagia in infancy: a case report

## TL;DR

A rare case of a double aortic arch causing breathing and swallowing issues in a young boy was successfully treated with surgery.

## Contribution

This case report adds to the understanding of vascular ring management in infants with persistent symptoms.

## Key findings

- Surgical correction of the non-dominant aortic arch resolved tracheoesophageal compression.
- Symptoms and nutritional status improved completely after 12 months of follow-up.
- Timely intervention is crucial for reversing symptoms and improving quality of life.

## Abstract

A double aortic arch is a rare congenital vascular anomaly with clinical significance in the pediatric population due to its potential to cause extrinsic compression of the trachea and esophagus. It should be suspected in infants with persistent respiratory and gastrointestinal symptoms refractory to conventional treatment. We report the case of a 2-year-7-month-old boy presenting with recurrent stridor, repeated respiratory infections, and progressive dysphagia. Cardiac CT angiography revealed a complete vascular ring causing tracheoesophageal compression. Dominance of the left aortic arch was identified, and surgical section and distal ligation of the non-dominant right arch were performed, without direct intervention on the tracheoesophageal structures. At the 12-month follow-up, there was complete resolution of symptoms and nutritional recovery. This case highlights the importance of maintaining high clinical suspicion and ensuring timely referral. Even when surgical correction is delayed, appropriate intervention can reverse symptoms and improve quality of life
