Double aortic arch: An uncommon diagnosis presenting with recurrent respiratory symptoms.

Abstract

<jats:p>A vascular ring is defined as an anomaly of the great arteries (aortic arch and its branches) that&#x0D;
compresses the trachea and/or oesophagus. Double aortic arch is one of the most common types of vascular&#x0D;
rings.&#x0D;
We present a male newborn infant with double aortic arch who initially presented with inspiratory stridor&#x0D;
since birth that was aggravated by crying. He was initially worked up as a case of congenital laryngomalacia.&#x0D;
At 26 days of age, he presented to the emergency department with attacks of cough associated with stridor,&#x0D;
interrupted breastfeeding, irritability, cyanosis and apnoea. Investigations were done and the diagnosis&#x0D;
of double aortic arch was made by echocardiography and confirmed by contrast-enhanced computed&#x0D;
tomography.&#x0D;
Standard surgical division of ligamentum arteriosum was able to relieve the trachea and the symptoms</jats:p>
