Abstract


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