Rare association of pulmonary artery sling with tracheo-oesophageal fistula and patent ductus arteriosus.

Congenital tracheo-oesophageal fistula (TEF) is a life-threatening complication caused by communication between the oesophagus and the tracheobronchial tree within the neck or the thorax. TEF without oesophageal atresia is commonly known as 'H'-type TEF, and it is extremely rare in infants, accounting for ∼2-4% of all congenital tracheo-oesophageal malformations. Here, we report a rare case of a pulmonary artery sling with TEF and patent ductus arteriosus.
