A neonate with severe neonatal asphyxia was treated with therapeutic hypothermia. He developed hypothermia-induced respiratory deterioration, after which congenital tracheal stenosis and pulmonary artery sling were diagnosed. Even low-grade hypothermia is likely to induce bronchial narrowing in neonates, especially in neonates with congenital respiratory tract anomalies. Congenital tracheal stenosis represents a potential pitfall in differential diagnosis and should be carefully ruled out in cases of bronchial narrowing episode induced by therapeutic hypothermia.
