Pulmonary artery sling is an uncommon vascular anomaly and can be life thre
atening when it causes tracheal compression. We report on a 14-day-old boy
who presented with respiratory distress soon after birth. A series of exami
nations showed tracheal stenosis due to a pulmonary artery sling. Surgery w
as performed with the aid of cardiopulmonary bypass. The external compressi
on and intrisic stenosis could not be resolved by vascular surgery because
of tracheal malacia and a complete tracheal ring. We recommend cutting extr
a holes 1 to 2 cm from the distal end of the endotracheal tube for endobron
chial intubation. The airway obstruction was resolved successfully with a c
ustom-made endobronchial tube. However, the patient died of pneumomediastin
um and pneumothorax induced by barotrauma, on the fourth postoperative day.
