Pulmonary artery sling and tracheal bronchus presenting in a 2-year-old child.

Pulmonary artery sling is an incomplete vascular ring, the result of the left pulmonary artery arising from the right pulmonary artery and effectively constricting the airway, and it usually presents within the first weeks to months of life. We report a surgical correction of tracheal stenosis for a two-year-old patient associated with pulmonary artery sling and tracheal broncus.
