Surgical repair of pulmonary artery sling in an adult.

Pulmonary artery sling is a rare congenital vascular anomaly that typically presents in the first month of life with severe respiratory symptoms. In this condition, the left pulmonary artery originates off the right pulmonary artery and courses between the trachea and esophagus, causing compression of both structures. Of those patients with pulmonary artery sling, a small subset survives to adulthood with few or no symptoms. In this article we present the surgical correction of pulmonary artery sling in an adult patient.
