Pulmonary artery sling (anomalous origin of the LPA from the RPA)

Pulmonary artery sling is a rare defect created by anomalous origin of the left pulmonary artery from the the right pulmonary artery. The anomalous left pulmonary artery courses over the right main bronchus and then from right to left, posterior to the trachea or carina and anterior to the esophagus, to reach the hilum of the left lung. This compresses the lower trachea and right main bronchus, casusing upper airway symptoms. Compression caused by the sling can produce obstructive emphysema, atelectasis of the right and left lungs, or both. Thus, early recognition and diagnosis of pulmonary artery sling, and of stridor in a young infant, are crucial.
