Symptoms and signs

Symptoms include cyanosis, dyspnoea and apnoeic spells. Rarely it is asymptomatic and is detected incidentally in asymptomatic adults.

Cause

In pulmonary artery sling, the left pulmonary artery anomalously originates from a normally positioned right pulmonary artery. The left pulmonary artery arises anterior to the right main bronchus near its origin from the trachea, courses between the trachea and the esophagus and enters the left hilum.[1]

Treatment

It almost always requires surgical intervention. The surgery is usually open heart surgery with an incision through the sternum.[2]

History

The first known case of pulmonary artery sling was diagnosed and surgically repaired by Willis J. Potts at Lurie Children's Hospital in 1953.[2]
