Pulmonary artery sling (PAS) is a rare congenital condition, in which the left pulmonary artery (LPA) originates from the right pulmonary artery instead of the main pulmonary artery. It courses between the oesophagus and the trachea, forming a sling and causes compression of both structures. We report a very rare case of a symptomatic adult patient with PAS and a coexisting tracheal anomaly with complete tracheal rings, referred to as a ‘ring-sling complex’.
