Aortopexy for Tracheomalacia With Dextrocardia, Pulmonary Artery Sling, and Congenital Tracheal Stenosis

We report a rare case of coexisting pulmonary artery sling, congenital tracheal stenosis, and dextrocardia caused by right lung hypoplasia. Successful treatment of severe postoperative tracheomalacia was achieved by aortopexy, aiming displacement of the aortic arch across orthogonally in front of the trachea due to dextrocardia. The aim of this surgery was different from the usual aortopexy for tracheomalacia, which lifts the tracheal wall with the aorta. The three-dimensional evaluation considering the patient's associated malformations led to a successful result.
