Abstract:
Left pulmonary artery (LPA) sling is a rare congenital vascular anomaly that typically manifests in infancy with symptomatic tracheal and esophageal compression. Unrepaired patients are rarely encountered in adulthood. This case describes a 63-year-old woman with lifelong symptoms related to an unrepaired LPA sling and progressive airway obstruction. Testing confirmed severe tracheal and esophageal compression, and she underwent LPA translocation. Following surgery, her symptoms improved, with resolution of tracheal compression on imaging and normalization of pulmonary function testing.
