Abstract
Left pulmonary artery (LPA) sling is a rare congenital anomaly in which the LPA abnormally originates from the right pulmonary artery (RPA) and courses between the trachea and esophagus to reach the left pulmonary hilum. This anomaly is frequently associated with tracheobronchial and other cardiovascular anomalies and patients may manifest with varying airway and cardiovascular symptoms. Surgical repair is often required for symptomatic patients. Clinical outcomes largely depend on the extent and severity of coexisting anomalies, particularly tracheobronchial abnormalities. We report 2 autopsy cases of LPA sling, 1 pre- and 1 post-surgical repair. Comprehensive autopsy examination was crucial for confirmation of the clinical diagnoses and identification of a rare surgical complication.
