Abstract:
Pulmonary artery sling is an incomplete vascular ring, where the left pulmonary artery originates from the right pulmonary artery, leading to airway constriction. A tracheal bronchus is an anatomical variation in which an extra bronchus originates from the trachea, frequently resulting in respiratory symptoms or complications. We report a 6-week-old female patient with a pulmonary artery sling coursing around the distal trachea and a concurrent tracheal bronchus.
