Chest radiograph, angiogram, intraoperative, and pathologic images from a neonate with pulmonary artery sling and tracheal stenosis
(A) A chest radiograph shows a hyperexpanded right lung with flattening of the hemidiaphragm (arrowhead) and leftward shift of the cardiomediastinal silhouette (arrow). (B) A pulmonary angiogram shows aberrant origin of the LPA (arrowhead) from the RPA (arrow). (C) Intraoperative photograph demonstrates the LPA (arrow) coursing behind the trachea (*). (D) Pathologic specimen shows the trachea has a focal narrowing above the bifurcation (arrow), likely due to complete tracheal rings at that location.
LPA: left pulmonary artery; RPA: right pulmonary artery.
