• We describe three cases of pulmonary artery slings associated with tracheal stenoses by complete cartilaginous rings and abnormalities in the tracheobronchial branching pattern. This association implicates special problems of management that are different from the simple pulmonary artery sling. Pathologic anatomy, symptoms, diagnostic procedures, and the problems of therapy are described. Considering similar cases in the literature, we conclude that thorough diagnostic evaluation of the tracheobronchial and the cardial system should be carried out in all cases of pulmonary artery sling. Simple correction of the aberrant vessel without correcting the tracheal stenosis is of no value in these cases. In some milder cases, a conservative approach is possible and probably less harmful than an operation.
