Primary repair of pulmonary artery sling with double outlet right ventricle and distal tracheal stenosis.

The fate of patients with pulmonary artery sling depends on associated tracheal lesions. Distal tracheal stenosis involving the carina frequently results in lethal obstruction due to secretion or inflammatory edema. Further-more, associated complex cardiac anomalies with excessive pulmonary flow make the situation more complicated. We present a case of successful simultaneous one-stage repair of pulmonary artery sling, double outlet right ventricle and distal tracheal obstruction. Pulmonary artery sling was relieved by relocation of the left pulmonary artery (left pulmonary artery to main pulmonary artery) and a tracheoplasty (resection and end-to-end anastomosis). We advocate early aggressive simultaneous repair of pulmonary artery sling with tracheal stenosis and concomitant repair of intracardiac anomalies whenever possible.
