A 17-days-old-girl with pulmonary artery(PA)sling, patent ductus arteriosus(PDA), and persistent left superior vena cava was admitted to our hospital. Despite good respiratory status just after birth, the respiratory status gradually worsened, and tracheal intubation was performed on 13th day after birth. Emergency division of the PDA was conducted on day 16. Although preoperative computed-tomography did not demonstrate tracheal stenosis, bronchoscopy after tracheal intubation revealed progression of tracheal stenosis with difficulty for stable anesthetic management. Therefore, operation was postponed to re-evaluate tracheal stenosis. Bronchoscopy and computed-tomography revealed the worsening of tracheal stenosis. Eventually, we performed total correction of the PA sling and tracheal stenosis on day 17. Cardiopulmonary bypass was established after median sternotomy. After transection of the PDA, the left PA originating from the right PA was also transected, and transplanted to the main PA. Then, sliding tracheoplasty was performed following the division of the tracheal stenotic region. Her respiratory condition improved after operation, and postoperative computed-tomography showed successful correction of tracheal stenosis. Although few such cases were reported for neonatal PA sling requiring concomitant tracheoplasty, this case suggests that total correction of PA sling and tracheal stenosis is feasible and useful surgical procedure for such cases.
