A case of tracheo-bronchial stenosis after extended end-to-end aortic arch anastomosis for interrupted aortic arch treated with suspension of the ascending artery and pulmonary artery

A 9-day-old boy had pulmonary artery banding and extended end-to-end aortic arch anastomosis for ventricular septal defect (VSD) and type A interrupted aortic arch. Severe dyspnea gradually developed. At 3 months of age, intracardiac repair of VSD was performed. Weaning from the ventilator was difficult. Endoscopic examination and chest CT revealed stenosis of the right and left main bronchi and compression of tracheal bifurcation and the right and left main bronchi by the ascending aorta and pulmonary artery. Suspension of the ascending aorta and pulmonary artery was performed 15 days after VSD closure. Nine days after this procedure, the patient was weaned from respirator. Postoperative course was uneventful. Bronchial stenosis may be caused from extended end-to-end aortic arch anastomosis.
