Abstract:
A novel method for closure of the lower membranous trachea after right pneumonectomy using a flap derived from the cartilaginous portion of the right main bronchus is described in this study. This technique was used successfully in patients with tracheal stenosis due to a giant posterior mediastinal tumor known as schwannoma. Because of the severe tracheobronchial stenosis and destroyed right lung, tumor resection combined with resection of the lower membranous trachea and right pneumonectomy was carried out. We closed the defect in the membranous lower trachea with the flap derived from the right main bronchus. The clinical course was uneventful.
