A 32-year-old woman was admitted to our hospital for blunt chest trauma due to a traffic accident. Bronchoscopy performed the next day revealed rupture of the trachea about 5 cm in length with airway stenosis. 6 days later, she began to complain of progressive dyspnea, and bronchoscopy showed severe stenosis of the ruptured trachea. EMS was inserted to manage the stenosis of the trachea. Dyspnea disappeared soon aftger this procedure with the tracheal lumen widely patent. 19 days after this treatment, she compained of dyspnea again and bronchoscopy showed re-stenosis of the trachea due to growth of granulation tissue within the EMS. Bronchoscopic resection of the granulation tissue was performed repeatedly but the stenosis could not be resolved by this procedure. Dumon stent was applied to control restenosis of the trachea on the 52nd day after insertion of the EMS. The clinical course has been satisfactory for one year after the use of Dumon stent and further follow up is needed to assess the long term result.
