[Stenting for postoperative airway stenosis due to traumatic tracheobronchial rupture].

A 43-year-old man underwent repair for the broken trachea, left main bronchus and right main brouchus due to trauma. Twenty-seven months after the initial surgery, he developed dyspnea and required ventilatory support. Computed tomography showed severe stenosis of the left main bronchus, tracheomalasia and bronchomalasia of right main bronchus. A self-expandable metallic stent (SEMS) was placed in the bilateral main bronchus and T-tube in the trachea. SEMS developed granulatory and cicatricial stenosis of the airway, which caused severe dyspnea. Replacement of SEMS with Dumon stents was successfully done and dyspnea was disappeared. A silicon stent should be used for treating postreconstructive airway stenosis including tracheobronchomalasia.
