Intraoperative findings and gross pathology of the tracheobronchial lesion. (A) Intraoperative bronchoscopy showing the tracheal lesion with visible mucosal irregularities and narrowing, consistent with the suspected rupture. (B) Surgical field during the resection of the tracheal lesion, with white arrows indicating the location of the rupture. Careful dissection was performed to free and resect the affected area, followed by bronchial anastomosis. (C) Gross specimens of the resected tracheal segments, demonstrating severe damage and disruption of the tracheal wall, further supporting the diagnosis of tracheal rupture.
