Blunt tracheal injury is a rare but life-threatening condition. Several indications for treatment have been reported. Conservative treatment (i.e., stenting) can be performed when the patient is clinically stable or has medical contraindications to surgical treatment. Although some studies have reported the use of tracheal stents as treatment for iatrogenic injury and blunt trauma, the efficacy of these stents is unknown. Herein, we report a case of emergency tracheoplasty for the management of tracheal stent prolapse in a patient with blunt tracheobronchial trauma. This report highlights the necessity of being cautious about the migration and prolapse of tracheal stents, which can more frequently occur in blunt trauma than in malignant stenosis or iatrogenic injury. Due to the limitations of non-surgical treatments, early surgical intervention may be lifesaving.

钝性气管损伤是一种罕见但危及生命的疾病。已经报道了几种治疗适应症。当患者临床情况稳定或有手术治疗的医学禁忌症时，可以进行保守治疗（即支架置入术）。虽然一些研究报道了使用气管支架治疗医源性损伤和钝器外伤，但这些支架的疗效尚不清楚。在此，我们报告了一例急诊气管成形术，用于治疗气管支气管钝挫伤患者的气管支架脱垂。本报告强调了对气管支架的移位和脱垂保持谨慎的必要性，这在钝性创伤中比在恶性狭窄或医源性损伤中更常见。由于非手术治疗的局限性，
