保存的治療により治癒にいたった外傷性気管損傷が疑われた1例

Tracheal Injury Successfully Treated without Surgery；Report of a Case

交通外傷による気管・気管支損傷の発生頻度はまれであるが，死亡率は高く致命的となりうる．われわれは，外傷性気管損傷が疑われたが保存的治療により治癒にいたった気管軟化症を合併した1例を経験したので報告する．

A 73-year-old man was injured after crashing his automobile into a concrete wall, and was admitted to our hospital with breathing difficulties. Chest computed tomography showed extensive mediastinal emphysema, right traumatic pneumothorax, and a suspected tracheal injury at the membranous region. Because of the associated tracheomalacia, the site of the tracheal injury was difficult to find by bronchoscopy. In addition, as the patient’s respiratory condition was stable, surgical treatment was not chosen. Due to the continuous air leakage from the right lung, the patient underwent surgery after mediastinal and subcutaneous emphysema improved. The postoperative course was uneventful.
