目的研究经纤支镜放置气管支架治疗气管狭窄的临床效果。方法在X线监视下,经纤支镜置入镍钛记忆合金支架治疗15例恶性肿瘤引起的严重气管狭窄。结果15例患者术后狭窄段气管得到充分扩张,呼吸困难立即缓解。结论放置气管支架是治疗晚期恶性肿瘤引起严重气管狭窄的有效方法,值得临床推广。 Objective To study the clinical effect of tracheal stent placed by bronchoscope on tracheal stenosis. Methods Under X - ray monitoring, 15 cases of severe tracheal stenosis caused by malignant tumor were treated by stent placement of nitinol stent. Results In 15 patients, the trachea of ​​the stenotic segment was fully expanded and the dyspnea was relieved immediately. Conclusion Tracheal stent placement is an effective method for the treatment of advanced malignant tumors causing severe tracheal stenosis and is worthy of clinical promotion.
