目的探讨气管支架置入术治疗恶性气管狭窄的方法及疗效。方法17例气道狭窄的患者采用气管支架置入治疗,13例支架放置后给予化学治疗配以放射治疗。结果17例气管、主支气管狭窄的患者放置18只支架,成功率100%。支架放置后所有患者呼吸困难即刻缓解,无术中并发症。随访1~11个月,支架无再狭窄及移位,12例于随访期间死亡,平均生存期3.5个月。结论镍钛记忆合金气管支架治疗恶性气道狭窄是一种安全、有效、简单快速的方法。
Objective To investigate the method and effect of tracheal stent implantation in the treatment of malignant tracheal stenosis. Methods Twenty-seven patients with airway stenosis were treated with tracheal stenting, and 13 patients were treated with chemotherapy and radiation therapy after placement. Results Twenty-seven stents were placed in the trachea and main bronchus stenosis with a success rate of 100%. All patients with breathing difficulties immediately after stent placement ease, no intraoperative complications. During 1 to 11 months of follow-up, the stent was free of restenosis and displacement, and 12 patients died during follow-up. The mean survival time was 3.5 months. Conclusion NiTi tracheal stent is a safe, effective, simple and rapid method for the treatment of malignant airway stenosis.
