摘　　要：目的总结气管支架置入术治疗重症气道狭窄的疗效和经验。方法各种原因引起的气管和主支气管狭窄患者13例。术前常规行高千伏胸部X线摄片和CT检查以了解气道狭窄的部位、形态和范围。狭窄段位于气管10例、右侧主支气管1例、左主支气管2例。在透视下将多功能导管配合超滑导丝经过声门进入气管,随后更换金属加强导丝并随导管越过狭窄段,将导丝留置于狭窄段远端,撤除导管,将装有支架的置入器沿导丝送至狭窄段,释放支架。结果全部支架均成功置入,技术成功率100%。术后所有患者呼吸困难症状明显改善,恶性肿瘤患者平均存活时间为6.2个月,1例良性气管狭窄患者随访5年仍无再狭窄。结论气管支架置入术是治疗重症气道狭窄的有效方法。Objective To evaluate the therapeutic effects and experience of the tracheal stent implantation for the management of severe tracheal stenosis. Materials Thirteen patients with severe tracheal stenosis of various causes underwent high kilovoltage radiography and computed tomography for evaluating the site, form and extent of the stenosis including 10 at the trachea, 1 at the right main bronchus and 2 at left main bronchus. The C2 catheter assisted with ultra-slipping guide wire was inserted into the trachea under fluoroscopy and then a replaced high shoring guide wire was pushed through the stenotic segment and retained the stent. Results All stents were implanted successfully with successful rate 100% together with dyspneic improvements. The mean survival time was 6.2 months for patients with malignant neoplasm. One patient with benign tracheal stenosis has been followed-up for 5 years without restenosis, Conclusions The tracheal stcnt implantation is an effective means for severe tracheal stenosis.
