目的 探讨记忆镍钛合金支架治疗气管支气管狭窄的疗效。方法 在X线监视下 ,经纤维支气管镜放置合金支架治疗气管支气管狭窄患者 42例 ,并观察放置合金支架前、后患者血氧饱和度的变化。结果 本组 42例患者经放置合金支架后 ,显效 3 2例 ,患者狭窄管腔直径显著增加 ,通气功能明显改善 ,血氧饱和度较术前显著提高 (P <0 .0 0 1) ,生活质量明显改善。结论 记忆镍钛合金支架是治疗气管支气管狭窄的一种有效、安全和可靠的方法。
Objective To investigate the curative effect of memory nickel-titanium stent on tracheobronchial stenosis. Methods 42 cases of tracheobronchial stenosis were treated with bronchoscope under the X-ray monitoring. The changes of oxygen saturation before and after the stent placement were observed. Results 42 cases of this group were treated with alloy stent, markedly effective in 32 cases, the patient stenosis lumen diameter increased significantly improved ventilation function, oxygen saturation significantly increased compared with preoperative (P <0. 001), life Quality improved significantly. Conclusion Memory Nitinol stent is an effective, safe and reliable method for the treatment of tracheobronchial stenosis.
