纤维支气管镜引导下置入内支架治疗气道狭窄的临床研究

Clinical study of stents guided by fiberbronchoscope for tracheobronchial stenosis

目的对气道狭窄患者于纤维支气管镜引导下行气道内支架成形术的临床应用进行评估。方法纤维支气管镜引导下对36例气道狭窄合并严重气促患者行气道内支架成形术,观察治疗前后患者气道直径、气促症状的改善情况。结果36例均获成功,支架留置后患者气促立即改善,气道直径由(5.36±1.76)mm扩大为(11.66±2.48)mm(P<0.01)。结论纤维支气管镜引导下内支架成形术能显著提高气道狭窄患者的生活质量,气管支架置入术是治疗重症气道狭窄的有效方法,可在有条件的单位广泛开展。

Objective To make an estimate of clinical practical of stents guided by fiberbronchoscope for tracheo-bronchial stenosis. Methods Stents were put in the tracheobronchial guided by fiberbronchoscope for 36 patients with tracheobronchial stenosis and asthma, airway diameters and dyspnea index were respectively evaluated before and after treat-ment. Results All 36 cases were successful and the problem of asthma was solved, airway diameter increased from （5.36±1.76） ram to （11.66±2.48） mm （P〈0.05 ）. Conclusion The living quality of the tracheobronchial stenosis patient is improved by stents,The tracheal stent implantation is an effective method for severe tracheal stenosis. And this operation may be widely promoted in higher hospitals.
