目的:采用气管内留置国产 Z 形螺旋状金属内支架,治疗肺部恶性肿瘤、隆突再造术后气管狭窄。材料和方法:2例患者均为肺癌术后隆突再造术,一例为气管软化,另一例为气管支气管内肉芽组织增生,在纤维支气管镜下置入气管内支架。结果:狭窄段气管或支气管留置支架后患者呼吸困难明显好转,脱离呼吸机,一周后出院。一例随访2.5年未见有再狭窄。结论:气管内支架是治疗气管狭窄的一种行之有效的方法。在床边非透视下亦可行气管内留置架术。
OBJECTIVE: To treat the malignant tumor of the lung and the tracheal stenosis after reconstruction by using endotracheal domestic Z-helical metal stent. MATERIALS AND METHODS: All 2 patients underwent reconstruction of lung cancer after surgery. One was tracheal softening and the other was granulation tissue of tracheobronchial hyperplasia. Tracheal stent was placed under bronchofibroscopy. Results: The patient with dyspnea improved significantly after tracheal or bronchial stent placement, and was discharged from the ventilator one week later. A case of follow-up 2.5 years did not see any restenosis. Conclusion: Endotracheal stent is an effective method for the treatment of tracheal stenosis. Under bed non-fluoroscopic tracheal indwelling stent is also feasible.
