目的 观察纤支镜导向下国产镍钛记忆合金气管支气管支架置入的近期疗效。方法 3例气管支气管狭窄、 1例气管胃瘘并双肺感染病人 ,均为气管切开术后 ,在 ICU病房床边纤支镜导向直视下行国产镍钛记忆合金气管支气管支架置入术。结果 一次性放置成功 2例 ;1例支架位置过高 ,再次放置成功 ;1例放置位置偏低 ,经调整到位。 3例支架扩张均良好 ,呼吸困难均立即缓解 ,缺氧症状改善 ;1例气管胃瘘病人放置覆膜支架后未见胃液进入气管内 ,进食不再呛咳。结论 经纤支镜导向放置国产镍钛记忆合金支架无需 X线监视 ,可在病房床边随时操作 ;治疗气道狭窄安全有效 ;覆膜支架封闭气管胃瘘口 ,明显改善患者的生存质量
Objective To observe the short-term curative effect of domestic-made nitinol bronchus stents guided by fiberoptic bronchoscope. Methods 3 cases of tracheobronchial stenosis, 1 case of tracheo-gastric fistula and double lung infection were tracheotomy, bedside fibrolaryngoscope-guided direct vision in the ICU ward down domestic nickel-titanium memory alloy tracheal bronchial stent placement. The results of a one-time placement of 2 cases; 1 case of the stent position is too high, again placed successfully; 1 case placement is low, adjusted in place. Three cases of stent dilatation were good, immediate relief of dyspnea, hypoxia symptoms improved; 1 case of tracheal fistula patients without stent placement of gastric juice into the trachea, eating no longer cough. Conclusions The stent made of nickel-titanium memory alloy guided by fiberoptic bronchoscope can be operated at any bedside without X-ray monitoring. It is safe and effective in the treatment of airway stenosis. The stent-graft closes the tracheal gastric fistula and significantly improves the quality of life of patients
