全身麻醉单向活瓣肺减容支架放置与取出技术

目的应用国产单向活瓣支架进行可弯曲支气管镜介入肺减容术（BILVR）临床研究，初步探讨支架的放置与取出技术。方法选择2006年5月至2008年3月8例重度肺气肿患者，其中男性7例，女性1例，年龄43-70岁。在全身麻醉下行可弯曲支气管镜支架置入，其中对2例患者行全部或部分取出支架。结果8例患者在单侧上叶支气管段或亚段放置4～6个支架，手术时间为（124．00±63．26）min。术后2h可自行活动，呼吸困难明显减轻。1例患者在术后2d出现非靶区下叶肺炎、1例患者出现慢性阻塞性肺疾病急性发作，均治疗后缓解。其余患者均未出现严重并发症。随访6～24个月，2例部分支架远端出现肺炎，行全身麻醉经纤维支气管镜支架取出术，未出现严重并发症。结论全身麻醉单向活瓣肺减容支架的放置与取出术操作简单．较为安全。

Study on transbronchoscopic interventional treatment with one-way valve stent in severe emphysema

Objective To evaluate the technique of implanting and withdrawing the domestic-made stents in the study on clinical application of bronchoscopic interventional lung volume reduction. Methods From May 2006 to March 2008,8 cases with severe emphyseme,male 7,female 1,aged 43 - 70 years,were implanted flexible stents under general anesthesia. Among them total or partial withdrawal were performed in 2 patients. Results Four to six stents per patient were implanted into the obstructed upper-lobe branchial segment...
