目的 观察和评价镍钛记忆合金支架植入术对晚期肺癌合并气道阻塞的疗效及并发症。方法 在 X线引导下 ,经导丝及带鞘导管介入 ,用镍钛记忆合金支架植入术治疗肺癌合并支气管阻塞 15例 ,其中 13例合并一侧全肺不张 ,2例支气管重度狭窄。结果 全部支架植入成功 ,进入预定位置 ,支架膨胀满意 ,不张的肺完全复张 ,呼吸困难缓解 ,近期有效率 10 0 % ,无严重并发症。随访至 1999年 3月 ,4例死亡 ,平均带支架生存 9.2 5± 3 .4 0月 ;11例仍存活 ,平均已带支架生存 8.4 6± 5 .2 6月。结论 镍钛记忆合金支架治疗肺癌气道阻塞姑息效果好 ,植入安全 ,并发症少 ,生活质量明显提高
Objective To observe and evaluate the efficacy and complications of stent implantation for advanced lung cancer with airway obstruction. Methods Under the guidance of X-rays, catheters were inserted through the guide wire and sheathed. Nitinol-based memory alloy stent implantation was used to treat 15 cases of lung cancer with bronchial obstruction. Among them, 13 cases had one side of full atelectasis and 2 cases had severe bronchial stenosis. Results All the stents were implanted successfully, entered the pre-determined position, the stent swelled satisfactorily, the atelectic lungs completely replied, and the dyspnea was relieved. The recent effective rate was 100%, and no serious complications occurred. Follow-up to March 1999, 4 patients died, with an average survival of 9.25 ± 3.40 months with a stent; 11 patients were still alive, with an average survival of 8.46 ± 5.26 months with a stent. Conclusion Nickel-titanium memory alloy stent is effective for the treatment of lung cancer with airway obstruction, safe implantation, fewer complications, and significantly improved quality of life.
