Treatment of thoracostomach-airway fistula with airway covered stent

目的 :探讨覆膜内支架置入气道治疗胸腔胃 -气道瘘的可行性与疗效。方法 :根据胸腔胃 -气道瘘口的位置、大小、数目选择内支架。透视下 ,6例患者 8处瘘在气道内置入 8枚气道覆膜内支架封堵瘘口。结果 :6例内支架均置入成功 ,瘘口完全封闭 ,即刻消除呛咳症状。 5例有效控制肺部感染 ,患者生活质量得以提高 ;1例支架置入 5d后支架移位导致呼吸衰竭而死亡。随访 4～ 1 5个月 ,3例死于机体衰竭 ,1例死于呼吸衰竭 ,1例正常生活至今。结论 :气道覆膜内支架能有效封堵胸腔胃 -气道瘘 ,操作简单、安全、近期疗效可靠。

Aim: To study the effects of treating thoracostomach-airway fistula with airway covered stent. Methods:Covered stents was selected based on the site, size and number of thoracostomach-airway fistula. Under the fluoroscopic guidance, 8 covered stents were placed to close 8 fistulas in 6 patients. Results:All stents were implanted successfully. Choke after drinking and eating vanished as soon as the fistulas were closed. The pneumonia infection was effectively controlled in 5 patients. One patient died from stent movement. After 4～15 months' follow-up, 4 patients died and one was alive. Conclusion:Covered stent can be used to close the thoracostomach-airway fistula. The technique is easy, safe and effective.
