危重恶性气管狭窄的气管支架治疗

目的：探讨气管支架抢救治疗危重恶性气管狭窄患者的方法和应用价值。方法：对8例恶性肿瘤所致重度气管狭窄的危重患者，置入气管支架治疗。使用Gianturco Z形支架5个，网状支架2个，Ultraflex支架1个。结果：全部患者均1次置入成功，呼吸困难立刻得到缓解。随访，1例患者术后3个月，现生存仍在观察中。7例死亡，生存时间52－213天，平均112天。结论：气管支架能快速、有效地开通气道，是抢救治疗恶性肿瘤所致危重气管狭窄的有效方法。熟练，合理地操作是支架置入成功的安全保障。

Tracheal Stent for Treatment of Malignant Severe Airway Obstruction

Objective: To study the applied value of tracheal stent for treatment of malignant severe airway obstruction. Methods :Gianturco Z stents(n= 5), net stents (n = 2) and Ultraflex stent(n = 1) were used to treat 8 patients with severe tracheal stenosis caused by malignant tumor. Results: All of the patients were treated successfully by one time, and their respiratory distresses were relieved immediately after treatment. The survival time of these patient was 52~213(mean: 112) days. Conclusion: The tracheal stent can rapidly and effectively open a narrowed airway. It is an effective method to treat the severe tracheal stenosis caused by malignant tumor. A skilled and reasonable operative method is the safe guarantee for successful stent implantation.
