Radiofrequent ablation(RFA)for treating hepatocellular carcinoma(HCC)has prevailed in Japan since it was assured legally to use in *** to algorithm of treating HCC,the application of RFA was 3 nodules whose diameter are less then 3cm or single nodule within 5cm in *** instruments are devided into expansive needle type and cool-tip *** tip needle system has been more accepted in our country because of small puncture *** RFA ablation,safety margin of more than 5mm is required to bring about local control. Incidence of local recurrence after RFA for HCC≦3cm and>3cm were 6 to 21% and 8 to 40% respectively. Incidence of intrahepatic distant recurrence was 33 to 85% three years *** are also some reports decribing the complication and problems of *** presentation is focused on the complication of RFA.

目的探讨应用气管 Y 型覆膜支架治疗气道复合狭窄和食管/胸腔胃-隆突下方瘘的可行性及疗效。材料与方法根据气道复合狭窄和食管/胸腔胃-隆突瘘的特殊解剖与病变特点,设计气道一体化 Y 型覆膜内支架。X 线监视下,10例气道复合狭窄、6例食管-隆突瘘和4例胸腔胃-隆突下左主支气管瘘共置入20枚气管 Y 型覆膜支架。结果内支架一次性置入成功,10例气道复合狭窄者置入内支架后呼吸困难即刻缓解, 6例食管-隆突瘘和4例胸腔胃-隆突下左主支气管瘘完全封闭,即刻消除了呛咳症状,有效控制了肺部感染,患者生活质量明显提高。结论气管 Y 型覆膜内支架能有效解除气道复合狭窄和食管/胸腔胃-隆突瘘, 操作简单、安全、近期疗效可靠,值得进一步推广。
目的探讨气管内支架置入治疗由食管恶性肿瘤或食管金属内支架放置术后引起的气管狭窄的疗效和安全性。方法本组11例患者,男6例,女5例,年龄56~73岁,平均65.6岁。其中气管狭窄8例由食管恶性肿瘤引起,3例为食管金属内支架放置术后压迫气管造成狭窄。操作在 X 线透视下实施,在气管内共植入 11只镍钛合金支架,7只为裸支架,4只为带膜支架。支架直径1.6-1.8cm,长度4-6cm。结果所有患者均成功置入内支架(成功率100%)。术后患者气促、呼吸困难和窒息感均立即缓解或消失,血氧饱和度上升。部分患者在术后1-3天可有少量咳嗽和血痰,经对症治疗后消失,无其它并发症发生。结论采用气管内金属内支架置入的方法治疗由食管恶性肿瘤或食管金属内支架放置术后引起的气管狭窄是一种作用迅速且安全、有效的方法。
