US-guided puncture is the simplest and most popular method in the RFA treatment for HCC. However, depending on the location of tumors, it is often difficult to detect them by US. We report here the utility of CT-guided RFA for the treatment of HCC. We performed CT-guided RFA for 27 nodules in 21 patients with HCC from July 1999 to June, 2001. We used the LeVeen Needle Electrode made by Boston Company and the Cool-tip type electrode made by Radionics Company. We judged the effects of the treatment by dynamic CT within 7 days after RFA. We were able to accomplish the treatment for all patients with the exception of one case who developed severe pain during RFA. We experienced transient increases of AST/ALT in a few cases, subcutaneous emphysema in one case, pleural effusion and ascites in two cases, but conservative treatments were effective for all cases. US-guided puncture was especially useful for the treatment of the tumors localized below the diaphragm that were hardly detectable by US.
超声引导下穿刺是肝癌射频消融治疗中最简单且最常用的方法。然而，根据肿瘤的位置，通过超声检测它们往往很困难。我们在此报告CT引导下射频消融治疗肝癌的效用。1999年7月至2001年6月，我们对21例肝癌患者的27个结节进行了CT引导下射频消融治疗。我们使用了波士顿公司生产的LeVeen针电极和Radionics公司生产的冷极型电极。我们在射频消融术后7天内通过动态CT判断治疗效果。除1例在射频消融术中出现严重疼痛的患者外，我们成功完成了所有患者的治疗。我们有几例患者出现了AST/ALT短暂升高，1例出现皮下气肿，2例出现胸腔积液和腹水，但所有病例的保守治疗均有效。超声引导下穿刺对于治疗位于膈肌以下难以通过超声检测到的肿瘤特别有用。
