超声引导下经皮穿刺射频消融治疗肝癌的临床价值

目的评价超声引导下射频消融（RFA）治疗肝癌的临床应用价值。方法57例肝癌患者，共83个肿瘤结节（直径1．9～6．2cm），采用LeeVeen针（3．5cm／15G十电极），术中定位、穿刺采用超声引导，≤2．0cm结节单点消融，〉2．0cm结节采用多点消融，每个肿瘤结节治疗1～3针，每3～6个月CT复查，对新出现的结节再次行RFA治疗。结果RFA术后3～7d肿瘤完全消融率93．1％（78／83），术后3、6、12、24个月CT检查，肿瘤完全坏死分别为86％、81％、72％、65％，患者存活率分别为96％、91％、84％、67％。结论超声引导下射频消融治疗肝癌具有创伤小、见效快，并可多次进行、患者痛苦小、体质恢复快，无需输血等优点，是治疗肝癌有效和安全的方法之一。

Objective To evaluate the therapeutic effects of ultrasound-guided radiofrequency ablation （ RFA ） treatment for patients with hepatocellular carcinoma by of the clinical value. Method 57 patients of the treatment of liver cancer in our hospital between January 2010 to September, a total of 83 tumor nodules （ diameterl.9to6.2cm ） , Lee Veen, needle （ 3.5 cm/15 10 electrodes ） ; surgery positioning using guided puncture. ≤ 2.0cm nodule single point ablation more than 2.0cm multi-point ablation, each tumor nodules in the treatment of a pin or 3 pin, every 3 to 6 months enhanced CT scan review, the newly discovered nodules again line RFA treatment. Result The RFA postoperative 3 to 7 days of complete tumor ablation rate was 93.1% （ 78/83 ） .3, 6, 12, 24 months in the treatment of postoperative enhanced CT scan showed that the tumor showed complete necrosis rate of 86%, respectively, 81%, 72%, 65% survival rate at 3, 6, 12, 24 months 96%, 91%, 84% and 67% . Conclusion Ultrasound-guided radiofrequency ablation is minimally invasive, quick and can be repeated after treatment, pain, and is easy to restore, no blood transfusion is need, for patients with hepatocellular carcinoma .It is an effective and safe method in the clinical treatment of liver cancer.
