摘　　要：目的 :探讨B超引导下射频热凝固 (RFA)治疗肝癌的方法及疗效。方法 :B超引导下将多极射频针穿刺入瘤体 ,采用分区定点使凝固区在三维空间上完全覆盖并超出肿瘤边缘 1cm。术后检测AFP、B超或CT或肝穿细胞学检查或肝动脉造影。结果 :1月内复查 :AFP 2 0例升高者 18例降至正常 ,B超或CT检查 9例瘤体增大 ,8例无变化 ,其余缩小 ;6例肝穿者 1例瘤体边缘有活瘤细胞 ;8例肝动脉造影1例肝边缘和瘤内不同区域有散在血供。 3月复查 :2 5例瘤体明显缩小。结论 :RFA治疗只要方法得当 。To study the value of the treatment of hepatocellular carcinoma with B ultrasonographic located radiofrequency ablation(RFA).Methods: The radiofrequency multielectrodes were inserted into the hepatic carcinoma with B ultrasonographic locating.RFA was applied with the power from 50W up to 90W. RFA scope was 1cm out of the margin of the tumor mass in three dimension. After RFA treatment, the AFP level changes and the B ultrasonography, computed tomography (CT), biopsy of the liver and hepato arterioangiography were observed.Results: One month after RFA treatment ,in those with abnormal AFP level AFP falled to normal in 18/20 patients, the volume of the tumor mass were enlarged in 9 patients, not changed in 8 patients and decreased in the others at CT and/or ultrasonography. The alive cancer cells in the margin of the tumor mass were found in 1/6 patients at biopsy. The scattering bloodstream in the carcinoma was showed in 1/8 patients on hepato arteriography. After three months, the volume of the tumor was remarkably decreased in 25 patients.Conclusion: The results suggests that RFA appears to ablate hepatic carcinoma effectively as suitable method mastered.
