超声引导下射频消融治疗原发性肝癌的临床研究

目的观察超声引导下射频消融治疗原发性肝癌的疗效。方法在B超引导下,将射频电极针经皮穿刺入肝肿瘤内,对其进行原位毁损消融。结果 46例患者共55个病灶,直径<3.5 cm的23个瘤体,20个完全消融毁损,消融毁损率为86.96%;直径为3.5～8 cm的15个瘤体中11个瘤体获得完全消融毁损,消融毁损率为73.33%,直径>8 cm的17个瘤体中(其中8例直径>10 cm)12个瘤体获得完全消融毁损,消融毁损率为70.59%。结论经皮肝穿刺射频消融术对于原发性肝癌疗效可靠,是一种安全、有效的治疗方法。

Clinical study on f ultrasound guided radiofrequency ablation in the treatment of primary hepatic carcinoma

Objective To observe the therapeutic effect of ultrasound guided radiofrequency ablation in the treatment of primary hepatic carcinoma.Methods Under the guidance of B-ultrasonography,radiofrequency electrode needle were punctured into liver tumor percutaneously,and the tumor was impaired in situ.Results Of 55 lesions in 46 patients,23 were of a diameter of less 3.5,among which,20 were totally impaired,with an ablation rate of 86.96%;15 were of a diameter of 3.5-8 cm,among which,11 were totally impaired,with an ablation rate of 733.33%;and 17 were of a diameter of more than 8cm(8 tumors had a diameter of more than 10cm),among which,12 were completely impaired,with an ablation rate of 70.59%.cm.Conelusion Percutaneous radiofrequency ablation is a safe and effective meathod in the treatment of primary liver cancer.
