摘要
目的:探讨射频消融(Radiofrequency ablation,RFA)治疗肝脏肿瘤的疗效和安全性。材料与方法:CT导向下经皮穿刺冷循环射频消融治疗肝脏恶性肿瘤38例,共55个病灶,其中原发性肝癌28例,转移性癌10例,治疗后用增强CT和MRI评价消融效果,并观察并发症和生存率。结果:RFA治疗后4周复查,肿瘤直径≤3cm,直径3cm～5cm,直径≥5cm,完全坏死率分别为91%,70%和17%,一年生存率为94%,无严重并发症。。结论:CT导向下经皮穿刺射频消融治疗肝脏肿瘤是一种安全、有效的方法。
Purpose： To evaluate the therapeutic efficacy and safety of radiofrequency ablation in treatment of malignant hepatic tumors under CT- guided. Materials and Methods： 38 patients with 55 malignant tumors were treated by using Cool - tipradiofrequency ablation under CT-guided, of those, 28 cases were primary liver cancers and 10 hepatic metastases. After treatment, Contrast enhanced CT or MPI scans were performed in order to assess the effect of lesions. Complications and the survival rates were also investigated. Results： 4 weeks after treatment, Complete ablation rates of the tumors＇ s diameter ≤〈3cm, 3cm- 5cm and ≥5cm were 91%, 70% and 71% respectively, one year survival rates were 94%, without severity complicatious. Conclusion： CT - guided radiofrequency ablation in the treatment of liver tumors is an effective and safe method.
