摘要
目的评价超声引导下冷循环射频系统治疗肝癌的疗效及并发症.方法在超声引导下经皮经肝穿刺射频或术中射频治疗肝癌患者40例,共48个病灶,对比治疗前后的影像检查,评价肝癌消融是否完全,并记录射频治疗后的并发症及其转归情况.结果冷循环射频治疗后,当肝癌直径<3 cm、直径3～5 cm、直径>5 cm时,一次治疗完全坏死率分别为95.8%,73.4%及40%.三组治疗后一年时复发率分别为0,16.7%,40%.主要并发症是疼痛、发热、出血等.结论冷循环电极射频治疗肝癌,是一种适应证较广泛,疗效较为确切,副作用较少的良好方法.
Objective To evaluate the effect and complications of ultrasound-guided cool-tip radiofrequency ablation（RFA） in malignant liver trmors.Methods Forty patioents with 48 malignant liver nodules were treated with ultrasound guided percutancous transhepatic and intraoperative RFA using cool tip RFA system.The ratio of complete ablation was calculated by comparing the imaging rosults before and after RFA treatment.The complications and survival rete of the patients were also recorded.Results After one procedure treatment,the complete ablated ratio of three groups divided by the largest diameter of tumour nodules 〈3cm,3-5cm,and 〉5cm was 95.8%,73.4%,and 40% respectively.After treatments,the recurrence rate of the three groups was 0%,16.7% and 40% respectively.The main complications of RFA were pain,fever,bleeding and so on.Conclusions Cool-Tip radiofrequency ablation system is an easily performed,highly effective and safe method for the treatment of malignant liver tumours.
