摘要
目的:评价超声引导下重叠布针内冷循环射频消融肝癌的临床应用价值。方法:71例患者,115个肿瘤结节(直径2.2～9cm),在超声引导下应用18G针尖裸露长度为2～3cm的冷循环电极针进行RFA治疗。每个肿瘤结节治疗2～8次,采用立体布针,多点重叠法。新发现的结节再次行RFA治疗。结果:即有患者临床症状改善,未发生严重伴发症,CT显示肿瘤完全坏死率在术后3～7天、3、6、12、24个月分别为88%、81%、78%、63%、40%,存活率在3、6、12、24个月分别为98%、95%、88%、61%。结论:超声引导下重叠布针内冷循环消融肝癌是有效和安全的方法,减少了残余肿瘤的机会,扩大了适用范围,延长了患者的寿命,改善了患者生活质量。
Objective:To evaluate the clinical value of radiofrequency ablation using cooled-tip electrode in the treatment of hepatic cancer by overlapping needle placement.Methods:Seventy-one patients with 115 hepatic cancer nodules(2.2～9 cm diameter) were treated with RF ablation using cooled-tip,18-gauge electrodes with 2～3 cm tip exposure under ultrasound-guidence.Each nodule was treated in two or eight treatment sessions by overlapping needle placement.Contrast-enhanced CT follow-up was performed every 3～6 months.new nodules were retreated with RF.Results:The sympton of all patients were improved,and three was no complications.CT comfirmed that complete necrosis rate of the entire tumor nodules was 88%,81%,78%,63%,40%,at 7 days,3,6,12,24 months.Overall survival rate was 98%,95%,88%,61% at 3,6,12,24 monthis respectively.Conclusion:Ultrasound-guided percataneous radiofrequency ablation of hepatia cancer with cooled-tip electrodes is effective and safe.
