摘　　要：目的探讨放疗定位固定装置在肝癌射频消融术中的应用价值。方法 80例模拟定位CT引导下行肝癌射频消融术的患者随机均分为两组:A组采用可移动激光定位配合真空气垫固定,B组采用常规CT引导。比较两组首次穿刺成功率及操作时间。结果 A组首次穿刺成功率高于B组(92.5%vs.72.5%),操作时间短于B组[(7.5±2.0)min vs.(9.6±3.1)min](P<0.05)。结论使用放疗定位固定装置行肝癌射频消融术的首次穿刺成功率较常规CT引导下高,且手术时间短。Objective To explore the clinical value of laser positioning and fixed device in CTguided radiofrequency ablation of hepatic carcinoma.Methods Eighty patients with hepatic carcinoma received CT-guided radiofrequency ablation were equally randomized into two groups.Group A received laser positioning and vacuum bag fixation and group B received conventional CT-guided radiofrequency ablation.The success rate of the first puncture attempt and operation time were compared between two groups.Results The success rate of the first puncture attempt was higher and operation time was shorter in group A than those in group B [（92.5% vs.72.5%）and（7.5±2.0）minutes vs.（9.6±3.1）minutes]（P〈0.05）.Conclusion Compared to conventional CT-guided radiofrequency ablation of hepatic carcinoma,the use of laser positioning and vacuum bag fixation device for CT-guided radiofrequency ablation of hepatic carcinoma has a higher success rate of the first puncture attempt and shorter operation time.
