【摘要】：目的探讨应用CEUS评估多电极冷循环射频消融(RFA)治疗小肝癌后肿瘤灭活程度的价值。方法对49例小肝癌患者(63处病灶)RFA治疗前后分别进行常规超声、CEUS检查及增强CT检查,评估病灶完全消融及局部残留情况。结果 RFA治疗前,CEUS测量病灶最大径为(2.47±0.53)cm,常规超声测值为(2.12±0.57)cm,二者差异有统计学意义(t=-4.907,P0.05)。CEUS测量病灶面积为(6.50±1.26)cm2,常规超声测值为(5.43±1.06)cm2,差异有统计学意义(t=-6.867,P0.05)。CEUS与增强CT对病灶检出率差异无统计学意义(χ2=0.25,P0.05)。RFA治疗后,CEUS判断肿瘤完全灭活与局部残留情况与增强CT差异无统计学意义(χ2=0.50,P0.05)。结论 CEUS可用于评估小肝癌RFA治疗效果。
[Abstract]:Objective to evaluate the value of CEUS in the evaluation of tumor inactivation after multi-electrode cold circulation radiofrequency catheter ablation (RFA) for small hepatocellular carcinoma (HCC). Methods 49 patients with small liver cancer (63 lesions) were examined by conventional ultrasound CEUs and enhanced CT before and after RFA treatment to evaluate the complete ablation and local residual of the lesions. Results before RFA treatment, the maximum diameter of lesions measured by CEUs was (2.47 卤0.53) cm and that by conventional ultrasound was (2.12 卤0.57) cm. There was a significant difference between CEUS and enhanced CT in detecting lesion area (6.50 卤1.26) cm ~ (2) and conventional ultrasound (5.43 卤1.06) cm ~ (2), respectively. There was no significant difference in the rate of tumor inactivation and local residual after RFA treatment (蠂 2 / 0.25 P 0.05). There was no significant difference between CEUs and enhanced CT (蠂 2 / 0.50 P 0.05). Conclusion CEUS can be used to evaluate the efficacy of RFA in the treatment of small hepatocellular carcinoma.
