摘要
目的 利用彩色多普勒超声检查评价肝癌集束射频消融治疗的效果。方法 采用彩色多普勒超声检测 15 2例 2 12个肝癌集束射频治疗术前 1周和术后 1个月肿瘤内部和外周血流变化。结果 治疗前 15 2例 2 12个肝癌肿块中 187个可探及血流信号 ,以动静脉混合供血为主 ;治疗后有血流的 187个肿瘤中 13 3个血流信号完全消失 ,40个血流减少 ,14个无变化 ;但有 5 1.2 %的肿瘤周边血流无变化。结论 采用彩色多普勒超声检查观察肝癌射频治疗前后血流的变化可以评价其治疗效果 。
Objective To evaluate the results of liver carcinoma treated by radiofrequency ablation(RFA) with color Doppler ultrasonography(CDU). Methods Hemodynamic changes of the interior and periphery of 212 nodules of liver carcinoma in 152 patients were investigated by CDU one week before and one month after RFA. Results Blood flow signals were found in 187 cancerous nodules before RFA, and were chiefly from mixed arterio-venous blood supply. After RFA, the blood flow signals of these 187 cancerous nodules completely disappeared in 133, were reduced in 40 and did not change in 14. Peripherar blood flow did not change in 51.2% of the tumors. Conclusions CDU is useful in evaluating the therapeutic effect of RFA in patients with liver carcinoma and may provide information for further treatment.
