彩色多普勒血流检查在肝癌介入性栓塞化疗中的价值

CDFI evaluation of liver cancer treated with transcatheter arterial embolization

目的 采用彩色多普勒显像技术评价肝癌介入性栓塞化疗的近期效果。方法 采用彩色多普勒血流显像仪观察 2 2例肝癌患者介入性栓塞化疗前后肿瘤内血流动力学的变化 ,并与肿瘤大小相联系比较。结果 介入性栓塞化疗可使原发性肝癌的血流明显减少 ,其多血供肿瘤由治疗前的 60 %降至治疗后的 13 % ,而无血供肿瘤由治疗前的 13 %增加到治疗后的 3 3 %。近期观察显示 ,血流减少或消失与肝癌肿块缩小相一致。结论 彩色多普勒血流检查对肝癌介入性栓塞化疗具有预后判断的作用和指导重复治疗的意义。

Objective Using CDFI to evaluate the therapeutic effect of transcatheter arterial embolization(TAE) on human hepatic cancer Methods Hemodynamic changes of 22 patients with liver cancer and their relationship to tumor size were investigated by CDFI before and after treatment with TAE Results In primary hepatocellular carcinoma, there was a marked reduction in blood signals in the tumor after treatment with TAE Number of tumors with rich blood supply was decreased from 60% to 13% while the tumors lack of blood supply was increased from 13% to 33% after the treatment And the reduction in blood supply in tumor was consistent with the decrease in tumor size in these patients with a short term following up. Conclusion CDFI appeared to be a useful method of evaluating prognosis and guiding further therapy for liver cancer patients having TAE
