Abstract:
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.
