超声引导下微波消融治疗小肝癌疗效观察

Observation on the Effect of Microwave Coagulation Therapy under Ultrasonic Guidance for Small Liver Cancer

【目的】对超声引导下微波消融治疗小肝癌的疗效进行研究。【方法】应用超声引导微波消融治疗32例小肝癌患者，共计42个癌结节，1月后应用超声造影检查。【结果】所有病倒治疗后1月超声造影，42个肿块中，其中35个肿块内血流消失，各个时相呈无回声增强。7例肿块内血流减少，未灭活部分动脉相高回声增强，门脉相及延迟相低回声增强，灭活部分各时相无增强。病人治疗后全身情况好转，症状减轻或消失，AFP和肝功能好转，未发生严重并发症。【结论】超声弓1导微波治疗对小肝癌的治疗有较好的疗效，安全实用。

[Objective]To study the curative effect of ultrasonic-guided percutaneous microwave coagulation therapy（PMCT） for the treatment of small liver cancer. [Methods]With the ultrasound guidance, 32 patients with small liver cancer（42 nodes）underwent PMCT. Contrast-enhanced ultrasonography was applied after 1 month. [Results] One month after PMCT, 42 nodes were observed with contrast- enhanced ultrasonography. The blood flow of tumors in 35 nodes disappeared. There was no enhancement in the tumors at all phases. Blood flow was decreased in 7 nodes. There was no enhancement in the inactivation part of tumors. High echo enhancement was present in activation part of tumors at arterial phase. Low-echo enhancement appeared at portal phase and delay phase. All patients were in a good condition. They showed relief or disappearance of symptoms, the improvement in AFP and liver function. And there was no severe complication. [Conclusion] Ultrasonic-guided PMCT is a safe, effective and practical method for small liver cancer.
