目的 利用超声显像引导肝癌射频治疗 ,结合彩色及能量多普勒评价其治疗效果。方法 对 12 0例肝癌患者射频治疗前后 1周肿瘤内血供及形态学变化进行观察 ,并对部分病例术后 1个月进行超声检测。结果 12 0例肝癌患者 16 7个肿块术后瘤体缩小 10 3个 (6 1% ) ,血流信号消失 116个 (79% ) ,肝动脉峰值流速明显降低 (89 5±36 0cm/svs 6 3 6± 2 6 0cm/sP <0 0 1)。 1月后对 39例患者复查 ,31例瘤体不同程度缩小 ,瘤体内无血流信号 ;3例再次出现血流信号。结论 超声显像及多普勒技术不但能准确地引导肝癌射频治疗 ,而且对判断疗效及指导再次治疗具有重要意义。
Objective To use ultrasound imaging to guide the radiofrequency treatment of liver cancer, and combine color and power Doppler to evaluate its therapeutic effect. Methods One hundred weeks before and after radiofrequency treatment, the blood supply and morphological changes of the tumors were observed, and some cases were examined by ultrasound one month after operation. RESULTS: The tumor size decreased by 10 3 (6 1%) in 116 patients with hepatocellular carcinoma after surgery. The blood flow signal disappeared by 116 (79%) and the peak flow velocity of the hepatic artery was significantly reduced (89 5±36 0 cm/svs 6). 3 6 ± 2 60 cm/sP <0 0 1). After reviewing 39 patients in January, 31 cases of tumors were reduced in different degrees, and there was no blood flow signal in the tumors; 3 cases showed blood flow signals again. Conclusion Ultrasound imaging and Doppler techniques can not only accurately guide the radiofrequency treatment of liver cancer, but also have important significance in judging the curative effect and guiding retreatment.
