目的探讨彩色多普勒超声(CDFI)在射频消融联合经皮瘤内注射无水乙醇治疗转移性肝癌的临床价值。方法利用彩色多普勒超声观察了84例射频联合经皮瘤内注射无水乙醇治疗转移性肝癌前后肿瘤的血供变化与临床疗效的关系。结果治疗一个月后瘤周及瘤内血流信号消失或减少96.6%,其中完全消失达64.7%。1、2、3年生存率分别为66.7%,58.2%、41.9%。结论彩色多普勒超声对判断疗效及指导再次治疗具有重要意义。
Objective To investigate the clinical value of color Doppler ultrasound (CDFI) in radiofrequency ablation combined with percutaneous intratumoral injection of absolute ethanol in the treatment of metastatic liver cancer. Methods 84 cases of radiofrequency combined with percutaneous intratumoral injection of ethanol in the treatment of metastatic liver cancer before and after the change of blood supply and the relationship between the clinical efficacy of color Doppler ultrasound. Results One month after treatment, the tumor and tumor blood flow signals disappeared or decreased by 96.6%, of which 64.7% disappeared completely. The 1, 2, 3-year survival rates were 66.7%, 58.2% and 41.9% respectively. Conclusion Color Doppler ultrasound is of great significance in judging the curative effect and guiding the re-treatment.
