【摘要】 目的　应用彩色多普勒测定肝癌患者介入治疗 (TAE)术前后血流指数的改变 ,为评估术后疗效及预后提供依据。方法　对 58例原发性肝癌患者使用彩色多普勒超声 ,于介入治疗术前 5～ 7天及术后 7～ 1 0天、6个月和 1 2个月测定病灶内彩色动脉型血流的最大流速 (PSV)及阻力指数 (RI)。结果　TAE后肿瘤内径缩小 ,PSV下降 ,RI增高 ,但生存期 <1年组栓塞后 6月PSV、RI改变并不显著 ,与生存期>1年组相比有显著差异 (P <0 .0 1 )。结论　原发性肝癌患者在介入治疗后 ,癌肿内血流动力学发生不同程度变化 ,是评估预后的重要因素。更多还原

【Abstract】 Objective To observe color Doppler changes of hemodynamic indices before and after transhepatic artery embolization (TAE) and supply evidence for effect and prognostic evaluation in treatment of hepatocellular carcinoma. Methods Peak systolic velocity (PSV) and resistance index (RI) of color arterial flow in tumor were measured 5-7 days before TAE and 7-10 days, 6months ,12months after TAE Results The diameter of tumor and PSV decreased, RI increased after TAE, but in the group whose lifetime was less than one year, the PSV ,RI did not change significantly 6 months after TAE. Compared with groups whose lifetime was more than one year, the difference was significant. Conclusion There were different changes of hemodynamics in tumor after TAE, the changes of hemodynamic index were important factors of prognosis of hepatocellular carcinoma.更多还原
