【摘要】 目的 研究原发性肝癌合并门静脉癌栓时门静脉和肝动脉的超声表现和血流动力学变化。方法 应用超声分别研究肝癌合并门静脉癌栓组(癌栓组)和对照组门静脉、肝动脉的二维和多普勒超声改变及血流动力学各项指标。结果 癌栓组较对照组门静脉内径明显增高，流速降低(P<0.05)，肝动脉显示率和流速明显提高(P<0.05)。结论 应用彩超检查获得肝癌合并门静脉癌栓肝内血流的重要指标，对诊断、指导治疗和判断预后有重要意义。【关键词】 原发性肝癌；门静脉癌栓；肝动脉

【Abstract】 Objective To study the changes of liver blood flow before and after portal vein thrombus(PVT)of hepatocellular carcinoma.Methods The diameter and the velocity of hepatic arterial (HA) and portal vein (PV) before and after portal thrombosis of hepatocellular carcinoma were measured with color Doppler flow imaging.Results The diameter of PV dilated and the velocity of PV dropped significantly.The velocity of HA increased obviously.Conclusion The parameter of HA and PA is very important to guide the therapy and judge prognosis of hepatocellular carcinoma. ......
