彩色多普勒血流显像(CDFI)及脉冲多普勒(PW)能通过门静脉及其周围血流的形态变化,不仅可以定性,而且可以判断门静脉癌栓的堵塞程度以及门静脉断流后侧枝循环是否形成等。本文总结了34例原发性肝癌合并门静脉癌栓的门静脉血流的形态变化,旨在探讨CDFI及PW对门静脉癌栓诊断的应用价值。 1 资料与方法 1.1 一般资料本组门静脉癌栓34例,男29例,女5例,年龄31岁～67岁。有肝硬化病史22例。所有病例均经CT、彩超确诊,其中1例为肝动脉栓塞治疗后,1例肝左叶切除后。 1.2 方法使用Acuson 128XP/10彩色超声显像仪。患者空
Color Doppler Flow Imaging (CDFI) and Pulse Doppler (PW) can not only be qualitative but also determine the degree of clogging of the portal vein tumor thrombus and the posterior branch of the portal vein after passing through the morphological changes of the portal vein and surrounding blood flow. Whether the loop is formed or not. This article summarizes the morphological changes of portal vein blood flow in 34 cases of primary hepatocellular carcinoma with portal vein tumor emboli, aiming to investigate the value of CDFI and PW in the diagnosis of portal vein tumor emboli. 1 Materials and Methods 1.1 General Information The group of 34 cases of portal vein tumor emboli, 29 males and 5 females, aged 31 to 67 years old. There are 22 cases of liver cirrhosis. All cases were diagnosed by CT and color Doppler ultrasound, of which one case was treated with hepatic artery embolization and one case was followed by left hepatectomy. 1.2 Method Acuson 128XP/10 color ultrasound imaging system was used.
