摘要 应用二氧化碳(CO2)肝动脉造影诊断7例门静脉癌栓,其造影增强声像图表现为:注射CO2微泡造影剂数秒钟后即可见癌栓光团弥漫性光点闪动,似白云翻滚或门脉实体回声内有数条和门静脉管径长轴平行的微气泡光带流动,停止注射后门静脉实体回声内仍有弥漫性非流动性增强光点,持续时间较长。因而可和正常时门静脉管腔呈暗区及肝动脉-门静脉瘘时门静脉内流动性光点相鉴别。我们认为CO2肝动脉超声造影对确诊门静脉癌栓及门静脉癌栓治疗方案的设计有重要作用。 WT5”BZ〗Seven cases with portal vein tumor thrombus were diagnosed by CO 2 hepatic arterio sonography (CO 2 HAS). Their ultrasonographic features of CO 2 HAS were as follows: several seconds after the injection of CO 2 microbubble contrast, bright cloudy flowing echoes or several flowing echo stripes along the long axis of portal vein were seen in tumor thrombus. During interrupted phase of CO 2 contrast injection there were still scattered unflowing bright echoes in tumor thrombus. These could be distinguished from the echo-free normal portal vein or the continuosly flowing echo in hepatic arterio-portal vein shunt. It is concluded that CO 2-HAS is helpful to diagnose and design the therapeutic regimen of portal vein tumor thrombus. [WT5”HZ〗
