Results and Conclusions The main factors influencing the treatment effect of PHC in China are the followings:(1) Most patients with PHC of subclinical type failed to be diagnosed and treatment in time.(2) As a wrong idea PHC has been considered an "uncurable disease", so the treatment strategy is nagative.(3) Unsuitable choice of treatment resulted in some PHC unable to be resected.(4) Intraoperative massive bleeding due to unskill-operative techniques, increase the postoperative morbidity and mortality.(5) The manner of treatment is not positive for PHC patients with portal cancer thrombosis, bile duct cancer hteombosis and portal hyperlension.(6) Combined therapy can not be used or unsuitably used.

结果与结论影响我国PHC治疗效果的主要因素有：(1)诊断不及时，致使大多数亚临床期病人未及时确诊，丧失了手术良机；(2)观念陈旧，认为肝癌是&不治之症&，治疗态度消极；(3)治疗方法选择不当，使一些本来可以切除的PHC病人错过了手术时机；(4)手术医生技术不熟练，术中出血多，增加了手术后并发症和死亡率；(5)对PHC合并门静脉癌栓，胆管癌栓，门静脉高压症等合并症缺乏积极治疗态度；(6)不重视或不合理应用综合治疗措施等。

Seven cases with portal vein tumor thrombus were diagnosed by CO2-hepatic arterio-sonography (CO2-HAS). Their ultrasonographic features of CO2-HAS were as follows: several seconds after the injection of CO2 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 CO2 contrast injection there were still scattered unflowing bright echoes in tumor thrombus.
