原发性肝癌合并门静脉癌栓的临床分析

Clinical Analysis of Primary Hepatocellular Carcinoma(HCC) Complicated by Tumor Thrombus in Hepatic Portal Vein

目的探讨原发性肝癌门静脉癌栓(PVTT)形成的相关因素。方法回顾分析原发性肝癌243例,64排螺旋CT检查PVTT,总结PVTT与肝癌大体类型、肝硬化基础的相关性。结果 243例肝癌病例中合并门静脉癌栓98例,有肝硬化基础者PVTT发生率显著高于无肝硬化基础者;癌栓类型和肝癌大体类型及肿瘤中心位置无明显相关性。结论有肝硬化基础的原发性肝癌患者易形成门静脉癌栓。

Objective To discuss the related factors of the primary HCC complicated by portal vein tumor thrombus（PVTT）. Methods Retrospective analysis of 243 cases of the primary HCC patients was conducted,which was based on diagnosis of 64 multidetector spiral CT.Then we summarized the relevance of PVTT to the gross type of HCC and cirrhosis. Results 98 cases of HCC complicated with PVTT occurred in 243 cases of HCC,incidence of PVTT based on liver cirrhosis was higher than that of without cirrhosis.No clear relevance was observed between the types of tumor thrombus and the gross types of HCC or the central locations of tumors. Conclusion It is easier to develop PVTT for patients of primary HCC complicated with cirrhosis.
