摘要
分析了８０例由肝细胞癌（ＨＣＣ）引起的门静脉主干癌栓的病例，提出主干癌栓的病例均有门静脉左支和／或右支癌栓存在。其主要ＣＴ表现除门静脉主干及分支内为无增强的低密度外（１００％），还见主干旁和肝门区侧支血管形成（９３．８％），部分出现管壁环状增强（１７．５％）和主干内新月状增强影（３２．５％）。另外，主干内癌栓可延续至肠系膜上静脉（７．５％）；门静脉主干癌栓形成后出现腹水的比例较高，同时对门静脉主干癌栓的形成和各种表现产生的机理，以及与ＨＣＣ的类型关系作了讨论。
caese of hepatocellular carcinoma(HCC) with tumoral thrombosis in the portal stem vein(PSV)were studied.CTdemonstrated that tumoral thrombosis in PSV was associated invariably with involvement of left or right or both branches in all cases,Hypodence filling defect was the principal finding of the tumoral thrombosis in the postcontrast scan,Suth patients had ascites in high percentage(93.8%).The enhancement of the wall of the PSV(17.5%),cresence-like enhancement at the end of the stem(32.5%)and extention of the tumoral thrombosis into the superior mesenteric vien(7.5%) were seen,The mechanism of the development of tumoral thrombosis and its variable CT appearances,also the relationship between the tumoral thrombosis in PSV and the pathological types of HCC were analysed.
