摘　　要：目的:探讨原发性肝癌门静脉癌栓螺旋CT双期增强扫描表现。材料与方法:对36例门静脉癌栓患者行螺旋CT双期增强扫描,观察门静脉癌栓在CT上的表现。结果:36例TTPV患者在螺旋CT动态增强扫描时均显示出门静脉内癌栓及相关的阳性征象,表现为门静脉扩张、门静脉腔内充盈缺损及"门静脉铸型",门静脉周围可见网状供血动脉。36例中,门静脉主干合并右支癌栓12例,门静脉主干合并左支癌栓8例,主干和左右支均有癌栓者9例,单纯右支癌栓4例,单纯左支癌栓3例。结论:螺旋CT双期增强扫描是诊断门静脉癌栓的有效方法,可以完整地提供门静脉癌栓的全部资料。Purpose： To evaluate the CT appearance of biphasic contrast enhancement of tumor thrombus of the portal vein in primary hepatic carcinoma. Materials and Methods： Dual - phase enhanced spiral CT scans were perfomed in 36 patients with tumor thrombus of the portal vein, the appearance of tumor thrombus of the portal vein in primary hepatic carcinoma were analyzed. Results： All the 36 patients with TrPV had positive CT findings related to TrPV, which were dilation of portal vein（PV）, filling defect within PV and ＂PV casting＂, network artery in surroundings of PV. in the 36 cases, pertal trunk with right portal branch in 12 cases, portal trunk with left portal branch in 8 cases, and tumor thrombus of the portal trunk with left and right portal branch in 9 cases, right portal branch in 4 cases, left portal branch in 3 eases. Conclusion： biphasic contrast enhancement is valuable to diagnose tumor thrembus of the portal vein in primary hepatic carcinoma, it can provide a comprehensive information about the tumor thrombus of the portal vein.
