目的探讨彩色多普勒血流显像(CDFI)诊断肝癌门静脉癌栓的临床价值。方法回顾性分析50例肝癌门静脉癌栓彩色多普勒超声影像表现,观察肝癌部位、大小、门静脉内部回声及周边血流特点。结果肝癌弥漫型、结节型、巨块型中以前者伴发门静脉癌栓率最高；而门静脉癌栓好发部位依次为主干、左支、右支；门静脉癌栓二维超声表现为门静脉内径增宽,管腔内见局限性或弥漫性实体回声,部分或完全阻塞管腔,门静脉周围尚可出现海绵样变性；CDFI则表现为门静脉血流变细或中断。结论肝癌合并门静脉癌栓有血流动力学的特殊变化,CD-FI诊断肝癌门静脉癌栓是临床首选方法之一。

Objective To evaluate the diagnostic value of and color Doppler flow mi aging(CDFI) in the tumor thrombosis in portal vein. Methods 50 cases of hepatocellular carcinoma with tumor thrombosis in portal vein were retrospectively analyzed. The portal vein diameter, tumor thrombosi size, shape and peripheral blood flows were observed. Results The frequent sites were main portal vein, left portal vein branch, right portal vein branch.Portal vein diameter widen, the portal vein partly or completely blockaged by tumor thrombosis, the blood flowwas thinneror filling defect in tumor thrombosis attachmen evaluated by CDFI. Conclusion: The changes of hepatic hemodynamic in hepatic carcinoma with portal vein tumor thrombus in the diagnosis of the tumor thrombosis in portal vein and regard as one of the preferred method.
