中文摘要：

研究肝硬化患者门静脉血栓（ PVT）形成的多种危险因素。回顾性分析肝硬化患者110例,其中39例肝硬化PVT患者作为PVT组,71例肝硬化未合并血栓患者作为对照组,收集相关临床资料,对可能影响PVT形成的因素进行单因素分析和Logistic回归模型分析。单因素分析和Logis-tic回归模型分析结果显示纤维蛋白原是肝硬化PVT形成的独立危险因素（P=0.002,P=0.031）。肝硬化患者应注意监测纤维蛋白原以便早期发现和预防PVT的形成。

英文摘要：

To research the risk factors of portal vein thrombosis（ PVT） in liver cirrhosis patients. 110 cirrhotic pa-tients with （ n =39 ） or without （ n =71 ） PVT diagnosed were enrolled. 12 common ultrasonographic and serum markers were analyzed. SPSS software was used for statistic analysis. Single factor analysis and Logistic regression model analysis showed that fibrinogen was the independent risk factor of portal vein thrombosis（ PVT） in liver cir-rhosis patients. Fibrinogen should be monitored in patients with cirrhosis to prevent and find the occurrence of portal vein thrombosis.
