Analysis of the risk factors of portal vein thrombosis in liver cirrhosis patients

Objective To research the risk factors of portal vein thrombosis (PVT) in liver cirrhosis patients. Methods Eighty cirrhotic patients with (n=19) or without (n=61) PVT diagnosed during 2007 to 2008 in our Dept. were enrolled. Seventeen common ultrasonographic and serum markers were analyzed. SPSS software was used for statistic analysis. Results Logistic regression model analysis showed that D-dimer,main portal vein width and platelet were the independent risk factors of portal vein thrombosis (PVT) in liver cirrhosis patients. Conclusion D-dimer,main portal vein width and platelet should be monitored in patients with cirrhosis to prevent the occurrence of portal vein thrombosis.
