Abstract
Objective:To evaluate the dual-source CT double arterial phases enhanced scan for hepatic artery-portal vein fistulas(HAPVF)and its risk factors analysis.Methods:Sixty patients with HAPVF and sixty patients with non-HAPVF were selected.All patients underwent dual-source CT double arterial phases enhanced scan.The clinical indicators and imaging features were compared between the two groups.DSA findings were used as the gold standards,and the sensitivity and specificity of the early arterial phase,the late arterial phase and the double arterial phases were compared,and the accuracy for HAPVF classification was compared.Logistic regression analysis was applied to explore the risk factors of HAPVF,and ROC curve was used to evaluate the value of the risk factors prediciting HAPVF.Results:The sensitivity,specificity,positive predictive value,negative predictive value and the classification accuracy of the double arterial phases in diagnosis of HAPVF were significantly greater than those of the early and late arterial phases.The tumor size,envelope type and portal vein tumor thrombus were significantly different between the two groups(all P＜0.05),and were all independent risk factors for HAPVF revealed by multivariate regression analysis.ROC curve analysis showed the best single-factor predictor was envelope type,then the portal vein tumor thrombus,and last the tumor size.Multifactor combined forecasting analysis revealed that the combined prediction of the three features was the best.Conclusions:Dual-source CT double arterial phases enhanced scan has the high sensitivity and specificity in the diagnosis of HAPVF,and it has a good diagnostic accuracy in HAPVF classification.Clinical indicators and CT findings of HAPVF include certain characteristics,and tumor size,envelope type and portal vein tumor thrombus are independent risk factors.The combined prediction of the three is the best,which provides a reliable and effective basis for timely clinical diagnosis and treatment.关键词
