Title: Dynamic contrast-enhanced CT in diagnosis of hepatic veno-occlusive disease
Abstract: Objective:To study the dynamic contrast-enhanced CT findings of hepatic veno-occlusive disease(HVOD) and evaluate its usefullness in diagnosis of this disorder by using multi-slice spiral CT.Methods:Twelve patients with pathologically and clinically confirmed HVOD were recruited.All CT images were reviewed and the imaging features of the disease were summarized.Results:On plain CT scan,the liver volume increased and the parenchyma appeared localized or diffuse hypodense in 12 patients.On hepatic arteral phase scans,the widening of the common hepatic artery and its main branches in association with disordered reticular intrahepatic vessels were found in 10 patients,and in 2 of the 10 cases,the hypodense parenchyma showed no abnormal enhancement compared with the unenhanced phase.On portal venous phase,hepatic parenchyma demonstrated pathy or map-like heterogeneous enhancement in 9 patients,no intrahepatic venule was noted,while the hepatic inferior vena cava of 5 in the 9 cases manifested comma-shaped,and the other 4 presented narrowed lumen like short strip.No visible distal dilatation or collateral formation was observed.The major hepatic veins,with obviously small diameter,were slightly opacified in only 3 patients.On hepatic parenchymal phase,the imaging findings of liver were similar to those on portal venous phase.Conclusion:HVOD has characteristic features on multi-slice spiral CT scans.Combined with clinical manifestations and history,CT can improve the diagnosis rate of the disease.
