Ultrasounic Diagnosis of Budd-Chiari Syndrome with Hepatic Venous Outflow Obstruction / 中国医学影像学杂志

ABSTRACT

Purpose:The aim of this study was to investigate the diagnostic value of color Doppler Ultrasound in Budd-Chiari Syndrome (BCS) with hepatic venous(HV) outflow obstruction.Materials and Methods:The features of ultrasonography in 138 patients of Budd-Chian Syndrome were analyzed and compared with that of angiography.Results:83 patients had membranous obstruction and 45 segmental occlusion of HV.10 patients had HV stenosis.The ultrasound was able to reveal stenosis,atresia,emboli,or membranous obstruction in hepatic venous outflow tract.Collateral branches could be seen between the hepatic veins with short hepatic vein expanded.Both HV and IVC were involved in 35 cases,with thrombus in IVC in 11 and HV in 7.There was two false positive cases and 3 false negative in ultrasound diagnosis.Conclusion: The position and type of occlusion in HV could be accurately detected by color Doppler ultrasound,and so was the existence and degree of collateral circulation,which were of aid for the operation and follow-up.
