肝静脉阻塞型布-加氏综合征的超声诊断价值

目的:探索彩色多普勒超声对肝静脉阻塞型布-加氏综合征的诊断价值.材料和方法:应用彩色多普勒超声观察138例肝静脉阻塞型布-加氏综合征的彩色多普勒超声的声像图特点, 并与血管造影对比分析. 结果:肝静脉隔膜型阻塞83 例(60.1 %),节段性闭塞45 例(32.6 %),单纯狭窄10例(7.3 %).表现为肝静脉流出道有狭窄、闭锁、栓子或隔膜梗阻图像,肝静脉间可见交通支形成,肝短静脉代偿性扩张,第三肝门开放等.同时存在肝静脉和下腔静脉阻塞者35例,合并下腔静脉血栓者11例,肝静脉血栓7例.超声诊断假阳性2例,假阴性3例.结论:彩色多普勒超声可较准确地判定肝静脉血管狭窄及闭塞的部位和类型,并明确血管梗阻的程度及侧支血管形成情况,有助于手术方式的选择以及术后疗效的判断.

Ultrasounic Diagnosis of Budd-Chiari Syndrome with Hepatic Venous Outflow Obstruction

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.
