The present study was undertaken to define the role of ultrasonography (US) in screening and diagnosis of hepatic venous outflow tract obstruction. Forty-five consecutive patients clinically suspected to have hepatic venous outflow tract obstruction were included in the study for screening by US and for assessment of patency or block in the hepatic vein (HV) and/or inferior vena cava (IVC). Four patients were excluded from the study. Eleven patients had a diagnosis other than hepatic venous outflow tract obstruction and all these patients were found to have patent HV and IVC. Thirty patients were finally diagnosed to have hepatic venous outflow tract obstruction. Using US, as a screening test 27 (90%) out of 30 such cases were correctly identified as cases of hepatic venous outflow tract obstruction and in these cases the site of block in hepatic venous outflow tract (major HV and/or IVC) was correctly diagnosed in 90% of the cases. Our results indicate that US is a sensitive and accurate test and should be the initial investigation for screening and identifying the site of obstruction in patients with hepatic venous outflow tract obstruction.
本研究旨在明确超声检查（US）在肝静脉流出道梗阻筛查及诊断中的作用。45例临床怀疑患有肝静脉流出道梗阻的患者纳入本研究，接受US筛查，并评估肝静脉（HV）和/或下腔静脉（IVC）的通畅情况或阻塞情况。4例患者被排除在研究之外。11例患者的诊断并非肝静脉流出道梗阻，所有这些患者的HV和IVC均通畅。最终30例患者被诊断为肝静脉流出道梗阻。使用US作为筛查试验，30例此类病例中有27例（90%）被正确识别为肝静脉流出道梗阻病例，在这些病例中，90%的病例正确诊断出肝静脉流出道（主要HV和/或IVC）的阻塞部位。我们的结果表明，US是一种敏感且准确的检查，应作为肝静脉流出道梗阻患者筛查和确定梗阻部位的初始检查。
