In a series of 19 patients with Budd-Chiari syndrome, transhepatic venography and inferior vena cavography were used to localize the site of hepatic outflow obstruction. Classification into two types was made on the basis of the site of obstruction. Four cases were grouped as type I, in which obstruction was localized in the hepatic vein alone, and the inferior vena cava (IVC) was patent. Fifteen cases were of type II, in which there was a well-defined obstruction in the intrahepatic portion of the IVC or ostium of a hepatic vein. This study highlights the frequent occurrence of IVC obstruction as a cause of chronic Budd-Chiari syndrome in northern India and the utility of transhepatic venography in its diagnosis.
在一组19例布加综合征患者中，采用经肝静脉造影和下腔静脉造影来定位肝静脉流出道梗阻的部位。根据梗阻部位将其分为两型。4例归为I型，梗阻仅局限于肝静脉，下腔静脉通畅。15例为II型，下腔静脉肝内段或肝静脉开口处存在明确梗阻。本研究强调了在印度北部下腔静脉梗阻作为慢性布加综合征病因的常见性以及经肝静脉造影在其诊断中的实用性。
