Intrahepatic and/or extrahepatic collateral pathways result from the membranous obstruction of the inferior vena cava. These collaterals are usually insufficient to prevent Budd-Chiari syndrome. We reprot an unusual case of asymptomatic membranous obstruction of the inferior vena cava in which marked intrahepatic collateral pathways were formed. Although the inferior vena cava terminated above the orifice of the right hepatic vein, the middle and left hepatic veins were patent above the membrane, without narrowing. Blood from the inferior vena cava drained into the right atrium via the intrahepatic collaterals between the right and middle hepatic veins without resistance.
肝内和/或肝外 collateral 途径是由下腔静脉膜性梗阻引起的。这些 collateral 通常不足以预防布加综合征。我们报告了一例罕见的无症状性下腔静脉膜性梗阻病例,其中形成了明显的肝内 collateral 途径。尽管下腔静脉在右肝静脉开口上方终止,但肝中静脉和肝左静脉在膜上方通畅,无狭窄。下腔静脉的血液通过肝右静脉和肝中静脉之间的肝内 collateral 无阻力地流入右心房。
