Abstract:
A 14-year-old boy presented with several months of increasing abdominal girth and fatigue. Imaging confirmed massive ascites and hepatic congestion secondary to central hepatic venous obstruction. Several large intrahepatic collateral veins were seen draining via caudate and emissary veins. After an unsuccessful attempt at retrograde recanalization utilizing intravascular ultrasound, the right hepatic vein was recanalized in an antegrade fashion by way of a prominent caudate collateral vein, and subsequently stented. We herein discuss the established treatment options for Budd-Chiari syndrome and describe our experience employing a single-access liver floss technique.
