Budd-Chiari syndrome is defined as occlusion of which hepatic vessels?

Budd-Chiari syndrome is an obstruction of hepatic venous outflow. It occurs when the hepatic veins (or their connection to the inferior vena cava) are occluded, usually by thrombosis or external compression, blocking blood from leaving the liver. This causes hepatic congestion, hepatomegaly, ascites, and potential liver dysfunction. The key feature is venous outflow blockage from the liver. Occlusion of the portal vein would impair inflow and produce portal hypertension with different clinical features; inflammation of the bile ducts points to cholangitis or cholestasis; hepatic artery occlusion would cause hepatic ischemia rather than venous congestion.
