Budd-Chiari syndrome is an example of which liver disease category?

• A. Vascular liver disease
• B. Hepatocellular disease
• C. Obstructive liver disease
• D. Metabolic liver disease

Answer: (A)

Budd-Chiari syndrome is a vascular problem because it stems from obstruction of the hepatic venous outflow, causing congestion of the liver. This vascular obstruction is the primary issue, not hepatocyte injury, biliary blockage, or a metabolic defect. In liver disease categories, vascular liver disease refers to problems with blood flow through the liver, such as hepatic vein obstruction. Hepatocellular disease involves damage to liver cells, obstructive disease concerns bile duct flow, and metabolic disease involves processing or storage of substances; none of those describe the venous outflow obstruction seen in Bud-Chiari. So the vascular classification best fits, reflecting the pathophysiology of impaired venous drainage leading to congestion and related symptoms.
