Definition / general
  • Due to obstruction to inflow (hepatic artery or portal vein) or outflow (central veins, major hepatic veins, inferior vena cava, congestive heart failure) or severe hypotension
  • Normal liver is resistant to ischemia due to dual inflow and possibly also collaterals
  • Obstruction of outflow causes central passive congestion, leading to hepatocellular atrophy and centrilobular fibrosis that may obliterate central vein lumina
  • Causes of outflow obstruction: radiotherapy, alkylating agents, comfrey tea
