Definition / general
  • Usually irreversible injury of hepatic allografts, likely secondary to ischemic damage to hepatocytes or direct immunologic damage to bile ducts with total loss (vanishing bile duct syndrome)
  • May have insidious onset with no acute component
Microscopic (histologic) description
  • Vanishing bile duct syndrome: loss of intrahepatic bile ducts, minimal portal inflammation
  • Obliterative endarteritis: occlusion by subintimal fibrosis and foam cell change in large and medium sized hilar hepatic arteries and portal vein and distal branches near hilum
  • Also associated ischemic changes of centrilobular ballooning degeneration, pericellular fibrosis and possibly cirrhosis
  • Changes more variable in portal vein
  • Pathognomonic arterial changes are rarely present in needle biopsies
