Pathogenesis

Etiology

Pathophysiology

  • Cumulative hepatic insult → functional reserve capacity exceeded (>70% damage) → failure to perform diverse metabolic functions → clinical signs.
  • Increased resistance to blood flow through liver due to hepatocytes swelling → development of portal hypertension →ascites. Ascites may also develop due to hypoalbuminemia Hypoproteinemia.
  • Acquired shunting vessels may develop due to sustained portal hypertension.
