Portal Hypertensive Gastropathy

Definition

  • Gastric vascular changes associated with portal hypertension

Diagnostic Criteria

  • Dilated, tortuous vessels in submucosa of gastric body
    • May not be visible on shallow biopsy specimens
    • Mucosal vascular distension
    • Nearly always associated with portal hypertension due to cirrhosis
  • Endoscopic appearance
    • Cherry red spots
      • May resemble scarlatina rash
    • White reticular pattern
      • May resemble snakeskin
    • Mosaic appearance in proximal stomach
  • Responds to lowering of portal pressure

Secondary to cirrhosis May be associated with cirrhosis
No microthrombi Microthrombi characteristic
No fibromuscular change or hyalinization in lamina propria Fibromuscular hyperplasia with hyalinization of lamina propria
