Gastric Antral Vascular Ectasia: The Invaluable Role of the Gastric Biopsy in its Detection and Confirmation
Gastric vasculopathies consist predominantly of two entities:
- Gastric antral vascular ectasia (GAVE)
- Portal hypertensive gastropathy (PHG)
The classically described GAVE patient is an elderly woman with iron-deficiency anemia and a “watermelon” appearance of the gastric mucosa on endoscopy.
There are two published histologic scoring systems:
- Gilliam et al. (1989) – Devised a system requiring vascular abnormality (thrombi/ectasia) and spindle cell proliferation of the lamina propria to distinguish GAVE from normal, acute gastritis, and atrophic gastritis.
- Payenet al. (1995) – Devised a similar system using vascular abnormality, spindle cell proliferation, and fibrohyalinosis to distinguish GAVE from PHG in cirrhotic patients.
