Ischemic Gastritis: A Rare Case of Acute and Chronic Etiology

* Ischemic gastritis can be secondary to both acute and chronic injury.

* Certain circumstances are amenable to a non-surgical con- servative treatment approach.

Conclusion:

Background:

* The abundant vascular supply of oxygenated blood to the stomach via major arteries and smaller collateral vessels provides resistance to mucosal ischemia.

* However, changes can occur in the acute vaso- occlusive setting after a major operative procedure, or with chronic mesenteric insufficiency.

* Gastric ischemia can be quite severe and, in the presence of necrosis, causes significant morbidity.

* A common diagnostic and treatment modality is surgery.

Pathology:

Gastric biopsy, Hematoxylin and Eosin stain 100x: Mucosal necrosis, consistent with ischemia.

Gastric biopsy, Hematoxylin and Eosin stain 40x: Superficial mucosal necrosis with lamina

propria hemorrhage, consistent with ischemia.
