Gastric Antrum

Gastric Antrum: Gastric Antral Vascular Ectasia or GAVE is a rare origin of gastrointestinal bleeding that is chronic as well as anemia from the loss of blood. This condition is associated with small blood vessels dilating in the gastric antrum. The dilated vessels cause intestinal bleeding. It is likewise referred to as “watermelon stomach” because of long streaky areas of red in the stomach that many believe look like the markings on watermelon.

This condition involving the last portion of the stomach which is known as the “gastric antrum”, was first written about in 1952, and reported in medical literature in 1953. As of 2011, the pathogenesis and etiology are still unknown; however, there are several opposing hypotheses as to several etiologies.
