How is gastric antrum vasodilatation caused

Gastric antral vasodilatation may be caused by portal hypertension, gastric mucosal prolapse, mesenteric obstruction, etc.

1. Portal hypertension,

cirrhosis, heart failure, etc. may cause portal hypertension, and excessive portal pressure may cause gastric mucosal vasodilatation, resulting in gastric antral vasodilatation.

2. Gastric mucosal prolapse,

gastric duodenal lesions may lead to gastric mucosal edema, gastric mucosal prolapse, resulting in gastric mucosal vasodilatation, resulting in gastric antral vasodilatation.

3. Mesenteric obstruction

Foreign bodies, tumors, intestinal torsion, etc. may cause mesenteric obstruction, mesenteric obstruction may lead to compensatory vasodilatation of intestinal mucosa, resulting in gastric antral vasodilatation.
