Mesenteric venous infarction presenting as an upper GI bleeding and diagnosed by upper GI endoscopy

Area of Science:

• Gastroenterology
• Vascular Surgery

Background:

• Primary mesenteric vein thrombosis is a rare condition.
• Upper gastrointestinal bleeding can be a presenting symptom.

Observation:

• A case presented with upper GI bleeding and erosive gastritis.
• Endoscopic examination revealed necrotic duodenal mucosa near the ligament of Treitz.

Findings:

• The extensive small bowel infarct was attributed to mesenteric vein thrombosis.
• Necrotic duodenal mucosa indicated severe ischemia.

Implications:

• Highlights the importance of advanced endoscopic evaluation beyond the stomach.
• Suggests considering mesenteric vein thrombosis in unexplained upper GI bleeding.
• Emphasizes thorough duodenal examination when gastric findings are insufficient.
