Background: Gastrointestinal vascular malformations are rare and challenging-todiagnose causes of gastrointestinal bleeding, accounting for 5% of non-variceal upper gastrointestinal hemorrhages. We describe a clinical case of a young female patient with superior mesenteric arteriovenous malformation accompanied by a fistula leading to severe gastrointestinal bleeding.
