Introduction:
Acute upper gastrointestinal bleeding is a common emergency presentation. The United States Centers for Disease Control and Prevention 2018 survey of emergency department (ED) visits reported 436,000 ED visits for unspecified gastrointestinal bleeding that year.
Case Report:
We present the case of a submucosal duodenal pseudoaneurysm causing massive gastro-intestinal hemorrhage in a male on anticoagulation.
Conclusion:
Prompt recognition of critical gastrointestinal bleeding, appropriate ED management, and early consultation for emergent intervention are the essential components to reduce morbidity and mortality for patients with massive gastrointestinal hemorrhages.
