Gastroduodenal Artery Pseudoaneurysm Causing Upper Gastrointestinal Bleeding.

Gastroduodenal artery pseudoaneurysms (GDAPs) are a rare but potentially life-threatening condition characterized by the formation of a blood-filled sac secondary to disruption of the arterial wall, frequently resulting from trauma, pancreatitis, or ulceration. We present the case of a 73-year-old female diagnosed with a GDAP of unknown etiology. Management included collaboration with the interventional radiology team for angiography and coil embolization. This case highlights the importance of early recognition and multidisciplinary management, including imaging, endovascular intervention, and surgical consideration.
