Hemosuccus Pancreaticus Originating From the Left Gastric Artery: A Rare Cause of Upper Gastrointestinal Bleeding

We present the case of a 61-year-old male with a history of chronic alcohol-related pancreatitis who consulted for melena. Abdominal CT angiography and arteriography showed evidence of a pseudoaneurysm of the left gastric artery (upper arrows) with active bleeding towards the pancreatic duct (lower arrow) (Fig. 1). Arteriography with coil embolization of the afferent and efferent branches completely excluded the pseudoaneurysm. The patient's clinical evolution was correct.

Hemosuccus pancreaticus occurring after the rupture of a pseudoaneurysm of a peripancreatic artery towards the pancreatic duct is a potential cause of gastrointestinal bleeding in cases of acute or chronic pancreatitis.
