Splenic Artery Pseudoaneurysm Causing Massive Hematemesis 10 Years After Necrotizing Pancreatitis.

We report a case of a 54-year-old male presenting to a regional hospital with severe hematemesis and hemodynamic instability. His medical history was significant for a previous episode of alcoholic necrotizing pancreatitis and pseudocyst, requiring cystoenterostomy drainage and debridement 10 years prior. He underwent multiple gastroscopies and one emergency laparotomy which failed to definitively treat the bleeding. A splenic artery pseudoaneurysm was diagnosed with computed tomography angiography, adjacent to the previous cystoenterostomy site. The patient was transferred to a major tertiary center with access to interventional radiology and underwent successful embolization of the pseudoaneurysm.
