Diagnostic and Therapeutic Challenges in Hemosuccus Pancreaticus: A Case Report.

Hemosuccus pancreaticus, also known as pancreatic pseudoaneurysm, is a rare type of upper gastrointestinal bleeding that originates from the major duodenal papilla or ampulla of Vater and extends into the duodenum via the pancreatic duct. By 2021, only 150 cases had been reported worldwide. Without treatment, the mortality rate can be as high as 90%, but it drops to 25%-37% with intervention. We report a case of a 64-year-old woman who experienced intermittent upper gastrointestinal bleeding over a year. Imaging revealed a hematoma and pseudoaneurysm in the pancreas, which was successfully treated with angiographic embolization. This case highlights the value of a multidisciplinary approach, using advanced imaging and minimally invasive techniques like embolization for effective patient outcomes.
