Gastroduodenal Artery Pseudoaneurysm: A Rare Cause of Upper Gastrointestinal Bleeding and Pancreatic Duct Compression.

Visceral artery pseudoaneurysm as a cause of upper gastrointestinal bleeding is a rare occurrence. These pseudoaneurysms occur most commonly in the splenic artery but have been reported in the gastroduodenal artery as well, albeit with a high mortality rate in cases of rupture. We present a case of a gastroduodenal pseudoaneurysm presenting with upper gastrointestinal bleeding and causing a mass effect on the pancreatic duct as well.
