Treatment of a Pancreatic Pseudoaneurysm with Percutaneous image-guided Transhepatic Thrombin Injection – Case Report

Pancreatic pseudoaneurysms represent a rare but life-threatening vascular complication of both acute and chronic pancreatitis. The Society for Vascular Surgery and CIRSE (Cardiovascular and Interventional Radiological Society of Europe) underscore the necessity of prompt and definitive treatment for both symptomatic and non-symptomatic, aneurysms and pseudoaneurysms of pancreaticoduodenal and gastroduodenal arteries, regardless of size or anatomical location [1] [2]. Pathogenesis is most commonly linked to arterial wall erosion, typically of a peripancreatic or pancreatic artery, frequently resulting in hemorrhage into a pseudocyst, although pseudocyst formation is not a prerequisite for pseudoaneurysm development [3].
