Vascular pseudoaneurysms are a rare yet life-threatening complication of untreated pancreatic pseudocysts related to their high risk of rupture and bleeding. Several studies and reports have established endovascular approaches as a successful first-line therapy in the management of arterial pancreatic pseudoaneurysms. However, no reports have been published describing endovascular repair of a venous pseudoaneurysm that developed after infection of a chronically stable pancreatic pseudocyst, most likely due to its rare occurrence. We report in this technical note the treatment of a superior mesenteric vein pseudoaneurysm that developed as a result of an infected small pancreatic pseudocyst, by radiologic placement of a covered endovascular stent.
