Vascular complications associated with pancreatitis and pancreatic surgery occur at a variable frequency depending on the severity of pancreatitis, the presence of necrosis or pancreatic fistula, and the type of surgery.1- 2 Common vascular complications include hemorrhage due to vascular erosion, pseudoaneurysm, and venous thrombosis.3 Although a pseudoaneurysm and venous thrombosis may be asymptomatic, patients often present with abdominal pain, melena, and hypotension due to ongoing bleeding in the gastrointestinal tract, the peritoneal cavity, or the retroperitoneum.4 Expectant management of active hemorrhage is associated with poor outcomes,5 and surgery is often the only choice in patients with significant hemodynamic instability.2 Although surgical intervention may stop the bleeding, postoperative morbidity and mortality rates are high.6- 8 Early reports on endovascular therapy for active hemorrhage in these patients provided variable results.9- 11 Although it is currently the preferred early intervention in hemodynamically stable patients, the long-term outcomes of endovascular therapy are not well described. In addition, the outcomes of patients who have a negative angiographic finding are not known. Herein, we aim to study the outcomes of patients who underwent angiography for a suspected visceral artery pseudoaneurysm in the setting of acute pancreatitis or pancreatic surgery.
