Introduction : Pseudoaneurysm of visceral arteries is uncommon and usually provoked by intraabdominal inflammary processes such as pancreatitis or cholecystitis , or by surgical trauma. Vascular complication of pancreatitis are major cause of morbidity & mortality, including haemorrhage from direct arterial erosion or pseudoaneurysm formation, splanchnic vein thrombosis and visceral ischemia . Pseudoaneurysm formation in pancreatitis might related to autodigestion of pancreatic enzymes, especially elastase, liberated due to pancreatitis.
