Angiography of Massive Hemorrhage Secondary to Pancreatic Disease

Abstract

Twenty patients with massive abdominal hemorrhage related to chronic pancreatitis, pancreatic neoplasms and arteriovenous malformations were studied angiographically. Abdominal hemorrhage drained most frequently into the gastrointestinal tract, but also flowed through cutaneous drain sites and fistulas, intraperitoneally, into pseudocysts and once into a large pancreatic tumor. The most common angiographic observation in pancreatitis was pseudoaneurysm formation. Both patients with arteriovenous malformation had dilated, racemose feeding arteries and early dense filling of the draining veins. Three patients had pancreatic carcinoma and documented bleeding from gastroesophageal varices related to portal or splenic vein occlusion by the tumor. Five patients were treated by vasopressin infusion, balloon tamponade, or therapeutic embolization.
