Angiography of pancreatic arteriovenuos malformation

Abstract

Three cases of pancreatic arteriovenous malformation are presented. This entity is known to be a part of Osler-Weber-Rendu disease. However, asymptomatic pancreatic arteriovenous malformation also occurs. The angiographic features are specific and consistent of dilated and tortuous feeding arteries, racemose intrapancreatic vascular network, and early filling veins. Massive gastrointestinal hemorrhage is a frequent complication. The importance of preoperative localization of the lesion and postoperative confirmation of complete resection by angiography is stressed.
