The Occurrence of a Pseudoaneurysm of the Hepatic Artery within the Thrombosed Portal Vein of a Patient with Chronic Pancreatitis: A Case Report

lar complications including thromboses of the portal venous system and the formation of a pseudoaneurysm. Pseudoaneurysms occur in approximately 3.5-10.0% of patients with pancreatitis (1). The arteries most commonly affected by pseudoaneurysms are (in decreasing percent occurrence), the splenic (40%), gastroduodenal (30%), pancreaticoduodenal (20%), gastric (5%), hepatic (2%), and others (superior mesenteric, jejunal, ileocecal, and aorta) (1-3%) (1, 2). Thrombosis of the portal venous system is another important complication of chronic pancreatitis (1, 3). An isolated splenic vein thrombosis is more common than a portal or superior mesenteric vein thrombosis in patients with chronic pancreatitis (1). However, as far as we know, a pseudoaneurysm within the thrombosed right portal vein of a patient with chronic pancreatitis has been not reported. In this case report, we present the case of a right hepatic artery pseudoaneurysm which developed within the thrombosed right portal vein of a 35-year-old woman afflicted with chronic pancreatitis.
