RT Journal Article SR Electronic T1 Pancreatic pseudocyst causing portal vein thrombosis and pancreatico-pleural fistula. JF Gut JO Gut FD BMJ Publishing Group Ltd and British Society of Gastroenterology SP 561 OP 563 DO 10.1136/gut.31.5.561 VO 31 IS 5 A1 McCormick, P A A1 Chronos, N A1 Burroughs, A K A1 McIntyre, N A1 McLaughlin, J E YR 1990 UL http://gut.bmj.com/content/31/5/561.abstract AB Portal vein thrombosis and pancreatico-pleural fistula are unusual complications of chronic pancreatitis. We describe a patient with chronic alcoholic pancreatitis in whom erosion of the splenic vein led to portal vein thrombosis and to the development of a pancreatico-pleural fistula. We suggest that fistula formation may occur over a considerable time period as the portal vein thrombosis was diagnosed three years before the amylase-rich pleural effusions.
