title: Enterovenous fistula: unusual complication of Crohn disease.
abstract: An unusual complication in a patient with Crohn enterocolitis is presented. Ultrasound and computed tomographic studies showed stationary gas in the portal vein, and a presumptive diagnosis of septic ascending portal thrombophlebitis was made. Emergency laparotomy was performed and the terminal ileum was excised for recurrent Crohn disease. Pathologic examination showed a fistula from the lumen of the inflamed segment to the superior mesenteric venous system. Autopsy 1 month later showed organizing thrombi and fecal debris in the portal venules.
