Gastrointestinal bleeding due to chronic portal vein thrombosis in ulcerative colitis.
The authors report the case of a patient suffering from ulcerative colitis, who had several episodes of digestive hemorrhage due to portal hypertension. Portal hypertension was secondary to chronic portal vein thrombosis. This diagnosis was made on the venous phase of celiac and mesenteric angiography. The authors review the published cases of ulcerative colitis with portal vein thrombosis and discuss the possible etiologic factors: hypercoagulability, thrombocytosis, and intraabdominal sepsis.
