title: [Colonic varices; a case report].
abstract: Colonic varices is a rare entity that is caused by portal hypertension in most instances. In the case reported here, barium enema and colonoscopy showed multiple tortuous polypoid lesions with intact mucosal surface. Inferior mesenteric angiography showed arteriovenous malformation in the sigmoid colon, complete obstruction of the inferior mesenteric vein, and tortuous dilated marginal veins. We assume that the colonic varices of this case was secondary to complete obstruction of the inferior mesenteric vein following AVM of the sigmoid colon. Close follow-up should is warranted in cases of colonic varices because of the risk of bleeding.
