[Diagnostic angiography in life-threatening colonic hemorrhage in Crohn disease].

Abstract

Life-threatening colonic hemorrhage is a very rare condition in Crohn's disease. Lower gastrointestinal hemorrhage in Crohn's disease occurs in 0.6-2.5% of cases. In a patient presenting with severe gastrointestinal bleeding after ileocolectomy, mesenteric angiography provided precise localisation of the bleeding site in the area of the splenic flexure.
