Venous thrombosis in a child with ulcerative colitis in remission : a case report

Over the past 70 years, an association between venous thrombo- embolism and inflammatory bowel disease has been described. We report on a thirteen year old boy with ulcerative colitis and venous thrombosis. Literature on incidence of venous thromboembolism in inflammatory bowel disease (IBD) is reviewed as well as the possible pathogenetic mechanisms of this 'hypercoagulable state' : role of acquired risk factors, inflammation, coagulation abnormali- ties and platelets. Finally, treatment of IBD and thrombosis is discussed. (Acta gastroenterol. belg., 2014, 77, 71-74).
