title: [Thrombosis in inflammatory bowel disease: mechanisms and risk factors].
abstract: BACKGROUND
  Thromboembolic manifestations are frequent in patients with inflammatory bowel disease.
  
  
  OBJECTIVE
  To explaim the mechanisms of thromboembolic manifestations in inflammatory bowel disease.
  
  
  METHODS
  Literature review.
  
  
  RESULTS
  Risk factors of thrombosis in inflammatory bowel disease are acquired or genetic. The most important factors are thrombocytosis, increased of activation of platelets and hyperhomocysteinemia. Other factors such factor V leiden, antithrombin III and antiphospholipid antibodies are observed in inflammatory bowel disease patients but not always correlated with thromboembolic manifestations.
  
  
  CONCLUSIONS
  The mechanisms of thrombosis in inflammatory bowel disease are complex are intricate.
