IntroductionHaving in mind the rate of occurrence and clinical importance, venous thromboembolism implies venous thrombosis and pulmonary embolism as a result of embolisation of the thrombotic particles from deep veins or pelvic veins. Venous thrombosis of the deep veins may result in chronic vein insufficiency, but the primary medical problem is the possibility of development of pulmonary embolism which may cause permanent respiratory function damage or even fatal outcome.Venous Thromboembolism Prevention In StrokeThe high incidence of deep vein thrombosis (30% clinically and up to 50% subclinically) in acute stroke hemiparetic and bed ridden patients within two weeks from the onset and 1-2% pulmonary embolism with the fatal outcome in the first month clinically and 17% of all fatal outcomes in postmortem investigations present a necessity for the early venous thromboembolism prevention. On the other hand, the most powerful prevention strategy--anticoagulation has important limitations in acute stroke patients: almost impossible to be used in cerebral haemorrhage and a great risk for the development of haemorrhagic transformation in cerebral infarction. The fact that other prevention strategies have limited value requires an estimation of effectivity-risk ratio in venous thromboembolism prevention in stroke.ConclusionVenous thromboembolism prevention in stroke patients is necessary because of a greater risk for venous thromboembolism in these patients according to the nature of illness and functional disability, but also a problem because of limited possibility to recommend the proper medicament according to the risk of serious complications. The necessity of preventing venous thromboembolism and estimation of effectivity-risk ratio in stroke patients, beside plenty of studies and consensus conferences, remain individual and often very difficult.
