title: Evaluation of blood coagulation tests in deep venous thrombosis.
abstract: On the basis of the hemocoagulation and hemostasis parameters study the actual hemostasis state was evaluated in 30 patients treated for active deep venous thrombosis (DVT) in dependence on its extent. In comparison with 30 healthy persons there were found statistically significant changes in a majority of laboratory parameters that can indicate thrombophilic state. Platelet activation, increased coagulation system activity, decreased fibrinolytic activity as well as increased fibrinogen and fibrin degradation products were demonstrated. The positive correlation between the extent of DVT and the relevance of hemostasis changes was revealed which results to these conclusions: the more extensive DVT--the more intensive tendency to thrombophilia up to intravascular blood coagulation activation was observed. Although the adequate prolongation of the prothrombin time (during the coumarin therapy) or APTT (during the heparin therapy) was achieved, the laboratory parameters showed a therapy insufficiency. In the cases of laboratory signs of the activated intravascular blood coagulation we can recommended a fortification of the oral anticoagulant therapy by its combination with antiplatelet drugs or by its temporary replacement by the heparin therapy.
