[Venous thrombosis at the beginning of the new millennium].

The author presents new theories related to the etiopathogenesis, diagnostic procedures and therapy of the deep vein thrombosis, according to latest publication data. Dilemmas related to the diagnosis and therapeutic strategies in hospital as well as the possibilities of treatment on the outpatient basis will be discussed. The intention was to cut the costs of therapy in favour of low molecular weight heparin treatment on the outpatient basis, as the cornerstone of the new therapeutic possibilities besides the importance of fibrinolytic therapy. Hereditary and acquired thrombophilia and venous thrombosis related to pregnancy will be discussed.
