title: [Treatment of venous thromboembolism].
abstract: The main objectives in the treatment of venous thromboembolism are to prevent clot extension and pulmonary embolism, to reduce mortality and to prevent recurrent thromboembolic events as well as postthrombotic disorders. Initial and effective anticoagulation with heparin, preferably with low molecular weight heparin (LMWH), or with fondaparinux is the most important measure. Unfractioned heparin (UFH) is as effective as LMWH, but requires coagulation-monitoring and is associated with a higher risk of heparin-induced thrombocytopenia. In patients with renal insufficiency direct determination of anti-factor Xa activity and dose adjustment is recommended, since drug accumulation can occur over time. In those patients UFH instead of LMWH might be favored. Long-term treatment should be administered with vitamin K-antagonists (INR-target range 2-3) for a duration of 3 to 6 months. In case of recurrent venous thromboembolism, indefinite therapy is recommended. Additional treatment with compression stockings is reasonable. Patients who do not require hospital treatment for other conditions, who have a low bleeding risk, no excessive venous congestion and no symptomatic pulmonary embolism can safely be treated at home. In most cases bed rest is not necessary. Thrombolysis or surgical thrombectomy is seldomly indicated in severe thromboembolism.
