[Compression therapy in deep venous thrombosis].
External compression, both intermittent by pneumatic pumps and continuous by anelastic or elastic bandages and by graduate compression stockings, play a pivotal role in prophylaxis of Deep Venous Thrombosis (DVT). The use of external compression in DVT therapy and in prophylaxis of pulmonary embolism (PE) and of post-thrombotic syndrome has not been validated as well as in DVT prophylaxis. The pathophysiologic properties of the external compression and the most recent evidences about the early mobilization of the patients with DVT and about Low Molecular Weight Heparin (LMWH) therapy suggest the advantages of the external compression. The authors review the most important clinical investigations about early use of external compression in DVT joined with pharmacological therapy: the results have been the reduction of the growth of the thrombus, the reduction of PE ratio, the prevention of the post-thrombotic syndrome, the indirect improvement of the quality of life. Finally the authors confirm the recommendations about the use of physical therapy with early mobilization and external compression joined with LMWH anticoagulation in DVT.
