[Effective physical method for the prevention of deep venous thrombosis of the leg].

A newly developed system for the physical prophylaxis of thromboses of deep veins of the leg is presented and its effect on various parameters is described. The invasive examinations were carried out in the blood of the femoral vein and artery on 48 patients (chronic cor pulmonale, varicosis, healthy persons) before and after a 24-hour external rhythmical (dynamic) compression of the feet and lower legs. In 9 out of 19 coagulation and blood gas analytical as well as haemodynamic parameters investigated ascertained changes with antithrombotic function could be proved. The effect depended upon the size and dynamics of the compression pressure as well as upon the size of the storage blood volume. An influence on the arterial circulatory crus was not observed. The present results confirm the up to now reported clinical success in the application of similarly effecting dynamic compression methods within the prophylaxis of thrombosis.
