Effect of intermittent compression of the arms on deep venous thrombosis in the legs

Despite the presence of venostasis in the legs, intermittent compression of the arms during and after surgery reduced the incidence of deep venous thrombosis (D.V.T.) in the legs to half that in control patients and maintained blood fibrinolytic activity at preoperative values. It is suggested that the release of fibrinolytic activators is essential to the prophylactic action of pneumatic leggings.
