[Functional disorders of the venous muscular pump seen in chronic venous insufficiency].

The study of the functioning of the venous muscle pump by means of plethysmographic tests allowed us to discover a clearly marked condition in the varicose veins combined with chronic venous deficiency and in the thromboses of the deep veins. In the case of varicose veins, we found an interdependence between the gravity of the functional lesions and the existence of insufficient perforating veins. The study, which dealt with cases of thrombosis, showed that the trophic skin lesions appear only after several years of poor nervous pump functioning.
