[Role of the musculovenous "pump" in draining the subcutaneous veins in varicose disease of the lower extremities].

The two-system phlebotonometry of lower extremities in 50 patients with varicose disease enabled the authors to make a conclusion about the great role of the duration of that phase of diastole when the blood runs from superficial veins into deep ones promoting the evacuation of the congested blood. This phase was found to be considerably shorter and even to disappear completely in patients at the decompensation stage. The drainage function of the musculo-venous "pump" is disturbed in patients with the varicose disease of the lower extremities and the degree of its insufficiency is in direct relation with the degree of the disease.
