[Comparison of plethysmography findings before and following varicose vein surgery]

In the chronic venous insufficiency on the basis of a primary varicosis the occlusion plethysmography of the veins is a suitable remedy in the positioning trial before and after a combined phlebectomy to determine the capacity of the venous part of the circulation on the lower extremity. In altogether 160 patients the functional capacity of the venous valves with the initial inclination to swelling St as well as the capacity of the venous vascular system on the calf and the ankle were established by the determination of the maximal venous capacity Vmax. It could be proved that particularly in stage III of the chronic venous insufficiency the haemodynamically most effective efficacy can be achieved by an operation of the varices.
