Some problems in the practical use of the functional segmental plethysmography, previously devised by us as a new functional test of veins of the lower extremities, were dissolved and, simultaneously, the exactness of the measurement was enhanced by the conversion of the detector from the air cuff to the mercurj' strain gauge. By measurements of 20 healthy limbs, normal values of venous functions of the lower extremities were corrected. From the results of clinical application, the phatophysiological changes of various venous diseases of lower extremities were discussed. The main functional change of the venous system is the venous reflux in cases of primary varicose veins and the venous obstruction in cases of phlebothrombosis. Meanwhile, in cases of postthrombotic syndrome, venous obstruction and reflux coexist. The role and usefulness of this examination in this aspect of clinical application were emphasized.
