title: [Determination of venous capacity and flow by plethysmography with occlusion of the veins].
abstract: These examinations are based on the knowledge that mercury-in-rubber strain gauge method for venous occlusion plethysmography is suitable for measuring the venous capacity and venous return. This research reports on the value of this method in diagnostics. The results are as follows: the venous capacity decreases markedly in the group of patients with deep vein occlusions of the legs. However, it is not possible, basing on the measurements, to differentiate between occlusions above and those below the knee. The same applies to multiple occlusions in the same vein meaning that venous occlusions in the deep veins of the lower limb cannot be examined separately. The results of a single patient are mostly but not always similar to those of this corresponding group. Therefore venous occlusion plethysmography does not have the same diagnostic value as phlebography in deep vein occlusions for the individual patient.
