[Venous capacity and drainage volumes of arm veins].

On 29 test persons after clinical angiological and cw-Doppler-sonographic exclusion of an obstruction of the deep veins and an arterial occlusive disease on the upper extremities the capacity of the veins and the drainage volume were determined by means of the venous-occlusion plethysmography. The angiological measuring places Compactus 540 and Periquant 3800, respectively, of the firm Gutmann (group 1) and the 2-channel occlusion plethysmography of the former nationally owned measuring device factory Ballenstedt (VEB Messgerätewerk Ballenstedt) (group 2) were at our disposal. Apart from the obsolute values of the capacity of the veins and of drainage volume on account of the large interindividual dispersions the quotients were determined in the comparison of sides. In the two groups the drainage volume showed significantly larger values on the right arm than on the left one. In group 2 the measuring of the capacity of the veins and the drainage volume resulted in essentially larger values than in group 1. In contrast to the absolute values the quotients of the measuring values did not show any significant differences between the two groups so that it seems that these are better suitable of the judgment of the venous obstruction behaviour.
