[Value of rheoplethysmography with venous occlusion in the detection of venous thrombosis]. / Valeur de la rhéopléthysmographie avec occlusion veineuse dans la détection des thromboses veineuses.

The study of the correlations between occlusive rheoplethysmography (RPO) and phlebography, carried out in 170 explorations, shows an over-all rate of 78.3% correct correlations. This correlations is more accurate for negative RPOs (91.8%) than for positive ones (59.6%). There are in fact few inaccurate negatives (i.e. venous thrombosis with negative RPO) but there are a certain number of erroneous positives, linked basically with states of cardiac insufficiency and phlebitic after-effects. The RPO examination is a useful complement to the clinical data; it means that the number of necessary phlebographical examinations can be cut down, and it provides a useful guide to treatment options.
