[Considerations on the role of the so-called non-invasive investigations: Doppler effect, rheography and labeled fibrinogen testi in acute arterial and venous leg].

The author outlines the first results obtained with Doppler investigation in arterial and venous emergencies. He analyzed thereafter the Kakkar test, through which he can detect acute venous more easily than with Doppler. He insists on the difficulty of detecting through either one of these methods, some cases of thrombosis located in the abdominal veins.
