Details and patient eligibility

About

The objective of this study is to evaluate the diagnostic efficiency of general practitioners for the diagnosis of proximal deep vein thrombosis of the lower limbs compared with whole-leg ultrasound with Doppler performed by the vascular physician.

Full description

After being informed about the study and the potential risks, all patients who have given their written consent and who meet the eligibility criteria will benefit from a 3-point compression ultrasound performed by the general practitioner before being referred for a whole-leg ultrasound with Doppler at the vascular physician.

It may also be included in case of positive DDimer tests.
