Lack of inclusions

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.

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.

Inclusion Criteria:

• Age greater than or equal to 18 years
• Management by a general practitioner trained in 3-point venous ultrasound
• Suspicion of deep vein thrombosis by the general practitioner with prescription of a whole-leg Doppler ultrasound by a vascular physician. It is noted that the patient can be included from the moment the general practitioner had planned to refer the patient to the vascular physician for a suspicion of DVT, including in the absence of realization of DDimer on a low probability of DVT. It may also be included in case of positive DDimer tests.
• Signed written consent
• Patient covered by the French social security system

Exclusion Criteria:

• Whole leg ultrasound performed more than 72 hours after the initial examination
• History of homolateral deep vein thrombosis
• Patient objecting to the use of his data
• Refusal of written and signed consent
