Official title
Evaluation of the Predictive Value of Compression Venous Ultrasound by the Emergency Physician for Excluding the Diagnosis of Proximal Deep Vein Thrombosis (DVT) in Patients With Non-high Clinical Pretest Probability
Overview
Compression ultrasound is commonly used in emergency department. Accuracy to rule out deep vein thrombosis is excellent but lower then Ddimer assessment which is actually gold standard. With progress in formation of emergency physicians (EP), quality of material used, the investigators hypothesize that compression ultrasound can rule out deep vein thrombosis in case of non high probability, as standard care and DDimer assay.
Interventions
- Other compression ultrasound
performing a compression ultrasound
Primary outcome measures
- Negative predictive value of compression ultrasound for diagnosis of deep vein thrombosis [Time frame: The measurement is assessed during ED stay or in 5 days if DD is positive with no DVT in compression ultrasound]
Eligibility criteria
Inclusion criteria

- Subject with a social health insurance plan
- Subject able to understand the objectives and risks of the research and to give a signed and dated informed consent
Exclusion criteria
