Compression Ultrasonography in Non-high Probability of Deep Vein Thrombosis
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
University Hospital, Strasbourg, France
700 participants
Feb 21, 2022
INTERVENTIONAL
Conditions
Summary
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.
Eligibility
Inclusion Criteria5
- adult patient

- Subject able to understand the objectives and risks of the research and to give a signed and dated informed consent
Exclusion Criteria6

- Patient with a high probability of DVT
- Impossible to perform a whole leg doppler ultrasound within 5 days
- Pregnant or breast-feeding woman, on patient's declaration
