Compression Ultrasonography in Non-high Probability of Deep Vein Thrombosis

Recruiting now · Not applicable

Conditions studied: Deep Vein Thrombosis

In brief

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.
