What is Duplex Ultrasound for the Diagnosis of Acute and Chronic Venous Diseases about?

Venous diseases are highly prevalent medical conditions, mostly caused by valve incompetence (reflux) and/or obstruction of the vein lumen. Duplex ultrasound (DUS) is the first choice and, in many instances, the gold standard imaging technique for the diagnosis of reflux and obstruction. DUS is also used for obtaining venous access, guiding venous procedures, determining the immediate outcome of treatment, and short-term and long-term follow-up of patients. Cutoff value for venous reflux in the common femoral vein, femoral vein, and popliteal vein is greater than 1000 milliseconds; a lower cutoff (>500 milliseconds) is used in the superficial, perforating, and rest of the deep vein systems. Noncompressibility of the veins on axial axis, using grayscale technique, is the most sensitive and specific finding in acute deep vein thrombosis.
