Chronic venous disease (CVD) is very prevalent and causes a significant financial burden in Western societies. Accurate diagnosis is mandatory to define the anatomy and pathophysiology involved in the disease process. Duplex ultrasound (DU) is a well-established non-invasive tool used for varicose veins work-up that, most recently, has also been utilized for follow-up after endovenous procedures such as endovenous laser or radiofrequency ablation and foam sclerotherapy. Insightful information on how DU is performed during varicose veins work-up and the rationale of DU utilization for endovenous procedures are discussed.
