A venous Doppler is a specialized ultrasound procedure that evaluates the veins throughout the body in order to determine the cause of varicose veins, as well as plan out treatment of affected veins and identify blood clots, vessel narrowing, tumors and other abnormalities within the veins. Doppler technology allows the movement of blood through the veins to be viewed as well.
During the venous Doppler procedure, a clear gel is applied to the skin of the targeted area, and a transducer is moved back and forth against the skin to produce images of the internal venous structures. This procedure is painless and takes less than 30 minutes to perform. Venous ultrasound is highly effective in identifying blood clots before they lead to serious complications, and also produces clearer images than other imaging procedures.
