Venous Duplex

A venous duplex (venous ultrasound) utilizes harmless sound waves to detect blood clots in the veins of the arms or legs of the patient. The sound waves leave the transducer, bounce back to the transducer, and are converted to images on a screen that may be recorded on paper or on a video. A transducer is placed on the skin and follows the vein, imaging it by sound waves or ultrasound. These images may demonstrate the presence of a thrombus or a clot in the leg or arm. The nurse may also obtain a Doppler image by bouncing sound waves off the blood vessel to obtain blood flow patterns.

There is no preparation for a venous ultrasound or venous duplex. One hour should be allowed for this test. A physician will read the test.
