What is a Venous Doppler scan?
Deep Vein Thrombosis (DVT) occurs in approximately 2 million Americans each year. 600,000 of these patients develop pulmonary embolism and as many as 200,000 people die each year as a result of pulmonary embolism.
Venous Doppler studies use a technique called Doppler ultrasound to evaluate blood circulation in the veins of the arms or legs. A device called a transducer is passed lightly across different areas of your limbs, directing high-frequency sound waves (ultrasound) at superficial and deep veins. The sound waves are reflected back at frequencies that correspond to the velocity of blood flow, and are converted into audible sounds and graphic recordings.
