What is a bilateral venous ultrasound?
A venous ultrasound exam uses high-frequency sound waves to produce images of veins - the blood vessels that return blood to the heart.
Ultrasounds are non-invasive procedures that can be used to diagnose and treat a variety of conditions, such as blood clots, blockages, abnormalities in blood flow, or venous insufficiency.
Depending on the results of your venous ultrasound, your doctor may recommend an additional Doppler ultrasound. Doppler ultrasounds use changes in the frequencies of sound waves to measure the speed and direction of blood flow through blood vessels. Because ultrasounds can show images in real-time, Doppler ultrasounds have taken the place of X-ray angiography as the main method of measuring blood flow through the veins. Regular ultrasounds can show pictures of blood vessels and organs in the body, but cannot measure blood flow through veins.
