A vein or venous ultrasound provides images of the veins throughout the body. The most common reason for an ultrasound is to search for blood clots, especially in the veins of the leg. This condition is often referred to as 'Deep Vein Thrombosis' or 'DVT'.
These blood clots can break off and pass into the lungs, where they can cause a dangerous condition called 'pulmonary embolism'. However, if the blood clot in the leg is found early enough, treatment can be started to prevent pulmonary embolisms.
A vein ultrasound study is also performed to determine the cause of leg swelling and leg pain. In people with varicose veins, the valves that keep blood flowing back to the heart in the right direction may be damaged, and a venous ultrasound can help the specialist decide how best to deal with this condition.
Test results are sent to your doctor for evaluation. Your doctor will share the results with you.
