USG Scan - Lower Limb Doppler Test

What is USG Scan - Lower Limb Doppler Test?

A Doppler ultrasound is a risk-free and pain-free procedure that uses high-frequency sound waves to measure the amount of blood flow through your arteries and veins, usually those that supply blood to your arms and legs. Vascular flow studies detect the abnormal flow within an artery or blood vessel. It helps to diagnose and treat a variety of conditions, including blood clots and poor circulation. A Doppler ultrasound can be used as part of a blood flow study. It can also reveal blocked or reduced blood flow through narrowed areas in the arteries, which could eventually lead to a stroke.

Preparation for USG Scan - Lower Limb Doppler Test

In general, there’s no preparation required for this test. If you’re a smoker, your doctor may ask you to stop smoking for several hours before the test. Smoking causes your blood vessels to narrow, which can affect the results of your test. A Doppler ultrasound is a noninvasive, painless procedure that doesn’t expose you to harmful radiation. There are no risks associated with this test, and most people feel little to no discomfort during the procedure.

Uses of USG Scan - Lower Limb Doppler Test

Doppler ultrasound is done in case if arteries and veins of legs show signs of decreased blood flow. It is done to cure: Deep vein thrombosis (DVT), a condition that occurs when a blood clot forms in a vein deep inside your body. Superficial thrombophlebitis, an inflammation of the veins due to a blood clot in a vein just below the skin's surface. Arteriosclerosis, a narrowing and hardening of the arteries that supply blood to the legs and feet. Thromboangiitis obliterans, a rare disease in which the blood vessels of the hands and feet become inflamed and swollen. Vascular tumors in your arms or legs. A Doppler ultrasound can help determine the blood pressure within your arteries. It can also show how much blood is currently flowing through your arteries and veins.

Procedure for USG Scan - Lower Limb Doppler Test

The procedure can vary slightly, but in general, you can expect the following: You’ll be asked lay down on bed after wearing a hospital gown and remove clothing, jewelry, and any other objects from the leg area as it will be studied. Doctor will then place a water-soluble gel on a handheld device called a transducer, which directs high-frequency sound waves into the arteries or veins being studied. To examine your arteries, blood pressure cuffs will be placed around the thigh or ankle to compare the blood pressure in different parts of your legs. As the transducer is pressed against your skin and moved along your leg, it starts generating images. The transducer sends sound waves through your skin to the blood vessels. With the received sound waves echo of blood vessels, computer will produce graphs to determine the flow. As transducer will be moved to different areas, you may hear a 'whooshing' sound of blood flow. When examining, doctor will look for narrowing of the blood vessels which may cause skin discoloration, pain when you walk or rest, and ulcers on the foot or ankle.
