![]() The scan usually takes between 15 and 30 minutes to complete. The Vascular Scientist will need to press quite hard on the leg at intervals and will also need to squeeze the leg, this helps to see the blood flow in the veins. Some ultrasound gel will be placed on your leg. Occasionally the scan will be done with you standing. Usually the couch will then be tilted so you are in a semi standing position. You will be asked to lie down on a couch. What does the test involve?Ī Vascular Scientist will perform and report the scan. It will therefore be necessary to remove trousers or tights, although a loose skirt can just be pulled up out of the way. Occasionally it may be necessary to scan the veins in the tummy as well. The scan will start at the groin level of the leg to be examined and extend to ankle level. You may however wish to consider the clothes that you will be comfortable in when having the scan done. There is no specific preparation for this test. Doppler is a form of ultrasound scan in which blood flow is detected during a Doppler ultrasound scan you will frequently hear your pulse. It does not use any form of radiation and is considered completely safe. It is most commonly known as the type of scan used to look at unborn babies. Ultrasound scans use very high frequency sound waves to build up pictures of inside the body. What is an Ultrasound scan or Doppler Scan? Occasionally the veins can become blocked (thrombosis).Īn ultrasound scan identifies which veins are not working properly and this helps your Doctor decide on the best form of treatment for you. Unfortunately these valves can stop working properly, causing varicose veins, swelling and discomfort. Both have valves in them that should allow the blood only to go back towards the heart. There are two systems of veins in both legs, the superficial veins and the deep veins. The veins in the legs return the blood from the legs to the heart. ![]() PDF: Ultrasound scan of the viens in the legs final 175KB People with hard-to-control or long-standing diabetes or significantly blocked arteries might need to have a blood pressure reading at the big toe (toe-brachial index) to get an accurate test result.Ref: B-435/AE/Vascular/Ultrasound scan of the veins in the legs You might have more testing, such as ultrasound or angiography, to view the arteries in your legs. An ankle-brachial index number in this range indicates a diagnosis of PAD. You might have an exercise ankle-brachial index test. An ankle-brachial index number in this range indicates borderline PAD. But if you have symptoms of PAD, you might have an exercise ankle-brachial index test. An ankle-brachial index number in this range suggests that you probably don't have PAD. The index is a ratio of the two measurements.īased on the number calculated, your ankle-brachial index may show you have: The blood pressure measurements from the arms and ankles are used to determine the ankle-brachial index. Your health care provider will discuss your test result with you. No special precautions are needed afterward. The ankle-brachial index test should take only a few minutes. The device uses sound waves to produce images and allows the pulse in the ankle arteries to be heard after the cuff is deflated. This is done using an inflatable cuff and a hand-held ultrasound device that's pressed on the skin. ![]() A care provider measures your blood pressure in both arms and both ankles. Typically, you lie on a table on your back. You likely will be asked to rest for 5 to 30 minutes before the test. This allows the provider doing the ankle-brachial index test to easily place a blood pressure cuff on an ankle and upper arm. The test is painless and similar to having blood pressure taken in a routine medical visit. No special preparations are needed for an ankle-brachial index test. Severe leg pain might require a different imaging test of the arteries in the legs. But this discomfort is temporary and should stop when the air is released from the cuff. The blood pressure cuffs might cause pain on the arm and leg while they inflate.
