You might want to wear loose, comfortable clothing that allows the technician performing your ankle-brachial index test to easily place a blood pressure cuff on your ankle and upper arm. Results Your doctor uses the blood pressure measurements from your arms and ankles to calculate your ankle-brachial index. It is a test that your doctor can order if they are concerned you may have symptoms of peripheral artery disease, or that you may be at risk for this condition. Your doctor will discuss your test result with you. This test can be very useful as one component of making a diagnosis of a condition like peripheral artery disease.

How you prepare No special preparations are needed for an ankle-brachial index test. The disease occurs when narrowed arteries reduce the blood flow to your limbs. The process is very similar to the one performed on your arms. A technician will take your blood pressure in both arms and in both ankles, using an inflatable cuff and a handheld ultrasound device to hear your pulse. The technician will start by putting a blood pressure cuff on one arm, usually the right arm. Measured by the Doppler wand, the inflation continues until the pulse in the artery ceases. Typically, you lie on a table on your back, and a technician measures your blood pressure in both arms and both ankles, using an inflatable cuff and a hand-held ultrasound device that's pressed on your skin.

The device uses sound waves to produce images and allows your pulse to be heard in your ankle arteries after the cuff is deflated. A low ankle-brachial index number can indicate narrowing or blockage of the arteries in your legs. This can help ensure that you get the most appropriate treatment right away. You don't need to follow any special precautions afterward. Hiatt, Björn Jönsson, Philippe Lacroix, Benôıt Marin, Mary M.

But this discomfort is temporary and should stop when the air is released from the cuff. The blood pressure cuff is then slowly deflated. After the procedure The ankle-brachial index test should take only a few minutes. You may have ankle-brachial index testing before and immediately after walking on a treadmill. . This process is then repeated on your left arm.

After the technician has completed all the measurements, those numbers will be used to calculate the ankle brachial index for each leg. The ankle-brachial index test compares the blood pressure measured at your ankle with the blood pressure measured at your arm. You will remain in the same reclined position. Your doctor might recommend an exercise ankle-brachial index test. The measurements can highlight any potential problems, like blockages or partial blockages in blood flow to your extremities. As the blood pressure cuff inflates and then deflates, the tech will use the ultrasound device or Doppler probe to listen for your pulse and record the measurement. They will then rub a little gel on your arm right above your brachial pulse, which is just above the inside crease of your elbow.

It thus has potential for screening for , although no evidence-based recommendations can be made about screening in low-risk patients because clinical trials are lacking. If you have severe leg pain, your doctor may recommend a different imaging test of the arteries in your legs. An ankle brachial index test is a quick way for your doctor to check the blood flow to your extremities. The test is painless and similar to getting your blood pressure taken in a routine visit to your doctor. The process will then be repeated on the other ankle.

The tech will inflate and deflate a blood pressure cuff around one ankle while using the ultrasound device to listen for your pulse in the arteries that supply blood to your foot. A blood flow detector, commonly called Doppler wand or Doppler probe, and a blood pressure cuff are usually needed. If you have severe diabetes or significantly blocked arteries, your doctor may need to read your blood pressure at your big toe toe-brachial index to get an accurate test result. When the artery's pulse is re-detected through the Doppler probe the pressure in the cuff at that moment indicates the systolic pressure of that artery. The ultrasound waveform of the artery helps differentiate between these possibilities. You lie down for a few minutes before the test begins.
