The ankle-brachial index, or ABI, is a measurement of blood flow in your leg arteries.
Hardening of the arteries can cause a narrowing or blockage of the leg arteries. This is also known as peripheral arterial disease (PAD).
PAD affects between 8 and 12 million Americans. Symptoms of PAD may include a discomfort in muscles of the calves, thighs or buttocks that comes on with walking (claudication) and goes away after a few minutes of rest.
More severe cases of poor circulation may even lead to amputation (removal of a leg or foot) and death because of the lack of circulation through the legs.
Sometimes, PAD can decrease leg blood flow without causing any symptoms at all. The ABI is the safest and most reliable test to find PAD.
The entire ankle-brachial index (ABI) procedure takes about 20 to 30 minutes.
Your primary health care provider will give you the results of your test.
The ankle-brachial index (ABI) will only help your health care provider confirm peripheral arterial disease (PAD). It does not cure your circulation problems. The test results give your health care provider information about the flow of blood through your arteries.Together you and your health care provider can decide how to improve your circulation problems.
If you have decreased blood flow through your arteries, your health care provider can suggest things you can do to improve your circulation, such as quitting smoking or increasing your exercise. You may need to have anon-surgical or surgical procedure to improve your circulation.Your health care provider will give you with more information about your condition and discuss your options for treatment.
