Peripheral Arterial Disease Screening (PAD)

The circulation to the lower extremities comes from the lower part of the aorta (the largest blood vessel in the body). Certain conditions, including smoking, hypertension (high blood pressure), high cholesterol and diabetes can cause a narrowing of this part of the aorta or its branches. Often, this will produce a burning in the calf muscles with walking which goes away immediately when walking ceases. A very simple screening test called an ankle-brachial index (ABI) can screen for this problem. This is a noninvasive, rapid test performed in the office.
