What is ABI (Ankle-Brachial Index)?
ABI, also called Ankle-Brachial Index test, is a test which compares the blood pressure in your ankles to the blood pressures in your arms. It is a safe and painless test that helps your physician determine if your legs are getting the proper amount of blood supply
What is PVR (Pulse-Volume Recording)?
A PVR study is a noninvasive vascular test in which blood pressure cuffs and a hand-held ultrasound device (called a Doppler or transducer) are used to obtain information about arterial blood flow in the arms and legs. Noninvasive means the procedure does not require the use of needles, dyes, radiation or anesthesia. The blood pressure cuffs and Doppler are used to determine the presence, severity and general location of peripheral arterial occlusive disease.
Exercise Testing PVR
During the exercise testing PVR, the patient walks on a treadmill to try to reproduce the symptoms he or she has experienced. Then, the blood pressure cuffs are placed on the patient’s arms, legs, thighs, ankles, calves and feet. The blood pressures are measured again to determine the location of the potential blockage or narrowed area.
