ABI Test with PVR

An ABI test or Ankle-Brachial Index test is done by measuring the blood pressure of an individual at the ankle and in the arm while the patient is at rest. Some patients are also asked to do a stress test where the pressure measurements are taken at both sites after using a treadmill. This test is done to ensure that a patient doesn’t have peripheral arterial disease of the legs. For patients that already have peripheral arterial disease of the legs, this test is used to gauge the effectiveness of the treatment.

  1. Blood pressure cuffs are placed on arm and leg
  2. Cuffs are then inflated
  3. Doppler is used to listen to the blood flow in leg and arm
  4. Results are compared.

Normally, the blood pressures should be about equal, but if your ankle blood pressure is less than half your arm pressure, this could be an indication that you have narrowed leg arteries.

PVR, also called Pulsed Volume Recording is a test which compares the blood pressure in your legs to the blood pressure in your arms. The test is done to determine if there is adequate blood supply to your legs and determine if there may be a narrowing of the vessel that carries blood to your legs.
