Vascular Testing

ABI vascular testing, also known as ankle-brachial index testing, is a diagnostic test used to evaluate the circulation in the legs and feet. The test measures the blood pressure in the arms and ankles to determine if there is a narrowing or blockage in the arteries that supply blood to the legs and feet.

Here is an overview of what to expect during ABI vascular testing:

  • Preparation: Prior to the test, the patient will be asked to remove any tight clothing or jewelry around their arms and ankles.
  • Blood pressure measurement: The first step in ABI vascular testing is to measure the blood pressure in both arms using a high-tech wireless blood pressure cuff. It uses technology for pulse volume recordings and volume plethysmography.
  • Ankle blood pressure measurement: At the same time, the technician will measure the blood pressure in both ankles using a similar process. The high-tech wireless blood pressure cuff is placed around the ankle and is used to measure pulse volume recordings and volume plethysmography in the ankle arteries.
  • Calculation of ABI: The ankle-brachial index is calculated by dividing the ankle blood pressure by the higher of the two arm blood pressures. This provides a ratio that indicates the blood flow to the legs and feet.
  • Interpretation of results: The results of the test are interpreted based on the ABI ratio. A normal ABI is between 0.9 and 1.3, which indicates good blood flow to the legs and feet. An ABI of less than 0.9 suggests narrowing or blockage in the arteries that supply blood to the legs and feet, while an ABI of greater than 1.3 indicates stiff arteries.

ABI vascular testing is a non-invasive and relatively simple test that can provide important information about a patient’s vascular health. The test is commonly used to diagnose peripheral arterial disease (PAD), a condition in which the arteries in the legs and feet become narrowed or blocked due to the buildup of plaque. PAD can cause leg pain, cramping, and weakness, and may increase the risk of heart attack and stroke.

ABI vascular testing may also be used to monitor the effectiveness of treatments for PAD, such as lifestyle changes, medication, or surgical interventions. In some cases, ABI vascular testing may be used to screen for PAD in patients who are at increased risk due to age, smoking, diabetes, or other factors.

Overall, ABI vascular testing is a valuable tool in the diagnosis and treatment of peripheral arterial disease and other vascular conditions. The test is safe, painless, and non-invasive, and provides important information about a patient’s vascular health. If you are experiencing symptoms of PAD, such as leg pain or cramping, or if you are at increased risk due to other factors, talk to your podiatrist about ABI vascular testing.
