Ankle Brachial Indicies (ABI)
- Coronary artery disease (CAD)
- Smoking and hypertension
- No previous history of peripheral vascular disease (PVD) or vascular surgery
The procedure will take 20 minutes to complete. Written results will be given to patient's primary physician, who will be phoned immediately if abnormalities are identified. The procedure will be preformed by a registered vascular technologist (RVT) and formally read by a cardiovascular physician.
- An explanation of the procedure will be given to patient in a private, comfortable room
- A short medical history and blood pressure will be obtained
- The patient will lie down on an exam cart for the test
- Cuffs are placed around each ankle and each upper arm
- An ultrasound pencil probe and ultrasound gel are used to obtain a Doppler signal
- Brachial systolic pressures will be taken at both upper arms. Systolic pressures will be obtained using both the dorsalis pedis artery (DPA) and the posterior tibial artery (PTA). The higher of the two pressures will be divided by the higher of the two brachial pressures to obtain an index.
- No further testing is recommended if results are normal
- Complete formal pulse volume recording (PVR) will be recommended if results are abnormal
