American College of Cardiology/American Heart Association (ACC/AHA) 2005 | Rest supine for 10 minutes | Handheld Doppler ultrasound device & sphygmomanometer | 2 | Handheld Doppler ultrasound device & sphygmomanometer | Dorsalis Pedis artery and Posterior Tibial artery. | Higher ankle systolic pressure (for that leg) divided by higher brachial pressure of the two arms. |
Scottish Intercollegiate Guidelines Network (SIGN) 2006 | Not mentioned | Handheld Doppler ultrasound device & sphygmomanometer | 2 | Handheld Doppler ultrasound device & sphygmomanometer | Dorsalis Pedis artery/ Anterior Tibial artery & Posterior Tibial artery. If these cannot be located, assess the Peroneal Artery | Higher ankle systolic pressure (for that leg) divided by higher brachial pressure of the two arms. |
Trans-Atlantic Intersociety Consensus (TASC) 2007 | Not mentioned | Doppler Instrument & sphygmomanometer | 2 | Doppler Instrument & sphygmomanometer | Dorsalis Pedis artery & Posterior Tibial artery. | Divide both ankle pressures by higher brachial pressures. |
Society for Vascular Technology of Great Britain and Ireland (SVT) 2010 | Rest supine for 5-10 minutes prior to procedure | Handheld continuous wave Doppler ultrasound device & sphygmomanometer | 2 | Handheld continuous wave Doppler ultrasound device & sphygmomanometer | Dorsalis Pedis artery & Posterior Tibial artery. | Higher ankle systolic pressure (for that leg) divided by higher brachial pressure of the two arms. |
European Society of Cardiology (ESC) 2011 | Not mentioned | Handheld Doppler ultrasound device & sphygmomanometer | 2 | Handheld Doppler ultrasound device & sphygmomanometer | Posterior Tibial artery & Anterior Tibial artery. | Higher ankle systolic pressure (for that leg) divided by higher brachial pressure of the two arms. |
National Institute for Clinical Excellence (NICE) 2012 | Rest supine when possible. Rest period should be “long enough for blood pressure to return to normal” | Handheld Doppler ultrasound device & sphygmomanometer | 2 | Handheld Doppler ultrasound device & sphygmomanometer | Three arteries, one of which must be the Peroneal artery as this “may be the only one present in some people, particularly those with diabetes”. | Higher ankle systolic pressure (for that leg) divided by higher brachial pressure of the two arms. |
American Heart Association (AHA)–scientific statement 2012 | Rest 5-10 minutes in supine position | Handheld Doppler ultrasound device & sphygmomanometer | 2 | Handheld Doppler ultrasound device & sphygmomanometer | Dorsalis Pedis artery & Posterior Tibial artery. | Higher ankle systolic pressure (for that leg) divided by higher brachial pressure of the two arms. |
