The first investigation of peripheral arterial disease is segmental arterial pressures, measuring the ankle/brachial pressure indices. This is combined with Doppler waveform analysis and Treadmill exercise testing.
Segmental arterial pressures combined with Doppler waveforms and treadmill exercise is the most accurate and cost effective method to screen for peripheral arterial occlusive disease.
If abnormal Doppler waveforms and ankle brachial pressure indices, pre or post exercise, are found in the patient, he/she will be given an appointment for further testing in the form of abdominal and peripheral arterial duplex scanning.
When referring a patient for peripheral arterial study, we will perform, segmental Doppler pressures, and will only proceed to abdominal and peripheral duplex scan if an abnormality is found.
