The aorto-iliac segments need to be assessed with an abdominal scan when assessing the lower limb arteries for peripheral arterial insufficiency. Doppler waveform analysis of the common femoral artery alone can lead to eroneous information as the common femoral waveforms can become normal even with moderate proximal aortoiliac occlusive disease.
Advances in ultrasound techniques in recent years have simplified the study of the abdominal vasculature. We routinely include both the aortoiliac and peripheral arteries when scanning the patient with peripheral arterial disease.
Indications:
- Intermittent Claudication
- Undiagnosed leg pain
- Leg ulcers
- Surveillance after peripheral arterial procedures
- Aneurysm
