Teaching Points
- Intermittent claudication must be differentiated from lower extremity pain occurring as a result of non-vascular aetiologies
- Imaging studies are useful in defining the location and extent of vascular lesions before a percutaneous or surgical revascularisation procedure
- Doppler US, Magnetic Resonance Angioigram and Computed Tomography Angiogram are alternatives in the non-invasive investigation of peripheral vascular disease
- Angiography is useful prior to planned endovascular therapy or may be carried at the same time
