Disclaimer
Status Of Recommendations Each pathway is designed to assist clinicians in situations when faced with a large array of possible diagnostic tests and examinations. However, it is recognised that diagnostic practice may differ from a particular pathway depending on local availability of equipment and expertise, as well as the experience of individual clinicians. Therefore each pathway is neither a rigid set of rules, nor a substitute for clinical assessment, and individual patient circumstances should always be considered.

Follow-up of Peripheral Stent
Ankle-brachial Indices
Usual first test, quick and cost effective to establish re-stenosis
- The risk of restenosis depends on multiple factors: drug eluting stents may reduce the risk of restenosis, infra-inguinal stents have an increased risk of restenosis; longer segments and complex disease also carry a higher risk
- Patient risk factors and co-morbidities should also be considered
- Not all restenosis is symptomatic
- There is no consensus on the optimal timing for monitoring patients after percutaneous therapy for peripheral vascular disease
- Early detection of restenosis is preferred as restenosis is easier to treat than complete occlusion
- The risk of restenosis is highest in the first 12 months, but can occur at any time
- Close follow-up is suggested in the first year, e.g. at 6 weeks, 3 months, 6 months and 12 months post-procedure, then annually thereafter
- Follow-up assessment should include taking a history to identify recurrent symptoms, physical examination and ABIs
- Duplex ultrasound is the preferred imaging modality for follow-up , though there have been no randomised trials performed
- Duplex ultrasound is reasonable for routine surveillance after endovascular procedures
- Although many clinicians add duplex ultrasound to routine surveillance, the Appropriate Use Criteria panel felt that surveillance more than annually was inappropriate or uncertain for asymptomatic patients
- Ongoing imaging is only indicated if further intervention is being considered; other co-morbidities and functional status should be taken into account
Duplex Colour Doppler Ultrasound
Duplex Colour Doppler Ultrasound
Recommended for routine surveillance and in the setting of recurrent symptoms following surgical or percutaneous intervention
- Lowest cost cross-sectional imaging modality
- Recommended imaging modality for routine surveillance and in the setting of recurrent symptoms following surgical or percutaneous intervention
- Able to localise lesion site and assess its haemodynamic significance
- Sensitive and specific for detecting in-stent stenosis by measuring peak systolic velocity (PSV) or velocity ratio (Vr)
- Limitation: Unable to provide information on loss of luminal volume or extent of stenosis (e.g. a focal stenosis compared to diffuse)
Catheter Angiography
Catheter Angiography
Gold standard for peripheral arterial imaging
- 'Gold standard' for peripheral arterial imaging
- Allows for intervention at the time of diagnosis
Non-invasive Angiography
Non-invasive Angiography
Includes Computed Tomography Angiography (CTA) and Magnetic Resonance Angiography (MRA) if no contraindications
- Advancing technology has increased the use of CT Angiography (CTA) and magnetic resonance angiography (MRA) for evaluating vascular disease, particularly prior to intervention
- When compared to catheter angiography, CTA provides better evaluation of all collateral vessels and surrounding tissues
- MRA may also have a role in pre procedural planning and for follow-up assessment after revascularisation
- MRA is more sensitive and specific than CTA or ultrasonography for detection of lower-limb PAD
