Peripheral arterial disease

ADULT

If any of the following are present or suspected, please refer the patient to the emergency department (via ambulance if necessary) or seek emergent medical advice if in a remote region.


  • Crescendo or multiple recent TIA (Transient Ischemic Attack) / amaurosis fugax
  • Acute stroke
  • Acute aortic dissection
  • Ruptured AAA
  • Symptomatic AAA (abdominal/back pain/tenderness, compressive symptoms, distal embolisation)
  • Axillary vein thrombosis, iliofemoral DVT
  • Acute DVT
  • Active infection in leg with peripheral arterial disease
  • Diabetic foot infection (refer to high-risk foot pathway)
  • Acute arterial ischemia/threatened limb
  • Ischaemic changes and/or threatened limb (ulcer, gangrene, rest pain)
  • Active infection in leg with peripheral arterial disease
  • Diabetic foot infection (refer to high-risk foot Healthpathway)
  • Foot ulcer with infection and systemically unwell or febrile, invasive infection or rapidly spreading cellulitis (defined by peripheral redness around the wound >2cm), acute ischaemia, wet gangrene, acute or suspected Charcot - A
  • Thrombosed AVF (refer to vascular registrar on call or the renal access nurse)

  • Refer to HealthPathways or local guidelines
  • Advance health directive (where available)
  • Diabetic foot ulcer: High-risk foot clinic (referral via podiatry and access via telehealth available –  Statewide Diabetes Clinical Network will provide details)
  • Asymptomatic peripheral arterial disease especially tibial artery stenosis or occlusion when the foot is healthy and the symptoms are proximal to the lesions in non-diabetic patients, do not warrant referral and can be managed conservatively with risk factor modification and exercise therapy.  Other causes for the more proximal leg pain should be sought.
  • Atherosclerosis risk factor management (antihypertensive; diabetes, dyslipidaemia)
  • Lifestyle modification (Increased activity, dietary, weight, smoking, alcohol)
  • Claudication with no impact on quality of life should be managed conservatively with risk factor control, graduate exercise therapy and anti-platelets

    • Intermittent claudication with no signs of limb-threatening ischaemia >50m
