Lower Limb Arterial Duplex Ultrasound

An arterial duplex ultrasound is similar to the carotid ultrasound and is utilized to examine the circulation in the major blood vessels of the body. A map of the arteries in your abdomen and legs is detected by the sonographer to aid in the investigation of:

  • Leg pain when walking
  • Resting leg pain
  • Foot, ankle, heel or toe ulcers
  • Skin discolouration
  • Aneurysm
  • The results of balloon angioplasty, stenting or bypass operations.

The procedure is performed lying on the examination couch on your back.

The sonographer will apply warm gel to your abdomen and legs. You will be scanned from the level below your heart to your feet which will take about 30-60 minutes to complete.

A 6-8 hour fast may be required depending on the area to be assessed, clerical staff will advise you at the time of booking. Intestinal gas in the abdomen after eating is one of the major obstacles the sonographers face when performing this exam.

We ask you to refrain from smoking and chewing gum or mints before the examination to facilitate better visualisation.

Diabetics should make the clerical staff aware of their condition at the time of booking, as staff will endeavour to make the appointment early in the morning, if this is possible.

All patients should take their usual oral medications with a small amount of water.
Leave jewellery at home and wear loose, comfortable clothing. You may be asked to change into a gown.
