Upper Limb Duplex Ultrasound

An ultrasound scan may be necessary for your upper limbs. In this vascular laboratory we regularly assess for:

  • venous and arterial assessment prior to arterio-venous fistulae for dialysis
  • presence of deep or superficial thrombosis
  • presence of arterial insufficiency
  • review of arterio-venous fistulae for ongoing dialysis

This ultrasound is similar to the carotid arterial ultrasound. You will either be lying down or sitting up with your shirt removed enough to access the arm (from the shoulder down to the hand). You will be asked to remove any jewellery and/or watch. The sonographer will place gel on the examination region of the arm and place a probe (also known as a transducer) on the skin and image your vessels. The scan is non-invasive and painless. The test duration is 30 minutes.
