The Procedure

  • The examination is done in two parts – Ankle pressures study and Colour duplex ultrasound.
  • You will be taken to a private room. A staff member will explain the procedure and answer any questions you may have.
  • You will be asked to remove outer clothing from your lower body.
  • Gel is placed on the area of interest so that flow waveforms can pass through to the relevant vessels. This is done in several areas on your legs.
  • Then you may be required to walk on a treadmill for 5 minutes and your symptoms recorded.
  • More flow waveforms are recorded after the exercise.
  • You will then lie down on the examination table to have the colour duplex ultrasound. Gel will be placed on the skin so that the sound waves can pass through to the relevant vessels. This will be from the abdomen down to the ankles.
  • The Ankle pressure study takes approximately 30 minutes.  The Colour Duplex ultrasound takes approximately one hour.
