A leg arteries full-assessment ultrasound is an examination to assess the blood flow of the legs and feet and is done in two parts. Ankle Pressures (blood pressures) taken at rest and, if possible, during exercise and colour duplex ultrasound.
This examination evaluates accurately the blood flow in and to your legs and feet. It is usually performed to help your doctor manage a condition you may have such as; painful feet, ulcers on your legs, pain/tightness in the leg or calf muscle or follow-up after surgery on your leg. For more information please see our patient information brochure for this examination. As there are a range of reasons why you are having this test, it is best discussed with your doctor.
- 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.
