What is a Doppler Ultrasound Scan?

A Doppler Ultrasound Scan is a test that uses high frequency sound waves to image the blood flow through the major vessels in the body.  It allows assessment of the blood flow through the major veins and arteries, such as those in the legs, arms and neck. 

Abnormal blood flow, such as a narrowing or occlusion of the major vessels can be detected.  It is a simple, non invasive and painless procedure that does not involve any needles or being put in a tunnel.

Types of scans performed

  • Upper and lower limb veins for Deep Vein thrombosis (DVT)
  • Lower limb arteries for peripheral vascular disease
  • Upper limb arteries for occlusive disease and Thoracic Outlet syndrome (TOS)
  • Carotid arteries for suspected Transient Ischaemic Attack (TIA) or stroke
  • Fistula scans, fistula flow studies and vascular access
  • Varicose veins scans and pre surgery marking of veins
  • Graft surveillance post vascular surgery
  • Abdominal Aortic Aneurysm (AAA) surveillance
  • Endovascular Aneurysm Repair (EVAR) surveillance post AAA repair

DVT Clinic

This is a haematology run outpatient service for local GPs, unscheduled care and outpatient clinics in the Cardiff and Vale UHB area, who have patients that present with symptoms of a suspected lower limb DVT.

The clinician can phone and get an appointment for his patient either the same or next working day. The patient will be assessed by a DVT specialist nurse, a Doppler Scan performed and the patient treated if a DVT is found.

The service is based in Medical Physics and is open 8.30am to 4.30 pm, Monday to Friday. For enquiries phone 029 2184 8729.

What happens during the scan?

No special preparation is required for a Doppler Scan. The patient will be asked to lie on a couch and a small amount of gel applied to the skin of the area being examined. The Medical Physicist performing the scan will slide the handheld probe up and down the area being examined.

The probe sends images to the ultrasound monitor where they will be viewed and recorded by the physicist. After the scan is completed, the physicist will analyse the images and report the findings of the scan to the referring doctor.
