Duplex Ultrasound Scan
What is a Duplex Ultrasound scan?
A duplex (Doppler) ultrasound scan is a non-invasive, painless test that combines a standard ultrasound scan with a Doppler assessment to create a colour map of your vessels and surrounding anatomy. Duplex ultrasound may be used to assess the shape and patency of both veins and arteries throughout the body and is a vital investigation in any vascular surgeon’s armamentarium.
What happens during a Duplex Ultrasound scan?
If you are undergoing an arterial duplex ultrasound you will be scanned whilst lying on a couch. For venous duplex ultrasound scans the individual performing the scan may require you to stand in addition. Once you are positioned comfortably lubricating jelly is applied to the region being scanned and a probe attached to the ultrasound machine is placed onto your skin. The probe emits ultrasonic sound waves which bounce off structures in your body according to tissue density. These echoes are detected by the probe and used to produce a detailed ‘live’ image of the inside of your body which is seen on the monitor. We will endeavour to point out areas of interest to our clients as the scan is performed.
How long does it take?
The scan takes 20-90 minutes but does depend on the area being scanned. A scan of the arteries in both legs and abdomen may take up to an hour and half to perform.
Are there any risks associated with undergoing a Duplex Ultrasound?
These scans do not involve radiation and are painless and safe. You will be able to return to work and drive immediately after the scan has been completed.
What happens after I’ve had a Duplex Ultrasound?
The scans are individually reported by our radiology team and reviewed with each client’s lead surgeon. You will then be reviewed in clinic to discuss the scan findings and how we may be able to help.
