Varicose Vein Diagnosis

Duplex ultrasound is very simply a way for doctors and surgeons to properly diagnose varicose vein conditions. 

A proper diagnosis is crucial to recommending the most appropriate treatment.

If you think you may have varicose veins, or know you have them and area considering treatment, then the first step would be to have a Duplex Ultrasound scan.


Ultrasound technology uses high-frequency sound waves to create an image of part of the inside of the body. It is commonly used during pregnancy to monitor the baby. It is also sometimes used in surgery, to guide the surgeon in certain procedures.

Ultrasound works by bouncing off any structures within the body, reflecting back to the machine, which uses special software to generate a black and white picture.

Duplex Ultrasound

Duplex ultrasound is more sophisticated and gives the surgeon much better detail. Duplex ultrasound combines the traditional grey ultrasound, overlaid with repeat images to show changes in real time.

In duplex ultrasound scanning, the scan is repeated in a fractions of seconds. The machine highlights any changes so that blood flow can be clearly seen as a real time movie.

So while an ultrasound may show the location of veins, a duplex ultrasound could show the flow of blood plus the direction and speed of flow

London Vein Treatment Centre

The London Vein Treatment Centre offers duplex ultrasound scan on site, so patients can visit and not need a referral for a scan elsewhere.

This enables the surgeon to give a much faster and more accurate diagnosis for the patient, so that they can discuss the symptoms and issues with the benefit of detailed information on the condition of the patient’s veins.

It enables an ‘informed decision’ to be made quickly on what treatment would be most appropriate.
