The most common diagnostic investigation performed on patients with varicose veins is an ultrasound venous Doppler test. This is similar to the ultrasound used to perform
abdominal and pregnancy scans.

A venous Doppler test gives an anatomical and functional view of the veins of the leg. The test relies on the skill of the operator to be successful and can reveal information about the damaged and normal veins, the size of the veins, together with the site of the damaged perforator veins which connect the deep veins to the superficial veins. 

At Varicose Veins clinic, all venous Doppler scans are performed by our varicose veins specialist and the findings documented.  

This is vital for two reasons:

The first is for the staging of the varicose veins, which is done based upon the clinical and venous Doppler scan findings.
The second, by performing the venous Doppler scan himself, the doctor can effectively plan sclerotherapy or EVLT along with the number of veins to be treated and the length of the veins to be treated by EVLT and sclerotherapy. 
The decision about the management of varicose veins and the type of treatment required ultimately depend upon the correctly performed venous Doppler scan findings.
