Duplex Diagnosis of Varicose Veins
Varicose veins are easy to recognize, but if there are larger varicose veins then additional examination is needed. Varicose veins on the outside of the leg can be the result of valves leaking in the depth. This must first be examined; this examination is usually called a phlebo-diagnosis. During this examination the location of the varicose veins, the type of varicose veins and the best treatment are assessed.
The examination for varicose veins is carried out in a standing position, because then they fill up and are clearly visible. First we look at where the varicose veins run and whether they are large or smaller. Using a Duplex device (echo-Doppler) we look at the valves in the veins and at the direction of the blood flow. With the Duplex device it is also possible to see if there are vessels closed with clots (thrombosis) and if the deep vein system is good.
This is determined on the basis of the findings during the investigation. If you only have small varicose veins on the outside of the leg, then injecting (sclerosing) is the best solution. If there are very small ones in between, so small that a needle doesn't fit, they can be treated with an external laser treatment. For medium-sized varicose veins, sclerosis is also the ideal solution. For the very large varicose veins, there are other treatments than sclerosing.
