Duplex Ultrasound Scan
The duplex ultrasound scan is a painless and non-invasive
investigation and it takes only a few minutes to perform. The
surgeon at your initial consultation will perform the vein scan as
part of the examination.
The procedure begins with examining your groin area to check
the status of the deep vein and the arterial circulation. Then your
superficial veins are checked to assess if they had valve damage
that causes backpressure to form varicose veins. The
examination is then carried down over the bulging veins to see
the points of communication with the leaking internal vein. The
sites of deep perforating and communicating veins are
documented. Identification of the source of the varicose veins
accurately enables the specialist to plan appropriate treatment
that reduces the risk of future recurrence.
The test is usually performed in a standing position that helps to
fill the veins. Occasionally it is also performed sitting down or
lying on the couch. It is advisable to wear comfortable clothing
that would allow easy exposure and avoid moisturisers on the
leg on the day of consultation. A water-soluble gel is used during
the examination and this is easily washed off and does not stain
clothes.
