Ultrasound Mapping
Ultrasound mapping of veins, also known as venous ultrasound or venous duplex ultrasound, is a non-invasive medical imaging technique used to visualise and assess the veins in the body. It is commonly used to evaluate the condition of veins in the legs, arms, and other parts of the body. This imaging technique combines two types of ultrasound: B-mode ultrasound, which creates a two-dimensional image of the vein structure, and Doppler ultrasound, which assesses blood flow within the veins.
Before the ultrasound mapping of the veins, you will be given a gown or laundered shorts to put on or you can bring your own shorts but they must be loose-fitting. The ultrasound is performed with you standing as this makes the veins easier to see. The ultrasound mapping assessment starts in the groin, at the origin of the great saphenous vein.
A Doppler assessment is made to check the direction of blood flow down the leg. This is done by squeezing the calf and watching the direction of blood flow on the screen. There are valves placed along the vein to prevent the blood from falling backwards down the leg. If the Doppler can show the blood is falling backwards down the leg then the vein is not working or is incompetent. The diameter measurement of the vein is recorded and assessed to see if it is suitable for laser. We can laser incompetent veins (not working normally) that are over 5mm and straight.
All the veins around the leg are assessed and recorded on a map. There are two superficial systems where varicose veins come from: the great saphenous vein (GSV) which starts in the groin and travels down the leg to the inside ankle, and the small saphenous vein (SSV) which starts from behind the knee and travels to the outside ankle. These two systems are assessed to see whether they are competent. After the mapping of both legs is completed, a deep vein thrombosis (DVT) study is performed on both legs routinely to check for blood clots. When the mapping is complete, the doctor will consult with you again to go over your treatment options.
