During an ultrasound, high-frequency sound waves are transmitted through body tissues. The echoes which bounce back to the receiver are then recorded and translated into photographic images and video.
Images can be viewed in real time via a television monitor, or they can be recorded for future study. By examining the images, practitioners can get a detailed view of what is happening inside the patient’s body which will help them to develop a procedure that can rectify any problems.
Ultrasound technology is now used to diagnose a wide range of diseases including Vein treatment.
Arteries are the blood vessels which pump oxygen-rich blood throughout the body. Blood from the arteries flows through small blood vessels known as capillaries, where the oxygen in the blood is then transferred over to the body’s tissues.
Veins then carry the blood back to your heart where it can collect more oxygen, and the cycle continues. Veins contain a one-way valve to prevent blood flowing backward and to keep it moving in one direction towards your heart.
If a valve becomes weak or damaged, then blood can pool in the vein, causing it to swell and turn varicose.
Why Do I Need an Ultrasound?
Varicose veins are an unsightly and often painful condition. After a vein has turned varicose, it serves no useful purpose as the body has already re-routed blood flow.
Many factors may increase the likelihood of varicose veins, including pregnancy, obesity, gender, family history, and a sedentary lifestyle.
While many varicose veins can be treated with lifestyle changes, there are medical procedures which can help to improve the appearance of varicose veins, prevent complications from an underlying circulatory problem, and to relieve symptoms such as pain and discomfort.
Painful symptoms of varicose veins may include a burning sensation, muscle cramping and throbbing, swelling of the lower legs, and worsening pain as you sit or stand in one position for extended periods of time.
Veins just below the skin are visible to the naked eye and are less common. Varicose veins below the skin are not detectable with just a visual examination, so an ultrasound test is used to determine their condition.
What Happens During an Ultrasound Mapping to Map Veins
An ultrasound procedure is performed to “map” all the leg veins. During the ultrasound mapping procedure, the technologist will use the equipment to measure the leg vein and then mark your skin to indicate to the surgeon the exact location.
An ultrasound mapping examination will take around 30 minutes. The procedure is performed while you are standing, as maintaining this position makes it easier to see the veins. You can wear your own shorts if they are loose fitting. However, if your attire is not appropriate for an accurate ultrasound, you will be provided a loose-fitting gown or laundered shorts.
What is the Doctor Looking for During an Ultrasound?
Doppler assessments which make the blood flow through the leg veins visible on a screen are done to determine the direction of flow. Any veins which allow blood to flow backward are not working and are assessed for possible laser treatment, with veins that are straight and over 6mm being good candidates.
The two superficial systems where varicose veins occur; the Short (or Small) Saphenous Vein starting from the knee and travelling the outside ankle, and the Greater Saphenous Vein travelling from the groin to the inside ankle, are examined to determine their condition. Both these systems are mapped using ultrasound. Once the mapping is complete, a deep vein thrombosis (DVT) examination is performed to check for blood clots.
