Private Deep Vein Thrombosis (DVT) Ultrasound Scan
About the DVT Ultrasound Scan
A DVT scan or Venous Doppler or Duplex ultrasound is an imaging examination which is being used to check for any clots or thrombus in the veins that can cause blockage. Clots can develope within the deep veins of the body but mainly the legs and ultrasound is being used to confirm or exclude the presence of DVT.
DVT can cause pain and swelling in one or both legs and has the potential of causing a life threatening pulmonary embolism. Pulmonary embolism is being caused when a piece of the thrombus breaks off and travels to the pulmonary vessels in the lungs and blocks them.
What is the purpose of the DVT ultrasound scan?
The DVT scan includes evaluation of:
Deep calf veins (if visualised)
Reasons for having a DVT ultrasound scan:
In some cases, there may be no symptoms of DVT. If symptoms do occur they can include:
Pain, swelling and tenderness in one of your legs
A heavy ache in the affected area.
A warm skin in the area of the clot.
Redness of your skin, particularly at the back of your leg below the knee.
What is included with the deep vein thrombosis ultrasound scan
A written ultrasound report and if needed, a follow up recommendation.
No preparation for this deep vein thrombosis ultrasound scan is neccesary.
What should I expect during the DVT ultrasound scan procedure?
Upon your arrival our sonographer will explain the ultrasound examination procedure. You will need to expose your legs and a small amount of gel will be placed on your skin. The sonographer will follow the length of your leg veins and from time to time you will feel a small amount of pressure. Sometimes you might see colour on the screen or hear a noise. The colour is called colour Doppler and used to see the blood flowing through your veins. The 'noise' is again a technique to evaluate the blood flow and it is called Pulse Wave Doppler. A combination of the greuscale image, the colour doppler and pulse wave doppler is called triplex doppler.
The ultrasound examination should last approximately an hour and an ultrasound report will be issued to take it with you.
