Vascular Ultrasound to Exclude DVT

Venous Ultrasound is used as a non invasive tool to exclude deep vein thrombosis (clot) as a cause for pain and swelling in the lower limb. The scan quality can be limited by severe swelling.

Preparation

There is no special preparation for this test. Just wear suitable clothing to allow access to the entire leg, from groin to calf. No other preparation is required.

What will happen during the procedure?

You will be positioned lying face-up on an examination table that can be tilted or moved. A clear water-based gel is applied to the leg to help the transducer make secure contact with the body and eliminate air pockets between the transducer and the skin that can block the sound waves from passing into your body. The radiologist then places the transducer over the veins until they have been examined and the desired images captured.

What will I experience during the procedure?

There is usually no discomfort from pressure as the transducer is pressed against the area being examined. However, if scanning is performed over an area of tenderness, you may feel pressure or minor pain from the transducer. Once the imaging is complete, the clear ultrasound gel will be wiped off your skin. Any residual gel will dry to a powder. The ultrasound gel does not stain or discolour clothing.

How long does the procedure take?

The procedure should be complete within 15-20mins. After an ultrasound examination, you should be able to resume your normal activities immediately.

When will I get my results?

The report will be faxed to your referring doctor within 2 hours of your examination.
