DVT Ultrasound Scan

Overview of DVT ultrasound scan

Helping to prevent complications such as pulmonary embolism, a DVT ultrasound scan is a safe, non-invasive imaging procedure used to assess blood flow in the veins and detect deep vein thrombosis (DVT). The scan provides detailed insight into the presence, location, and severity of blood clots. It is commonly performed on the legs but can also be used to examine other areas where DVT may be suspected. At The Forbury Clinic, our expert sonographers use advanced ultrasound technology to provide precise imaging and expert evaluation, ensuring accurate diagnosis and effective management of vascular conditions.

What is a DVT ultrasound scan?

A DVT ultrasound scan is a specialised imaging test used to detect deep vein thrombosis (DVT), a condition where blood clots form in deep veins, usually in the legs. This non-invasive procedure uses sound waves to create real-time images of blood flow, helping to identify vein blockages or abnormalities. It is a key diagnostic tool for assessing vascular health and preventing serious complications such as pulmonary embolism.

Why would you need a DVT ultrasound scan?

If a patient has symptoms of deep vein thrombosis, such as leg pain, swelling, warmth or redness, a DVT ultrasound may be necessary to assess blood flow and detect clots. The scan is also used for individuals at higher risk of blood clots due to factors like prolonged immobility, recent surgery or a history of clotting disorders. Early detection through ultrasound helps prevent serious complications, such as a pulmonary embolism, allowing for prompt and effective treatment.

How does a DVT ultrasound scan work?

Using high-frequency sound waves a DVT ultrasound scan creates real-time images of blood flow in the veins. A specialist applies gel to the skin and moves a handheld probe (transducer) over the affected area, sending sound waves that bounce back to form detailed images of the veins. This allows the specialist to assess blood flow, detect blockages and identify potential blood clots in deep veins.

Is a DVT ultrasound scan painful?

A DVT ultrasound scan is a painless and non-invasive procedure. The specialist may apply slight pressure with the probe, especially when assessing deeper veins, but this is generally well-tolerated. Any mild discomfort is temporary, and most patients find the scan to be a comfortable and straightforward experience.

How long does a DVT ultrasound scan take?

The scan typically takes between 20 and 45 minutes, depending on the area being examined and the complexity of the assessment. Once the DVT ultrasound is complete, initial findings may be available immediately, while a detailed report is usually provided within a short timeframe for further review by a healthcare professional.

What can a DVT ultrasound scan detect?

A DVT ultrasound scan is used to identify blood clots within deep veins, most commonly in the legs. It can also detect reduced blood flow, vein compressions or abnormalities in vein structure that may contribute to clot formation. Early detection of DVT is essential in preventing complications such as pulmonary embolism.

Are there any risks associated with a DVT ultrasound scan?

This ultrasound procedure is completely safe and risk-free, making it a reliable choice for assessing deep vein thrombosis. A DVT ultrasound scan does not use radiation or invasive techniques, ensuring patient comfort throughout. While some may feel slight pressure from the probe, there are no known side effects or health risks linked to this imaging method.
