What is a Deep Vein Thrombosis (DVT) scan?

A DVT scan is a diagnostic ultrasound test used to detect blood clots in the deep veins, usually in the legs. It helps diagnose Deep Vein Thrombosis, a condition caused by blood clots blocking veins.

Why is a DVT scan performed?

A DVT scan is done when symptoms such as leg swelling, pain, redness, or warmth suggest a possible blood clot in the deep veins, to confirm diagnosis and guide treatment.

How is the DVT scan performed?

An ultrasound probe is moved over the skin of the affected leg. It uses sound waves to create images of veins to detect any blockages or clots without pain or radiation.

Is the DVT scan safe?

Yes, the scan is non-invasive, painless, and uses ultrasound technology without any radiation exposure.

How should I prepare for a DVT scan?

No special preparation is usually required. Wear loose clothing and avoid applying lotions to your legs before the scan.

How long does a DVT scan take?

The procedure usually takes about 15 to 30 minutes.

What happens after the DVT scan?

A radiologist reviews the images and sends a report to your doctor, who will discuss the results and next steps with you.

What is Deep Vein Thrombosis (DVT Scan)

Deep Vein Thrombosis (DVT) is a serious condition where a blood clot forms in a deep vein, usually in the legs. If left untreated, the clot can travel to the lungs, causing a pulmonary embolism (PE), which can be life-threatening. A DVT scan is a safe and effective way to detect these clots early and prevent complications.

What Is a DVT Scan?

A DVT scan is a non-invasive ultrasound test that uses sound waves to create images of the veins in your legs or arms. This helps doctors identify blockages caused by blood clots.

Why Is a DVT Scan Important?

DVT can develop without obvious symptoms, making early detection through a scan crucial. If diagnosed early, treatment can prevent the clot from growing or breaking loose.

Signs and Symptoms of DVT

Seek medical attention if you experience:

Swelling in one leg or arm
Pain or tenderness, especially in the calf
Warm skin over the affected area
Red or discolored skin
Enlarged veins

If you experience chest pain, difficulty breathing, or coughing up blood, seek emergency medical help immediately, as these could be signs of a pulmonary embolism.

Who Should Get a DVT Scan?

A DVT scan is recommended for those with:

Prolonged immobility, such as long flights, bed rest, or post-surgery recovery
Pregnancy or recent childbirth
A history of blood clots
Medical conditions such as cancer or clotting disorders
Hormone therapy or birth control use
Recent leg injury or surgery

How Is a DVT Scan Done?

The most common test for DVT is a vascular ultrasound, which involves:

Applying a gel to the skin to help transmit sound waves
Moving a small probe (transducer) over the skin to capture images
A doctor reviewing the images to check for blood clots or abnormal blood flow

The scan is painless, takes about 30 minutes, and provides quick results.

What Happens If DVT Is Found?

If a clot is detected, treatment may include:

Blood thinners to prevent further clotting
Compression stockings to improve circulation
Lifestyle changes such as staying active and hydrated
In severe cases, procedures to remove the clot

Prevention Tips

Stay active and avoid prolonged sitting
Drink plenty of water to stay hydrated
Wear compression stockings for long-distance travel
Maintain a healthy weight
Follow medical advice if you are at risk of DVT
