A DVT ultrasound uses Doppler imaging to assess the deep veins of the leg when symptoms such as new one-sided swelling, pain, warmth or tenderness raise concern about a blood clot.
Ultrasound uses sound waves rather than ionising radiation to create real-time images. Your examination is selected around your symptoms, clinical history and the body area that needs assessment.
At Victoria Medical, the scan is performed through an appropriate clinical pathway. The sonographer will explain the practical steps, and you will receive clear information about reporting and any recommended follow-up.

What a DVT Ultrasound Scan Can Assess
This is a time-sensitive examination. The most appropriate pathway depends on your symptoms and risk factors; the clinic team can advise on urgency, but emergency symptoms require urgent services.
| Area assessed | Why it may be examined |
|---|---|
| Deep veins | Compressibility and blood-flow features in the leg veins |
| Symptom area | Relevant veins in the painful or swollen limb |
| Other visible findings | Some alternative soft-tissue causes of symptoms |
Preparation Before Your Appointment
No fasting or bladder preparation is needed. Please wear loose clothing and bring a list of medicines, especially anticoagulants, if you take them.
Preparation summary: Urgent pathway — New or worsening symptoms may need same-day assessment — call us now.
What Happens During the Scan
Gel is applied to the leg and a probe is moved along the relevant veins. Gentle pressure is used as part of the assessment. The team will explain the next step once the examination is complete.
- Bring any relevant referral letter, previous scan report or test result if you have one.
- Wear clothing that allows straightforward access to the area being examined.
- Tell the clinical team if you are unsure whether this is the right scan for your symptoms.
Results and Next Steps
The examination forms one part of your clinical assessment. Your report and the appropriate next step will depend on the scan findings, your symptoms and relevant history. We can help arrange GP, specialist or urgent-care follow-up where this is clinically appropriate.
When to Seek Urgent Medical Help
Call 999 immediately for chest pain, shortness of breath, coughing blood, collapse or severe sudden deterioration. For new one-sided leg swelling or pain, contact the clinic or an urgent medical service without delay.
Ultrasound is not a substitute for emergency assessment. If symptoms are severe, sudden, worsening or accompanied by fainting, breathing difficulty, fever, heavy bleeding or acute testicular pain, seek urgent medical help.
