A venous reflux ultrasound maps the leg veins and assesses blood flow direction. It is used for varicose veins, persistent heaviness, aching, swelling and discussion of an appropriate vein-treatment pathway.
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 Venous Reflux Ultrasound Can Assess
The examination maps the veins and supports a clinical decision about conservative measures, specialist review or potential treatment. It does not replace urgent assessment for sudden possible DVT symptoms.
| Area assessed | Why it may be examined |
|---|---|
| Superficial veins | Vein anatomy and reflux-related flow |
| Deep veins | Relevant deep venous flow and patency features |
| Varicose tributaries | Visible surface-vein distribution |
Preparation Before Your Appointment
No fasting or bladder preparation is required. Please wear loose trousers, shorts or a skirt; you may be asked to stand for part of the examination.
Preparation summary: No special preparation — You may be scanned standing; wear loose clothing.
What Happens During the Scan
The sonographer uses Doppler imaging while you are lying down and/or standing. Brief pressure or movement manoeuvres can be used to assess how blood flows in the veins.
- 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
Seek urgent assessment for new one-sided leg swelling, pain or warmth; a painful red hard vein with systemic symptoms; chest pain; shortness of breath; or coughing blood.
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.
