Duplex Doppler Scan London: Vascular Ultrasound at SW11 Medical Clinic
If you’re looking for a precise and accessible vascular ultrasound in London, SW11 Medical Clinic in Clapham Junction offers expert Duplex Doppler scanning for arteries and veins. This non-invasive test maps blood vessels and measures flow in real-time to diagnose issues such as varicose veins, deep vein thrombosis (DVT), carotid artery narrowing, peripheral arterial disease (PAD), and venous insufficiency. With fast appointments, transparent pricing, and clear next steps, our clinic is designed to make your vascular care straightforward and stress-free.
- Duplex Doppler Scan: £340
- Endovenous Laser Ablation (EVLA) for varicose veins: from £1,200
- Surgical Consultation: £120
What is a Duplex Doppler Scan?
A Duplex Doppler scan is a specialist ultrasound that combines two technologies:
- B-mode ultrasound for clear images of blood vessels (structure and anatomy).
- Doppler ultrasound to measure the direction and speed of blood flow.
Together, these reveal whether vessels are open or blocked, if valves in leg veins are leaking (reflux), and how efficiently your circulation is working. The scan is non-invasive and painless, radiation-free (no ionising radiation), and safe for repeated monitoring.
Conditions a Duplex Doppler Scan Can Assess
- Varicose veins and venous insufficiency (assessing reflux and vein mapping for treatments like EVLA)
- Deep vein thrombosis (DVT) detection and follow-up
- Peripheral arterial disease (leg artery narrowing or blockages)
- Carotid artery disease (plaque and narrowing assessment)
- Abdominal aortic aneurysm surveillance
- Post-procedure monitoring after vein or arterial treatments
If you have leg pain, heaviness, ankle swelling, skin discoloration, non-healing leg ulcers, calf pain when walking, or a history of clots, a Duplex Doppler scan can be an essential first step.
Who Benefits from a Duplex Doppler Scan?
- Individuals with visible or symptomatic varicose veins
- Patients with leg pain on exertion (possible PAD)
- Those with leg swelling or tenderness (to help exclude DVT)
- People with cardiovascular risk factors (smoking, diabetes, high blood pressure, high cholesterol)
- Anyone advised to undergo vascular assessment before surgery or treatment
No GP referral is required to book at SW11 Medical Clinic.
What to Expect at SW11 Medical Clinic
We aim to make your visit efficient, comfortable, and informative. Here’s a typical pathway for our Duplex Doppler scan:
- Pre-visit guidance: When you book, our team clarifies the type of scan and shares any prep you may need. For leg vein scans, no special preparation is typically required. Wear loose clothing; you may be asked to change into a gown.
- Welcome and clinical review: On arrival, you’ll complete a brief health questionnaire. Our experienced vascular specialist will review your symptoms, medical history, and goals.
- The scan itself (20–45 minutes): You’ll lie comfortably on an examination couch. A water-based gel is applied to improve contact between the probe and skin. The clinician moves the probe along your neck, abdomen, or legs, gently compressing veins and performing manoeuvres to assess flow and valve function. For varicose veins, we map refluxing segments and mark target veins for potential treatments such as EVLA.
- Immediate feedback: You’ll receive a clear verbal explanation of the key findings right after the scan. A formal, detailed report with images is typically available within 24–48 hours.
- Next steps and treatment planning: If treatment is recommended, we’ll discuss options, timeframes, and costs, and can arrange a Surgical Consultation (£120). For varicose veins, our minimally invasive EVLA starts from £1,200.

Safety, Comfort, and Recovery
Duplex ultrasound is safe and well tolerated: no needles, no radiation, and no dye is typically required. Mild pressure from the probe may feel firm over tender areas but should not be painful. You can return to normal activities immediately after the scan.
Frequently Asked Questions
How long does a Duplex Doppler scan take?
Most vascular scans take 20–45 minutes depending on the area being assessed. A focused leg vein reflux study is typically 30–40 minutes, while multi-site assessments may take a little longer.
Is the Duplex Doppler scan painful or risky?
The scan is non-invasive and generally painless. You may feel light pressure from the probe. There is no ionising radiation and no routine need for contrast dye. Side effects are rare, and you can return to normal activities immediately.
Do I need to fast before my appointment?
For most leg vein or carotid scans, no fasting is required. For abdominal vessel scans (such as the aorta), you may be asked to fast for 4–6 hours to improve image quality. We’ll confirm any preparation when you book.
Will I get my results on the same day?
Yes—your clinician will explain the key findings straight after your scan. A detailed written report is usually sent within 24–48 hours, and we can provide copies for you and your GP.
What happens if my scan shows varicose vein reflux or arterial narrowing?
We’ll discuss tailored options. For varicose veins, EVLA from £1,200 is a common minimally invasive treatment. If arterial disease is identified, we’ll advise on medical optimisation, lifestyle changes, and when to consider interventions, arranging a Surgical Consultation (£120) if appropriate.
