Unexplained Leg Pain
Leg pain where the cause — arterial or venous — isn’t yet clear.
A combined arterial, venous and DVT assessment in a single visit — so both common causes of leg pain are evaluated together. No preparation required. Written report within 24 hours.
A combined arterial and venous Doppler assessment designed to investigate vascular causes of leg pain, swelling, heaviness, cramps, varicose veins, circulation concerns and suspected clot-related symptoms.

The Comprehensive Vascular Package for Leg Pain at London Private Ultrasound costs £449 for one leg or £599 for both legs. It combines a full arterial and venous Doppler assessment in a single appointment to investigate the vascular causes of leg pain — covering both the arteries (blood supply) and veins (drainage and reflux). No GP referral needed, same-day appointments, report within 24 hours.
All fees inclusive · no hidden costs
Assessment of one leg — ideal when symptoms affect only one side.
Assessment of both legs — for bilateral symptoms or full comparison.
| Component | What it grades | Standard threshold |
|---|---|---|
| Arterial (ABPI) | Peripheral arterial disease | ABPI ≤0.90 indicates PAD |
| Venous reflux | Chronic venous insufficiency | Reflux >0.5 s (superficial) / >1.0 s (deep) |
| DVT assessment | Deep vein thrombosis | Non-compressible vein indicates thrombus |
The leg-pain package combines arterial, venous and DVT assessment so both common causes of leg pain (arterial disease and venous disease) are evaluated in one visit, using the standard thresholds shown. Interpreted in full clinical context by our specialist vascular scientists.
| Measurement | What we assess | Why it matters |
|---|---|---|
| ABPI | Ankle-brachial pressure index. | Screens for peripheral arterial disease. |
| Venous reflux time | Reverse-flow duration in leg veins. | Diagnoses chronic venous insufficiency. |
| Vein compressibility | Whether deep veins compress fully. | Excludes deep vein thrombosis. |
| Doppler waveforms | Arterial flow patterns. | Localises arterial disease. |
Leg pain where the cause — arterial or venous — isn’t yet clear.
Cramping on walking that eases with rest (possible arterial).
Heaviness, aching and swelling (possible venous).
A combination of symptoms suggesting both systems.
You want a thorough one-visit vascular assessment of the legs.
Diabetes, smoking or known vascular disease.
A clear onward pathway matters. Your result is explained in plain English, with a written report suitable for your GP, specialist or insurer.
Graded by ABPI and waveforms, with GP or vascular referral as appropriate.
Mapped and graded, supporting referral for varicose-vein treatment.
A non-compressible vein suggests DVT — this is acted on urgently the same day.
Sudden cold, pale, pulseless limb, or hot swollen painful calf, needs emergency assessment (999).
This scan is supported by recognised clinical guidance and standard vascular practice.
Leg pain has both arterial and venous causes; combined duplex assessment allows accurate diagnosis in a single visit.
NICE CG147 (PAD) and CG168 (varicose veins).Same-day duplex assessment is valuable where DVT is part of the differential, as prompt diagnosis affects management.
Standard vascular practice.Clinical figures shown reflect standard, widely-used thresholds and are interpreted in full clinical context. For personal medical advice, consult your clinician.
