Left arterial doppler Lower limb, in Visit Clinic

Lower limb arterial Doppler is a non-invasive ultrasound test that uses Doppler sound waves to evaluate blood flow in the leg arteries. It detects narrowing, blockages, or reduced flow from peripheral arterial disease by generating blood-flow waveforms and velocity measurements. Typically painless and done outpatient, it helps diagnose causes of leg pain, ulcers, or poor pulses and guides treatment planning.

Normal findings on a lower‑limb arterial Doppler: an ankle–brachial index (ABI) of 1.0–1.4 (ABI ≤0.90 indicates peripheral arterial disease; 0.91–0.99 borderline; >1.4 suggests non‑compressible arteries). Doppler waveform is typically triphasic with a sharp systolic peak and brief diastolic reversal. If ABI is unreliable, a toe–brachial index >0.7 is generally considered normal.

In many countries the cost varies widely. On the UK NHS the arterial Doppler for lower limb is provided free; private clinics typically charge about £100–£350. In the United States self‑pay prices commonly range roughly $150–$800 (higher in some centers). In India typical lab charges are about ₹700–₹3,000. Exact fees depend on facility, region and included services.

A non-invasive Doppler test for the legs uses sound waves to assess blood flow in arteries and veins. It detects blockages or narrowing (peripheral arterial disease), blood clots (deep vein thrombosis), and venous insufficiency or varicose vein problems. Results guide diagnosis, treatment choices (medication, clot removal, or surgery) and monitor circulation after procedures or injuries.

A positive Doppler ultrasound means abnormal blood flow was detected. Next steps include confirmatory testing and specialist referral, urgent treatment if needed (for deep‑vein thrombosis: anticoagulants, compression stockings, monitoring; for arterial disease: medications, lifestyle changes and possible angioplasty or surgery). Close follow‑up, repeat imaging, and emergency care are required if signs of limb threat, pulmonary embolism, or fetal compromise occur.

Symptoms of a blocked artery in the leg include cramping, aching or tightness in the calf, thigh or buttock when walking (claudication), numbness, tingling or weakness, cold, pale or bluish skin, shiny skin and hair loss on the leg, weak or absent pulse in the foot, slow-healing sores or ulcers, and—if sudden—severe pain, numbness or paralysis indicating acute limb ischemia.
