Doppler Arterial Lower Limb - Left Ultrasound Scan

What the Test Shows

• Real-time blood flow speed and direction in the left leg arteries
• Narrowings (stenosis), blockages, or plaques before they cause pain
• Post-surgical graft or stent performance

How Long It Takes

20–30 minutes from check-in to checkout.

Why Cadabams Diagnostics

• NABL-accredited lab with high-resolution ultrasound systems
• Report ready within 2 hours
• Friendly staff trained to make seniors and diabetics comfortable

Definition in Simple Terms

A Doppler arterial scan uses sound waves to create moving pictures of blood traveling through the arteries of your left lower limb. It shows how and how fast blood is moving—something a regular ultrasound cannot do.

Difference Between Standard Ultrasound & Doppler

• Color Doppler – overlays color on the image to show speed and turbulence
• Spectral Doppler – displays a waveform graph for precise velocity measurements
• Power Doppler – extra-sensitive for detecting slow flow in tiny vessels, used when blockages are suspected

• Evaluate claudication – pinpoint level of blockage causing leg pain
• Pre-surgical mapping – plan bypass or angioplasty routes
• Monitor bypass grafts & stents – ensure they stay open

Common Symptoms Prompting the Scan

• Pain or cramping in the left calf, thigh, or buttock while walking (claudication)
• Cold or pale left foot
• Non-healing ulcers or blackened toes
• Weak or absent left leg pulse

High-Risk Groups

• Diabetics – high sugar injures artery walls
• Smokers – nicotine causes vessel spasm and plaque
• Seniors over 60 – natural aging thickens arteries
• People with high blood pressure or cholesterol

• Non-invasive & painless – gel and a probe only
• Real-time blood-flow imaging – watch your pulse live on screen
• Same-day results at Cadabams – leave with a report and doctor consult

• Peripheral Artery Disease (PAD) – early detection prevents limb loss
• Arterial occlusions – complete or partial blockages
• Diabetic microangiopathy – small vessel damage in long-standing diabetes

• Clothing: wear loose shorts or pants you can roll up easily
• Medications: continue all prescriptions, including blood thinners
• Remove jewelry from the left leg only

• Fasting not required – eat normally
• Bring any prior angiography or ultrasound reports to compare progress
• Inform front desk if you have a pacemaker (not contraindicated, but we note it)

• Morning slots preferred for diabetic patients – stable blood sugar after breakfast
• Avoid caffeine 2 hours before – it can temporarily speed up blood flow and skew readings

• Adults & elderly – routine screening or symptom investigation
• Pediatric cases by referral only – rare but possible in congenital malformations

• Inform about open wounds or ulcers – we use sterile probe covers
• Pacemakers & metal implants – safe; just let us know for documentation
• No sedation – drive home or back to work immediately after

• Zero radiation exposure – safe for repeated follow-ups
• Non-invasive – no needles, contrast, or dyes
• Possible challenges: very obese patients may need lower-frequency probes for deeper vessels; open wounds are covered with sterile drapes to prevent infection risk
