Arterial Duplex Ultrasound
An arterial duplex ultrasound is a non-invasive, entirely painless diagnostic imaging test used to evaluate the health of the arteries in your legs. While veins bring blood back up to the heart, arteries are the vital highways that carry oxygen-rich blood down to your tissues. This specialized scan combines traditional ultrasound imaging with Color Doppler technology to create a clear, moving picture of your arterial blood flow.
Performed entirely in our comfortable office setting at the Vein & Wound Center of LA, this precise diagnostic test pinpoints exact arterial blockages, plaque buildups, and circulation narrowing to ensure your leg tissues receive the oxygen they need to heal and function without pain.
When lower leg arteries become narrowed or blocked, tissues are starved of oxygen, causing distinct physical warning signs. This diagnostic scan is highly recommended if you experience:
Painful Leg Cramps While Walking (Claudication): A sharp, tight, or burning cramp in your calf, thigh, or buttocks that starts predictably during walking or exercise but fades after a few minutes of rest.
Severe Foot Pain at Night: A severe, burning pain in your toes or the arch of your foot that wakes you up at night, especially when your legs are flat in bed, but feels better when you let your legs dangle over the edge.
Non-Healing Wounds on Toes or Heels: Deep, round open sores with pale or yellow wound beds that fail to heal, usually forming on the tips of toes, heels, or outer ankle bones.
Cold, Pale, or Shiny Leg Skin: Lower legs and feet that feel unusually cold to the touch, look pale or white when lifted up, or have thin, shiny skin with sudden hair loss.
An arterial duplex ultrasound utilizes the physical laws of the Doppler Effect to simultaneously map out your regional circulation dynamics and evaluate the physical structure of your blood vessels.
During the test, you will lie comfortably on an examination table. Our vascular specialist applies a warm gel to your legs and glides a small hand-held device called a transducer across your skin surface along the natural paths of your arteries, from your groin down to your toes.
The transducer sends safe, silent sound waves deep into your tissue layers. When these sound waves hit moving red blood cells inside your arteries, they bounce back to a specialized computer. The “duplex” part of the test means it does two things at once: it provides a 2D structural image of the artery wall to reveal any hardened fatty plaque buildups (atherosclerosis), while simultaneously color-coding the blood flow to measure its exact speed and volume. If an artery is severely narrowed, the computer hears a telltale high-pitched, fast sound wave, pinpointing the exact spot where your leg tissue is being starved of oxygen.
Our detailed in-office arterial duplex protocol scans your complete lower extremity arterial network to map out blood delivery:
1.Atherosclerosis and Plaque Mapping:
Plaque Check. We scan your vessel walls to locate fatty calcium deposits, measuring exactly how much the plaque buildup is narrowing the internal diameter of your leg arteries.
2.Blood Flow Velocity Measurement:
Speed Test. We calculate the exact speed of your blood flow across multiple leg segments; a sudden spike in blood velocity reveals a tight bottleneck or severe restriction.
3.Ankle-Brachial Index (ABI) Integration:
Ratio Check. We often combine the ultrasound with blood pressure cuffs on your arms and ankles to compare your pressure levels and officially grade the severity of Peripheral Artery Disease (PAD).
4.Surgical and Healing Roadmaps:
Plan Creation. We chart your exact blockages, creating an accurate map that our medical team uses to safely plan your wound care or quickly coordinate an outside referral to top local vascular surgeons if a vessel needs to be surgically reopened.
When it comes to complex arterial health and saving threatened tissues, you deserve specialized, expert care:
Our specialists possess advanced training in both vascular medicine and complex wound care, allowing them to rapidly trace surface skin ulcers back to deep arterial circulation failures
We perform your complete arterial assessments, high-resolution color imaging, and subsequent wound treatments right here under one comfortable roof.
You do not have to wait weeks for a lab report; our medical team reviews your real-time flow charts during your session to explain your circulation health immediately.
We ensure your test is entirely safe and low-stress, using warm scanning gels, comfortable positioning, and an exceptionally gentle touch designed to protect highly tender or cold feet.
No. It is completely painless and non-invasive. It uses safe sound waves to see inside your leg, meaning there are absolutely no needles, contrast dyes, or radiation involved.
Lying flat allows us to accurately measure the resting pressure and natural speed of blood traveling from your heart down to your feet without gravity altering the baseline numbers.
A detailed arterial scan for one leg usually takes between 30 and 45 minutes, as the specialist must carefully trace multiple artery segments from your groin down to your toes.
PAD is the narrowing of the arteries in your legs due to plaque buildup. This ultrasound finds PAD by visually showing the plaque on the screen and measuring where blood flow slows down or gets blocked.
If a severe blockage is found, we immediately build a protective plan for your leg and rapidly coordinate a referral to elite local vascular surgeons to discuss minimally invasive options to reopen the vessel.
Don’t let visible veins or self-consciousness hold you back from living your life to the fullest.
