Vascular ultrasound uses duplex imaging to evaluate blood flow in arteries and veins. At Atrium Vascular Associates, board-certified vascular and endovascular surgeon Dr. Sydney Wong carefully reviews your results to guide individualized, evidence-based vascular care.
Detect Blockages and Flow Abnormalities
Vascular ultrasound is a noninvasive imaging test that uses sound waves to evaluate blood flow through your arteries and veins. Using duplex technology, it produces real-time images of your blood vessels and measures blood flow through them. This allows Dr. Wong to identify narrowing, blockages, blood clots, valve dysfunction, and other circulation problems. These studies are performed off-site and carefully reviewed by Dr. Wong to guide accurate diagnosis.
What Does a Vascular Ultrasound Diagnose?
A vascular ultrasound helps diagnose a wide range of circulation problems. It allows your team to identify narrowed or blocked vessels, reduced blood flow, blood clots, and malfunctioning vein valves without invasive testing. These findings are essential for understanding the root cause of vascular symptoms, assessing disease severity, and guiding appropriate next steps in care, whether monitoring, medical management, or procedural treatment. You may need a vascular ultrasound if:
- You experience leg pain, cramping, or fatigue with walking
- You have swelling, heaviness, or visible vein changes
- You develop unexplained leg pain, warmth, or tenderness
- You notice skin discoloration or slow-healing wounds
- You have risk factors for vascular disease or prior vascular conditions
Why Choose Dr. Sydney Wong?
Dr. Sydney Wong is a board-certified vascular and endovascular surgeon with advanced expertise in interpreting arterial and venous imaging. He carefully reviews vascular ultrasound studies to correlate imaging findings with your symptoms, medical history, and physical exam. This physician-led interpretation helps ensure your results are not viewed in isolation, but used thoughtfully to guide accurate diagnosis and individualized treatment recommendations.
What to Expect During a Vascular Ultrasound?
During a vascular ultrasound, you’ll lie comfortably while a trained technologist applies a small amount of gel to the skin over the area being examined. A handheld probe is moved across your skin to capture real-time images and measure blood flow. You may hear whooshing sounds as blood flow is recorded. The test is painless, noninvasive, and involves no radiation. Your study is conducted off-site and then reviewed by Dr. Wong to guide the next steps.
Benefits of a Vascular Ultrasound
A vascular ultrasound offers detailed insight into your circulation without invasive testing, making it a valuable first step in evaluating vascular symptoms. Key advantages include:
- Noninvasive imaging without needles or incisions
- No radiation exposure
- Ability to evaluate both arteries and veins
- Real-time assessment of blood flow and vessel structure
- Helpful guidance for diagnosis, monitoring, and treatment planning
Vascular Ultrasound FAQs
Do I Need to Prepare for a Vascular Ultrasound?
Preparation depends on the area being examined. For most leg or arm ultrasounds, no special preparation is needed. If your abdomen is being evaluated, you may be asked to fast for several hours beforehand to reduce gas that can interfere with imaging. Our team will give you clear instructions in advance so you know exactly what to expect.
What Conditions Can Vascular Ultrasound Help Monitor Over Time?
Vascular ultrasound is commonly used to monitor peripheral artery disease, chronic venous insufficiency, prior blood clots, aneurysms, and post-procedure results. Repeating the same study over time allows your vascular care team to track changes in blood flow and vessel health, helping guide decisions about ongoing management or intervention.
What Happens After My Ultrasound is Completed?
After your study, Dr. Wong will review the images and measurements and discuss the results with you. If an issue is identified, he’ll explain what it means in clear, practical terms and outline the appropriate next steps. All recommendations are individualized to you, whether that means ongoing monitoring, lifestyle guidance, medical therapy, or procedural treatment.
