This course introduces the use of diagnostic imaging with the use of Doppler for examining the vasculature of the human body. In this class, the student will learn about diseases that affect the circulatory system. The course provides a history of diagnosis and treatment of vascular conditions. In addition, the course gives the student an awareness of alternative diagnostic tools used in conjunction with ultrasound. The student will learn how to perform vascular tests commonly performed in vascular laboratories and develop an awareness of tests that are routinely performed.

• Demonstrate knowledge of ultrasound physics and instrumentation.
• Demonstrate knowledge of Doppler and vascular physics and instrumentation.
• Demonstrate knowledge of normal and abnormal vascular anatomy.
• Understand vascular physiology, pathophysiology, and hemodynamics.
• Recognize signs, symptoms, etiology, complications, and sequela of peripheral vascular disease.
• Describe various other modalities used to diagnose peripheral vascular disease and their efficacy. List first-line drugs in the treatment of vascular disease.
• Students will observe a professional attitude and appearance at all times.
• Perform appropriate examination protocols and proper evaluation of vessels being studied.
• Students will attend class and lab prepared to acquire knowledge of the subject that will be presented in class.
• Students will recognize the needs of the patient and the ethics of the profession of sonography.

What is a vascular ultrasound?

Vascular ultrasound, also called a duplex study, is a noninvasive test. This test shows healthcare providers how blood flows in your arms, neck, and legs. High-frequency sound waves create detailed images of soft tissue and blood vessels.

When is a vascular ultrasound performed?

Your healthcare provider may use vascular ultrasound to see how blood flows through your veins and arteries (blood vessels). You may have this test to help your provider diagnose:

• Blood clots.
• Carotid artery disease.
• Chronic venous insufficiency.
• Deep vein thrombosis.
• Extracranial carotid artery aneurysm.
• Peripheral artery disease.
• Vascular disease.
• Varicose veins.

When would I need a vascular ultrasound exam?

You may need a vascular ultrasound if you have symptoms like:

• Burning feeling in your legs.
• Muscle atrophy.
• Pain in your buttocks, hips, thighs, or calves.
• Leg sores (ulcers) that don’t heal.

Healthcare providers also use vascular ultrasound to check blood flow to organs. You may have this test if you’ve received an organ transplant.

Providers may also order a vascular ultrasound exam to see if you’re a good angioplasty candidate or check blood vessel health after venous disease bypass surgery.

Who performs a vascular ultrasound exam?

An ultrasound technologist performs your vascular ultrasound exam. These technologists have special training in performing ultrasound tests.

Test Details

How does vascular ultrasound work?

Vascular ultrasound uses high-frequency sound waves to create detailed images. These sound waves pass through your soft tissues and blood vessels. Sound waves create echoes as they pass through tissue and computers turn these echoes into images or videos.

How do I prepare for a vascular ultrasound?

There’s nothing special you need to do to prepare for a vascular ultrasound. Plan to arrive at the facility about 15 minutes before your vascular ultrasound appointment.

You should wear comfortable and loose-fitting clothing and leave any jewelry or valuables at home. Healthcare providers may ask you to change into a hospital gown.

What happens during a vascular ultrasound?

You lie on an examination table. The technologist applies a lubricating gel to your skin in the areas where they will examine your arteries and veins.

The technologist places a special probe called a transducer against your skin. You might feel a little pressure as they move the probe over the area. You may hear your blood flowing as it makes a pulsing or whooshing sound.

What should I expect after the vascular ultrasound?

When the exam is over, the technologist wipes the lubricating gel away. You can return to work or other activities immediately after your exam.

Does vascular ultrasound have any risks or side effects?

Vascular ultrasound is safe. You won’t have any side effects from the exam.
