Carotid Ultrasound Dayton, OH

Carotid Ultrasound An Overview

A carotid ultrasound is a non-invasive, painless, and safe procedure that uses sound waves to analyze the blood flow through the carotid arteries. The carotid arteries move blood from the heart to the brain.

A carotid ultrasound can help identify narrowed or blocked arteries. The carotid arteries may narrow due to plaque buildup which may increase a patients’ risk of stroke or other complications.

Why is a carotid ultrasound is performed?

A carotid ultrasound helps your physician assess the amount and speed of blood flow through the carotid arteries to determine the degree of blockage. A carotid ultrasound is performed if you have had a transient ischemic attack or stroke. Your physician may order carotid ultrasounds to check the arteries for blood clots, plaque buildup, or blood flow problems.

What are the symptoms of a blockage in the carotid artery?

There are many symptoms to look out for if you believe you have a blockage in the carotid artery. Common reasons your doctor may recommend a carotid ultrasound to evaluate these symptoms include:

  • High blood pressure
  • High cholesterol
  • Trouble speaking
  • Sudden vision problems
  • Diabetes
  • Dizziness
  • Medical conditions that increase the risk of stroke
  • Family history of heart disease
  • Severe headaches
  • Recent stroke
  • Facial drooping
  • Abnormal sound in carotid arteries
  • Coronary artery disease
  • Sudden weakness or numbness in the face, arms, or legs

What happens after a carotid ultrasound?

If we determine that you have a blocked carotid artery, we will recommend carotid artery surgery or carotid endarterectomy. A doctor will remove the buildup of plaque that has clogged the artery. You will not need to be put to sleep with general anesthesia. You will be administered local anesthesia so that you do not feel pain or discomfort.

How long does a carotid ultrasound take?

On average a carotid ultrasound takes around 30 to 60 minutes but with wait and check-in times it may take longer. A carotid ultrasound graphs the blood flow through arteries. In order to see an accurate graph of the blood flow radiologists usually want to take the ultrasound for at least 30 minutes to get a full picture of the internal flow.

What is a normal carotid ultrasound result?

The typical carotid ultrasound results are reported as being normal when there is clear blood flow, and little or no narrowing of the arteries. When arteries are narrow, they can be reported as a percentage. For example, 70% stenosis is a bad reading from a carotid ultrasound.

What happens during a carotid ultrasound?

During a carotid ultrasound, the doctor will put gel on the skin around the area they are looking to examine, and then they use a probe to view the artery. The probe sends out waves that bounce off the arteries to produce a live image of blood traveling through the artery.

Carotid Ultrasound What to Expect

How To Prepare

Your physician will explain all aspects of the procedure with you during your evaluation. In most cases, patients will not need to follow any strict preparation requirements before their carotid ultrasound.

What To Expect

During a carotid ultrasound, you will lie on your back for the duration of the testing.  You will need to remove any jewelry, clothing, or objects that may interfere with testing. Your technician will apply a small amount of gel to the ultrasound transducer and gently glide it across each side of the neck to obtain images of the arteries. Your technician may ask you to move the head or neck to collect different images of the arteries.

Once the ultrasound is completed, your technician will wipe away any excess gel. Typically a carotid ultrasound takes 30-60 minutes. Your physician will analyze the results from the carotid ultrasound and determine if further testing or treatment is needed.
