In th those performing carotid duplex prior to a patient going to surgery. This current report presents the recommendations of that Working Group. In addition to recommending the diagnostic criteria to be used, attention is drawn to a number of issues that affect the accuracy of measure-ment and hence reliability of the investigation. It is 2010-09-07 · Although ultrasonic duplex Doppler methods are widely used in carotid artery diagnosis, there is disagreement about how the examinations should be performed and how the results should be validated.

Your doctor may recommend a carotid duplex ultrasound if they suspect carotid artery disease, in which the carotid arteries in your neck become narrow or blocked. Reduced blood flow through these arteries is a major risk factor for stroke. Carotid (kuh-ROT-id) ultrasound is a safe, painless procedure that uses sound waves to examine the blood flow through the carotid arteries. Your two carotid arteries are located on each side of your neck.

High-frequency sound waves are directed from a hand-held transducer probe to the area. carotid disease, carotid bruit, symptomatic peripheral arterial disease, coronary artery disease (CAD), atherosclerotic aortic aneurysm and those who have specific risk factors for carotid disease. Carotid duplex ultrasonography is not recommended for routine screening of asymptomatic patients who have no Carotid Duplex is a test that shows how well blood is flowing through the carotid arteries.

Additional clinically relevant criteria have also been developed, such as a threshold for the 70% to 99% North American Symptomatic Carotid Endarterectomy Trial (NASCET) stenosis. Carotid duplex ultrasound is the best non-invasive tool that can be used by health care providers to determine the presence of carotid stenosis.

The carotid arteries are located in the neck.

Carotid arteries are located in the neck and supply blood to your brain. Blockage or narrowing of the carotid arteries may lead to stroke.

Adequate evidence that duplex ultrasonography has reasonable sensitivity and specificity for detecting clinically relevant carotid artery stenosis.
