Located in the side of your neck, your left and right carotids are two large arteries that carry This article focus on internal carotid artery (ICA) stenosis, reporting both criteria: the one published by Society of Radiologists in Ultrasound 2 and the Sonographic NASCET Index 1. Please refer to the article on extracranial carotid artery stenosis for a general discussion involving carotid stenosis and other image modalities involved on it. Adequate evidence that duplex ultrasonography has reasonable sensitivity and specificity for detecting clinically relevant carotid artery stenosis. However, duplex ultrasonography yields many false-positive results when screening the general population.

The decision to offer surgical inter-vention is often dependent on duplex velocity in addition to patient presentation. Computer tomographic arteriography Carotid artery atherosclerosis as measured by IMT is an independent risk factor for stroke and myocardial infarction [1-3].

Duplex ultrasonography of the internal carotid arteries (ICAs) is indicated in several clinical settings, including patients who have experienced transient ischemic attacks, patients with ischemic stroke, and asymptomatic patients who possess cervical carotid bruits, and as a preoperative evaluation before coronary artery bypass graft surgery or aortic valve replacement. Background: The optimal duplex ultrasound (DUS) velocity criteria to determine in-stent carotid restenosis are controversial. We previously reported the optimal DUS velocities for >or=30% in-stent restenosis.

Cerebrovascular duplex ultrasound for carotid disease is a powerful tool that has become an invaluable resource in the decision making process. Carotid duplex ultrasound is an accurate noninvasive technique to estimate the risk of atheroembolic stroke using extracranial carotid artery bifurcation−based imaging and velocimetry criteria.

Coverage Policy . Duplex scan to evaluate for carotid artery stenosis is considered medically necessary for ANY of the following indications: Carotid stenosis is a risk factor for ischemic stroke. Imaging for CAS includes duplex ultrasound, CTA, MRA, and catheter angiography, but ultrasound is usually the preferred initial imaging modality. The presence of atherosclerotic plaque in the carotid artery is a predictor for future risk of cardiovascular disease. But when the amount is not severe, the focus is on drug treatment, not surgery. Progression is associated with a number of factors, including diabetes and smoking.

The use of carotid artery ultrasound as a diagnostic tool in the evaluation of syncope can be traced to multiple articles from the 1980s.

Carotid duplex ultrasonography is largely used as a first line diagnostic tool for carotid stenosis in symptomatic and asymptomatic patients.
