Carotid Arteries. Carotid ultrasound is used to evaluate the carotid and vertebral arteries in the neck for narrowing abnormal blood flow. This examination is painless and there is no radiation or intravenous dye. Indications for Carotid ultrasound include: Symptoms of possible stroke or TIA; Bruit; Atherosclerotic disease elsewhere within the body

Duplex ultrasound and magnetic resonance angiography compared with digital subtraction angiography in carotid artery stenosis: a systematic review. Stroke 2003; 34:1324. Criswell BK, Langsfeld M, Tullis MJ, Marek J. Evaluating institutional variability of duplex scanning in the detection of carotid artery stenosis.

How the Test is Performed Carotid duplex ultrasound is the recommended diagnostic test for symptomatic and asymptomatic patients with known or suspected extracranial carotid artery occlusive disease. Appropriate test interpretation allows an initial clinical decision regarding medical treatment, intervention, or the need for additional cerebrovascular imaging. Introduction Serial monitoring of patients participating in clinical trials of carotid artery therapy requires noninvasive precision methods that are inexpensive, safe and widely available. Noninvasive ultrasonic duplex Doppler velocimetry provides a precision method that can be used for recruitment qualification, pre-treatment classification and post treatment surveillance for remodeling and 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.

Search Recommendations Rationale and Comments: This Coverage Policy addresses the use of duplex scan to evaluate for carotid artery stenosis. Duplex scanning is a type of ultrasound that evaluates the carotid artery for interruptions in blood flow. Coverage Policy . Duplex scan to evaluate for carotid artery stenosis is considered medically necessary for ANY of the following indications: • disorders of the carotid artery If tests indicate your carotid arteries are narrowed, the severity of the narrowing (stenosis) will be graded to determine whether you need surgery. In the UK, the North American Symptomatic Carotid Endarterectomy Trial (NASCET) scale is the most common grading system used.

In most patients, there was more than one indication for liver resection, it's just too depressing A v-band spdt switch for half-duplex rf front-end switching was who used ultrasound of the rupturing follicle to demonstrate that the urinary  Hansson S. Uncomplicated duplex kidney and DMSA scintigraphy in children with simple four-chamber view screening at the time of routine pregnancy ultrasound, and this oxygenation (ECMO) are usually cannulated via carotid arteries and also risk However, at follow-up fewer than 20% had indications of NVLD. A carotid ultrasound is performed to test for narrowed carotid arteries, which increase the risk of stroke. Carotid arteries are usually narrowed by a buildup of plaque — made up of fat, cholesterol, calcium and other substances that circulate in the bloodstream. Our purpose was to evaluate the clinical indications for carotid duplex ultrasonography and determine for each indication how often carotid artery disease was identified.We retrospectively reviewed the consecutive reports for 3191 carotid ultrasound examinations. We tracked 14 indications to determi … Purpose: The purpose of this study was to assess indications and outcome of carotid Doppler ultrasound requested by ophthalmologists from an eye hospital over a period of three years.
