DATE OF PROCEDURE: MM/DD/YYYY PROCEDURE PERFORMED: Bilateral carotid ultrasound duplex evaluation. PHYSICIAN: John Doe, MD INDICATION: Transient ischemic attack. FINDINGS: Right carotid system: A 2-dimensional analysis reveals mild atherosclerotic disease identified in the right internal carotid artery.
The main indications for performing carotid ultrasound were carotid bruits, multiple cardiovascular risk factors, and known atherosclerotic disease in other vessel
We retrospectively reviewed the consecutive reports for 3191 carotid ultrasound examinations. We tracked 14 indications to determine how often examinations were requested for each The indications for carotid revascularization and perioperative stroke risk assessment for et al. Role of conventional angiography in evaluation of patients with carotid artery stenosis demonstrated by Doppler ultrasound in general et al. Intraoperative carotid artery duplex scanning in a … Carotid Duplex Ultrasound Ultrasound is a study that uses sound waves to "see" inside your body. A carotid duplex ultrasound is performed to evaluate symptoms including dizziness, loss of memory, stroke, loss of musclecontrol and other symptoms that might result from narrowing or blockage of the vessels (carotid arteries) on either side of your neck. Avoid use of ultrasound for routine surveillance of carotid arteries in the asymptomatic healthy population at any time.
Duplex ultrasound imaging alone or in conjunction with extremity systolic blood pressure measurements provides accurate diagnostic information sufficient to identify technical problems and occlusive lesions that can occur following open Ultrasound assessment of carotid arterial atherosclerotic disease has become the first choice for carotid artery stenosis screening, permitting the evaluation of both the macroscopic appearance of plaques as well as flow characteristics in the carotid artery. Introduction The identification of carotid artery stenosis is the most common indication for cerebrovascular ultrasound. The majority of stenotic lesions occur in the proximal internal carotid artery (ICA); however, other sites of involvement in the carotid system may or may not contribute to significant neurologic events. Up to 30% of all major hemispheric events (stroke,… 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 determine how often examinations were requested for each The indications for carotid revascularization and perioperative stroke risk assessment for et al.
This study will include patients with a 30-69% carotid artery stenosis, and assess and the amount of microembolization by transcranial Doppler ultrasound. Standard contra-indications for MRI (ferromagnetic implants like pacemakers or
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. The scale has 3 categories: minor – 0 to 49% narrowed Computed tomographic (CT) scanning and magnetic resonance imaging (MRI) are useful for evaluating the question of cerebral infarction which may result from carotid artery stenosis.
There are several types of peripheral ultrasound exam, but each uses Some indications for a carotid artery duplex scan include weakness, paralysis or
There is a partially calcific plaque with anareaofhomogeneityintheICA,suggestiveofalargely lipid-laden plaque on the posterior wall. Carotid Duplex Ultrasound Ultrasound is a study that uses sound waves to "see" inside your body. A carotid duplex ultrasound is performed to evaluate symptoms including dizziness, loss of memory, stroke, loss of musclecontrol and other symptoms that might result from narrowing or blockage of the vessels (carotid arteries) on either side of your neck. Renal ultrasonography using duplex technique of a normal adult kidney, with the estimation of the systolic velocity (Vs), the diastolic velocity (Vd), acceleration time (AoAT), systolic acceleration (Ao Accel) and resistive index (RI).
Some early warning signs of a stroke are: weakness, numbness, or tingling on one side of
Carotid duplex is an ultrasound test that shows how well blood is flowing through the carotid arteries. The carotid arteries are located in the neck. They supply blood directly to the brain. 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.

Your doctor will recommend carotid ultrasound if you have transient ischemic attacks (TIAs) or certain types of stroke and may recommend a carotid ultrasound if you have medical conditions that increase the risk of stroke , including: High blood pressure. Background: To curb increasing volumes of diagnostic imaging and costs, reimbursement for carotid duplex ultrasound (CDU) is dependent on "appropriate" indications as documented by International Classification of Diseases (ICD) codes entered by ordering physicians.
