Carotid Ultrasound Examinations: Indications Correlated With Abnormal Findings.

08:00 EDT 17th July 2018 | BioPortfolio

Summary of "Carotid Ultrasound Examinations: Indications Correlated With Abnormal Findings."

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 indication and correlated each indication with the finding of carotid artery disease.We found 26.5% of all examinations were abnormal; 17.5% of patients showed internal carotid artery disease; 10.9%, a moderate stenosis; 5.2%, a severe stenosis; and 1.4%, a total occlusion. For each of the 14 individual indications, with 1 exception, carotid ultrasound examination showed a 19.7% or greater chance of an abnormal result and an 11.6% or greater chance of finding a flow-limiting stenosis of an internal carotid artery.Our results validate the collaborative position of the American College of Radiology, the American Institute of Ultrasound in Medicine, the Society for Pediatric Radiology, and the Society of Radiologists in Ultrasound that, overall and for almost all indications they enumerate, carotid ultrasound examinations are a proven and useful procedure for evaluating extracranial carotid artery disease.

Carotid Artery Calcification on Orthopantomograms (CACO Study) - Is it indicative of carotid stenosis?

It is unclear whether incidental carotid artery calcification (CAC) on radiographs has a defined relationship to clinically significant carotid artery stenosis, and therefore risk of stroke. The prima...

Medical and Biotech [MESH] Definitions

Damages to the CAROTID ARTERIES caused either by blunt force or penetrating trauma, such as CRANIOCEREBRAL TRAUMA; THORACIC INJURIES; and NECK INJURIES. Damaged carotid arteries can lead to CAROTID ARTERY THROMBOSIS; CAROTID-CAVERNOUS SINUS FISTULA; pseudoaneurysm formation; and INTERNAL CAROTID ARTERY DISSECTION. (From Am J Forensic Med Pathol 1997, 18:251; J Trauma 1994, 37:473)

Pathological conditions involving the CAROTID ARTERIES, including the common, internal, and external carotid arteries. ATHEROSCLEROSIS and TRAUMA are relatively frequent causes of carotid artery pathology.

Blood clot formation in any part of the CAROTID ARTERIES. This may produce CAROTID STENOSIS or occlusion of the vessel, leading to TRANSIENT ISCHEMIC ATTACK; CEREBRAL INFARCTION; or AMAUROSIS FUGAX.

The two principal arteries supplying the structures of the head and neck. They ascend in the neck, one on each side, and at the level of the upper border of the thyroid cartilage, each divides into two branches, the external (CAROTID ARTERY, EXTERNAL) and internal (CAROTID ARTERY, INTERNAL) carotid arteries.

The splitting of the vessel wall in one or both (left and right) internal carotid arteries (CAROTID ARTERY, INTERNAL). Interstitial hemorrhage into the media of the vessel wall can lead to occlusion of the internal carotid artery and aneurysm formation.
