Based on the NASCET (The North American Symptomatic Carotid Endarterectomy Trial) criteria, the degree of carotid stenosis is defined as: [22] percent stenosis = ( 1 − ( minimum diameter within stenosis) / ( poststenotic diameter ) ) × 100%. Calculators have been developed to facilitate grading of carotid stenosis per NASCET criteria. [23]
Carotid endarterectomy is used to reduce the risk of strokes caused by carotid artery stenosis over time. Carotid stenosis can either have symptoms (i.e., be symptomatic), or be found by a doctor in the absence of symptoms (asymptomatic) - and the risk-reduction from endarterectomy is greater for symptomatic than asymptomatic patients.
Late complications such as recurrent stenosis may occur, and surveillance with duplex ultrasound or CT-Angiography may be performed. The risk-reduction from intervention for carotid stenosis (stenting or endarterectomy) is greatest when the indication for intervention is symptoms (i.e., the patient is symptomatic) - typically stroke or TIA. [6]
Often considered one of the safest ways to treat symptomatic carotid stenosis, carotid endarterectomy is a procedure by which a surgeon gently removes atherosclerotic plaque. Blood flow hopefully then returns to normal, increasing oxygen concentration to normal amounts in watershed areas of the brain.
The proximal part of left subclavian is blocked (shaded artery). This prevents antegrade ("forward") flow to the left arm and left vertebral. As a result, flow in the left vertebral is retrograde ("backwards") towards the left arm. Flow to the brain and circle of Willis is via antegrade right and left carotid and right vertebral arteries.

The most common of cerebrovascular conditions treated by vascular surgeons is carotid artery stenosis which is a narrowing of the carotid arteries and may be either clinically symptomatic or asymptomatic (silent). Carotid artery stenosis is caused by atherosclerosis whereby the buildup of atheromatous plaque inside the artery causes narrowing ...
Many carotid bruits are discovered incidentally in an otherwise asymptomatic patient. The presence of a carotid bruit alone does not necessarily indicate the presence of stenosis, and the physical examination cannot be used to estimate the degree of stenosis, if present; therefore, any bruit must be evaluated by ultrasound or imaging.
Plaque enhancement on ultrasound has been proven to correlate with neovascularization, inflammation, and inflammation, and these features are associated with symptomatic carotid plaques. [1] Intravenous contrast is able to improve the performance of carotid ultrasound in diagnosing carotid artery stenosis. [2]
