Clinical guidelines (such as those of the American Heart Association (AHA) [28] and National Institute for Clinical Excellence (NICE) [29]) recommend that all patients with carotid stenosis be given medications to control their vascular risk factors, usually blood pressure lowering medications (if they have hypertension), diabetes medication ...
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.
Led by Brajesh, this study identified that so called “asymptomatic” carotid stenosis actually has a negative impact on cognitive function. [26] The study also introduced a novel 3D ultrasound technique to assess carotid plaque morphology, including its geometry and tissue composition.
Showed carotid endarterectomy was beneficial in symptomatic patients. Two year stroke rate in patients with > 70% carotid stenosis decreased from 26% to 9%. Two year stroke rate in patients with > 50% decreased from 15% to 9%. [42] [43] Asymptomatic Carotid Atherosclerosis Study (ACAS) 1662: Demonstrated benefit in asymptomatic patients with ...
The Society for Vascular Surgery (SVS) an American academic society for vascular surgery. Its mission includes education, research, career development and advocacy. [ 1 ] The SVS is the national organization for more than 6,000 vascular surgeons and other medical professionals involved in the prevention and cure of vascular disease .
Carotid artery stenting is an endovascular procedure where a stent is deployed within the lumen of the carotid artery to treat narrowing of the carotid artery and decrease the risk of stroke. It is used to treat narrowing of the carotid artery in high-risk patients, when carotid endarterectomy is considered too risky.
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.

Carotid ultrasound is a low-cost, noninvasive, and accurate diagnostic imaging modality used to evaluate diseases of the carotid arteries. [2] It is most often used to diagnose carotid artery stenosis, a form of atherosclerosis, and has the capability to assess plaque morphology and characteristics. [1]
