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.
When the plaque does not cause symptoms, people are still at higher risk of stroke than the general population, but not as high as people with symptomatic stenosis. The incidence of stroke, including fatal stroke, is 1–2% per year. The surgical mortality of endarterectomy ranges from 1–2% to as much as 10%.
Coronary endarterectomy involves removing atheroma from the wall of blocked blood vessels (coronary) supplying the heart muscle. The concept was first introduced by Bailey [2] in the 1950s prior to the advent of coronary artery bypass surgery to help patients with angina and coronary artery disease. It is still used today when coronary artery ...
The signs and symptoms of carotid artery dissection may be divided into ischemic and non-ischemic categories: [5] [6] Non-ischemic signs and symptoms: Neck pain and headache, sometimes escalating in intensity [7] Decreased pupil size with drooping of the upper eyelid (Horner syndrome) Pulsatile tinnitus; Ischemic signs and symptoms: Temporary ...
Arteries are blood vessels that carry oxygenated blood to body tissues. [ 1 ] [ 2 ] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia . [ 1 ] Depending on the extent of ischemia, symptoms of arterial occlusion range from simple soreness and pain that can be relieved with rest, [ 3 ] to a lack of sensation ...

Left untreated, this event carries a high risk of stroke; after carotid endarterectomy, which has a low operative risk, there is a very low postoperative stroke rate." [ 43 ] However, the rate of subsequent stroke after amaurosis is significantly less than after a hemispheric TIA, therefore there remains debate as to the precise indications for ...
