Carotid stenting there was no significant differences out to four years of follow-up between surgery and carotid stenting when counting all three, but carotid endarterectomy (CEA) has a higher risk of heart attacks and CAS has a higher risk of minor stroke than open surgery. Overall, younger patients (<70 years old) had better outcomes with stenting than with surgery. Patients had fewer heart attacks with stenting, but they did have more minor strokes. There was no difference between surgery or stenting for major (disabling) strokes. Prior to this, several European trials have reported results in symptomatic carotid artery stenosis patients comparing surgery
Carotid sinus unstable, predispose to ischemic strokes and transient ischemic attacks, carotid endarterectomies are frequently done for prophylaxis. The carotid sinus can be oversensitive to manual stimulation, a condition known as carotid sinus hypersensitivity, carotid sinus syndrome or carotid sinus syncope, in which manual stimulation causes large changes in heart rate and/or blood pressure. This classically presents as a patient who has "fainted" (actually a presyncope) on several occasions while shaving, or in some other way coming into contact with their carotid sinus. Carotid sinus syndrome is a temporary loss of consciousness that sometimes accompanies convulsive seizures because of the intensity of
