Carotid artery stenosis for screening for carotid artery stenosis depends on whether someone is experiencing symptoms arising from the stenosis or has risk factors for the development of carotid artery disease. The U.S. Preventive Services Task Force (USPSTF) recommends against routine screening for carotid artery stenosis in those without symptoms. While routine population screening is not advised, the American Heart Association recommends screening for people who don’t have symptoms of carotid stenosis but have been diagnosed with related medical conditions or have risk factors for carotid artery disease. Screening is recommended for people who have: The American Heart Association also recommends screening if
Carotid sinus blood vessels. The aortic arch baroreceptors are innervated by the aortic nerve (Nerve of Cyon), which combines with CN X (vagus nerve) and travels to the NTS. It is a sensitive site of the body because stimulation can drive large-scale reflex effects throughout the body. This can be used therapeutically in treatment of resistant hypertension by baroreflex activation. Physical assault at this point, producing massive baroreflex activation can cause dramatic falls in blood pressure and cerebral ischemia. The carotid sinus often has atherosclerotic plaques because of disturbed hemodynamics (low wall shear stress, flow reversal/recirculation). Since these plaques, if large and
