carotid stenosis, x-ray, the left artery, carotid stenosis, x-ray, the right artery, arterial tear in internal carotid artery, atherosclerosis of internal carotid artery, arterial plaque build-up, carotid artery surgery, carotid endarterectomy, carotid artery surgery, surgical procedure, restore adequate blood flow, brain, each side, the neck has an artery, the common carotid, each common carotid splits into two branches, the internal branch, brings oxygen-rich blood, brain, external branch, brings blood, face, blockage, the internal carotid artery, reduce blood supply, brain, causing a stroke, internal carotid arteries, become blocked by fat, cholesterol build-up of atherosclerosis, plaque, over time, plaque slowly begins to block the flow of blood, plaque, block the artery enough to cause a stroke, plaque often causes, blood to flow abnormally, leads to a blood clot, a clot, stay, site of narrowing, prevent blood flow to, the smaller arteries it supplies, type of clot, doesn't travel, a thrombus, in other cases, clot, travel, wedge into a smaller vessel, a clot that travels, an embolism, develop a thrombus, in the internal carotid artery, an embolism, smaller blood vessel, experience symptoms blurred vision, slurred speech, weakness, all signs of stroke, by restoring adequate blood flow, internal carotid artery, strokes, prevented, accomplished either by a surgery, endarterectomy, a procedure known, angioplasty, stent placement, traditionally used, the heart, latter procedure is now used on blood vessels, brain, stent placement, alternative to surgery that enlarges the blockage, in the artery, new technique must only be performed, experienced physician, steps the surgeon takes to reduce the risk of stroke, operation, shunting, using a plastic tube to re-route blood flow, brain, eeg monitoring, doing the operation under local anesthetic, talk, surgeon, general anesthesia is used, allows the patient to be unconscious, pain free, treat symptoms of carotid artery blockage, weakness, the arm, leg, face on one side, inability to move the arm, leg, face on one side, paralysis, numbness, tingling, noticeable change, in the sensation, the arm, leg, face on one side, difficulty swallowing, loss of, part of vision, blindness, in one eye, slurred speech, inability to speak, dizziness, vertigo, confusion, fainting, coma, stroke, complete recovery, tia, severe blockage, symptoms at, seek urgent medical attention, experience these symptoms, symptoms permanent, they occur transiently, get better by themselves, tia, transient ischemic attack, still might be a sign of a serious problem, surgery should also be done, carotid artery blockages which cut off between 75-99% of blood flow, major artery, large studies have shown, such severe blockages, no symptoms at, risk of stroke is reduced, surgery, blockage is complete, 100%, surgery, not be performed, the risk of stroke, significant brain damage, procedure is too great, x-ray studies using special dyes, carotid angiogram, degree of blockage, the carotid arteries, studies, visualize blockages, in the carotid arteries, ultrasound, magnetic resonance angiography, mra, risks, anesthesia, reactions to medications, problems breathing, surgery, bleeding, infection, additional risks of carotid surgery, blood clots, brain damage, strokes, 1-3%, in the hands of an experienced surgeon, heart attacks, carotid artery surgery, helps, prevent further brain damage, reduces the risk of stroke, lifestyle changes, diet, exercise, approved by physician, plaque buildup, clot formation, in the carotid arteries, after surgery, observed overnight to watch, signs of bleeding, stroke, compromised blood flow, brain, recent trend to send the patient home the same day, operation, patient is doing well, erratic blood pressure, requiring monitoring in an intensive care unit, relatively common, tends to improve, should not be a cause, concern.
