carotid stenosis, x-ray, the left artery, carotid stenosis, x-ray, the right artery, arteries, the brain, stroke secondary to carotid stenosis, group of brain disorders involving loss of brain function due, obstruction of blood flow, brain, related to hardening, the arteries, atherosclerosis, stroke secondary to carotid stenosis occurs, a major portion of one, carotid arteries, arteries, in the neck that supply blood, brain, narrowed, blocked, in atherosclerosis, hardening, the arteries, fatty deposits occur, in the inner lining, the arteries, atherosclerotic plaque, a mass of fatty deposits, blood platelets, develops, plaque, obstruct the artery, a clot, thrombus, site, the plaque, obstruction, blockage, the artery, develops slowly, a piece of atherosclerotic plaque, an embolism, break off, travel to an artery, in the brain, causing obstruction far, site, the plaque, atherosclerotic plaque, does not always lead to stroke, many small blood vessels around the carotid arteries, blood flow gradually decreases, small connections, increase in size, by-pass the obstructed area, collateral circulation, is enough collateral circulation, a totally blocked artery, not cause neurologic deficits, stroke secondary to carotid stenosis, common in older people, underlying atherosclerotic heart disease, diabetes mellitus, stroke secondary to atherosclerosis, radiation therapy, cause carotid stenosis, weakness, total inability to move a body part, numbness, loss of sensation, tingling, abnormal sensations, decreased, lost vision, partial, temporary, language difficulties, aphasia, inability to recognize, identify sensory stimuli, agnosia, loss of memory, loss of coordination, swallowing difficulties, personality changes, mood, emotion changes, urinary incontinence, lack of control over bladder, lack of control over the bowels, consciousness changes, sleepiness, stupor, lethargy, coma, unconsciousness, neurologic, motor, sensory examinations, determine specific neurologic deficits, they often correspond closely, location, the injury, brain, examination, emboli, in the retina, abnormal reflexes, abnormal extent of "normal" reflexes, muscle weakness, decreased sensation, a bruit, an abnormal sound heard, the stethoscope, heard over the carotid arteries, the neck, additional tests, high serum lipids, triglycerides, cholesterol, carotid artery stenosis, complete occlusion showing on, carotid, cerebral angiography, carotid duplex, doppler ultrasound, mri, the head, mra, magnetic resonance angiography, the brain vessels, neck vessels, stroke, additional treatment, anti-hypertensive medication needed to control high blood pressure, medications to control blood cholesterol levels required, carotid endarterectomy, surgical removal of plaque, carotid arteries, prevent new strokes from occurring, more than 70%, the carotid artery occluded, no contraindications, reasons against the surgery, coexisting terminal illness, dementia, stroke, third leading cause of death in developed countries, one-fourth, the sufferers die, the stroke, its complications, one-half have long-term disabilities, one-fourth recover most, all function, stroke, symptoms occur, prevention includes control of risk factors, hypertension, diabetes, heart disease, risk factors, smoking, minimized, preferably, treatment of tia, transient ischemic attack, "warning strokes", prevent some strokes.
