[Need for surgery in asymptomatic carotid stenosis].
1. Asymptomatic carotid stenosis up to 80% do not require prophylactic surgery, but should be followed non-infasively. 2. Stenoses of 80-99% are associated with a significant incidence of stroke which is estimated to be 4-10%/year. 3. Occlusion is considered to be an unfavorable end point, since the risk of stroke remains higher than those with patent arteries. 4. The role of carotid endarterectomy is related to the stroke morbidity and mortality of the procedure. To show significant benefits of surgical therapy during the first two years, it is necessary to have a stroke/death rate of less than 3%.
