The carotid stenosis can be asymptomatic or symptomatic (presented either by transient ischemic attach or ischemic stroke without disabling sequelae). The asymptomatic carotid stenosis has a risk rate of 10% per year to present a clinical vascular event. Doppler ultrasound is the main diagnostic exam. Even though, it is not recommended for general population; it must be performed in the cases of great vascular risk. In the last decades randomized trials were made in order to define the best management of carotid stenosis. Based on these studies, endarterectomy has been recommended for symptomatic carotid stenosis greater than 70%; it is also recommended for asymptomatic stenosis greater than 60%. The surgery risk should be analyzed. If surgery is not recommended, the patients must receive clinical treatment. In asymptomatic stenosis the risk factors must be controled. In the symptomatic stenosis, both risk factors control and antiplatelet drugs must be done.
