Stroke is a disease of great health relevance due to its morbidity and high costs generated. Symptomatology varies from asymptomatic, fugitive amaurosis, Transient Ischemic Attack (TIA) and direct manifestations of stroke. In view of this, prevention would be the best option to reduce costs secondary to morbidity and mortality due to stroke. Carotid endarterectomy (ACE) is the most common preventive procedure. ECA is a surgical technique consolidated 50 years ago. Large studies such as NASCET, VA, ECST, ACAS and ASCT have already analyzed and proven the indications, cost-effectiveness and limitations of the technique. Digital angiography is the gold standard for determining the degree of carotid stenosis, as methods of investigating carotid stenosis and defining the surgical indication of endarterectomy. Because it is an invasive examination, with a risk of major complications (TIA / stroke) of approximately 4%, it has been progressively replaced by tomography (Angio-CT) or resonance angiography (Angio-NMR). At the same time, Doppler ultrasonography (US) is a non-invasive, low-cost method of screening carotid stenosis. With the incessant progress of diagnostic methods, Doppler ultrasonography (US) has proven to be a method of choice for noninvasive evaluation of the carotid arteries. The degree of carotid artery stenosis is largely based on either a peak systolic velocity or final diastolic velocity analysis, or both, of the carotid artery. Doppler scanning in pulsed mode combined with B-mode ultrasound allows the diagnosis of carotid atheromatous lesions (> 70% stenosis), with sensitivity and specificity above 90%. The US adds comparative advantages to the other contrasted methods, since it is a lower cost procedure, it lacks complications and contraindications, it is easy to access, it does not require the use of contrast, it also has information about plaque morphology, stenosis percentage and topography of the carotid bifurcation.
