Acute stroke represents a major problem in health and is a major cause of disability worldwide. Atherosclerotic carotid stenosis or occlusion causes around 20% of cerebrovascular ischemias.¹ Stroke in patients with carotid stenosis occurs, in most cases, due to embolisms of thrombus formed in the plaque, acute thrombotic occlusion due to rupture of the plaque, or secondary to hemodynamic alterations, attributable to stenosis, which produces decreased cerebral perfusion by low flow, in cases of critical or sub occlusive stenosis. The treatment of carotid disease has evolved considerably over recent years. There are two invasive treatments for significant carotid stenosis, which consist of the surgical approach with endarterectomy or percutaneous treatment with angioplasty and stenting. In our institution, in the period between March 2013 and June 2017, ~100 carotid angioplasties with stent placement were performed. All were assessed with color Doppler ultrasound (DUS) at month, six months and one year (in non complicated cases). In this literature review it is our intention to develop the indications, applications, normal and pathological findings in the DUS examination in the evaluation of a patient with carotid stent.
