“…It may be that because the NF had a small volume, they were less relevant for clinical lesions due to collateral circulation, despite being in eloquent area. Nonetheless, improvement in cerebral perfusion was shown after CAS in publications by Tavares and Caldas and may counterbalance clinical damage resulting from microemboli that occur after CAS [68,88,89].…”

Currently, ischemic cerebral vascular accident (ICVA; stroke) is an illness with a high incidence and a high mortality rate [1,2]. In Brazil, depending on the state of the Brazilian Federation and the period analyzed, cerebrovascular disease is the leading cause of mortality [3]. Moreover, survivors present a continuous risk of developing serious complications [4]. Carotid atherosclerotic disease is the cause of approximately 15 to 20% of cerebrovascular accidents [5]. Carotid stenosis is present in 7% of men and 5% of women aged 65 years or older [6]. In serious cases (>70% stenosis), stenosis is an important cause of ICVA and transient ischemic attack (TIA). The estimated risk of ipsilateral ICVA in 5 years is 4% in the population without carotid stenosis; the risk increases to 18% in patients with asymptomatic stenosis above 75% and reaches 27% in symptomatic patients with stenosis >75% [7]. Several authors have described risk factors associated with carotid atherosclerosis, such as age, smoking, systemic arterial hypertension (SAH), hypercholesterolemia, coronary artery disease, peripheral vascular disease, and male gender [4,8,9]. 2. Treatment of carotid stenosis Treatment options for carotid stenosis include medication or surgery [10-12]. Clinical treatment includes antiplatelet agents and statins associated with the control of risk factors such as arterial hypertension, dyslipidemia, hyperglycemia, diabetes, and smoking [13]. Relevant studies comparing the outcomes of clinical treatment and surgery showed an important
