    We read with great interest the recent article by Mac Grory et al.1 The authors conducted a comprehensive review on the carotid network as a possible chain factor of cryptogenic embolic stroke, particularly in young patients without risk factors. This condition accounts for approximately 25% of ischemic strokes and has less severe sequelae than other forms of strokes, making the topic of the association of stroke and other diseases interesting to open discussion, in order to intervene and prevent serious recurrent strokes that will lead to irreversible sequelae.1

    The carotid network is defined as a fibromuscular dysplasia of the intima in the carotid arteries, which causes a deficiency in intraluminal filling along the posterior wall of the carotid bulb, this can be observed through imaging such as ultrasound or CT angiography.2 This pathological entity has been reported as a sub diagnostic,2 because it is little known and does not have the epidemiological impact it should have, even more so because most sufferers are asymptomatic.3 Although there are studies that state that this condition occurs more frequently in a population < 55 years (average 45 - 50 years)4, there are cohorts that report cases near 30 years. In addition, another aspect to highlight is that these studies are carried out mainly in developed countries, so the epidemiological distribution of this condition in low- and middle-income countries is not clearly known, who possess genetic characteris...
