The so-called “low-grade” stenoses are largely represented (up to 90%) in observational series of “first examinations”. In these, the progression of the stenosis has been calculated in around 7% of cases. The “uncritical” and “serial” prescription of a one-year follow-up by Color Doppler Ultrasound of a carotid stenosis of less than 50% does not bring clinical benefits in terms of stroke reduction while the effects of the overuse of the method are well known. Defining the timing of the Color Doppler Ultrasound follow-up of carotid stenoses of less than 50% requires individualized assessment of the global cardiovascular risk profile (including achievement of secondary prevention targets and degree of adherence to therapy) and additional plaque characterization (e.g. echogenicity, homogeneity, surface area, temporal progression of the stricture) as well as the clinical history.
