RICA: right internal carotid artery; QCA: quantitative comparative analysis; PSV: peak systolic velocity; EDV: end diastolic velocity; EPD: embolic protection device. Note that continuous variables presented as ; DUS plaque type according to Gray-Weale classification (type 1: uniformly unechoic or hypoechoic; type 2: predominantly (>50%) hypoechoic; type 3: predominantly (>50%) hyperechoic; type 4: uniformly hyperechoic; type 5: uniformly echogenic with posterior shadowing (calcified plaque)) [14].
