Objective: To examine native carotid artery without stenosis and carotid artery after endarterectomy (CEA) without restenosis by Color-coded Duplex Ultrasound (CDU) in men, to compare the ultrasound findings and derive ultrasound criteria for postoperative follow-up.

Materials and Methods: We have followed-up two groups of patients: first group - 40 men, mean aged 66,8 years who had CEA mean 2,1 years. Second – group of controls – 40 men, mean aged 68,3 years without cerebrovascular desease. We have evaluated the diameter of the arteries (mm) (common carotid artery (CCA), bifurcation of the CCA (CCAbif), distal internal carotid artery (ICAdist); beginning, center and end of the patch), the peak systolic (PSV) and the end diastolic (EDV) velocities (cm/s) at the same points by using CDU.
