15769 color duplex scanning (CDS) protocols of the extracranial arteries (8061 men, 7168 women) were analyzed. Stenosis of the internal carotid arteries of various gradations were identified in 27,3% of cases (38,0% men and 15,5% women). 2,4% of patients (3,6 % of men , 0,9% women) had significant stenosis. In all age groups, except those younger than 40 and older than 80 years old, stenosis was significantly more prevalent in men.

Abnormal deformation was detected in 24.5% of cases (20,1% of men, 29,9% of women, p<0,05), hemodynamically significant strain was detected in 2,4% (1,8% of men, 3,1% of women, p<0,05). The prevalence of this disease also increased with age.

Key words: carotid arteries, carotid stenosis, abnormal deformation, dolikhoarteriopathy.
