5000 extracranial arteries CDS protocols for the period from 2010 to 2012 were analyzed. The age ranged from 40 to 90 years old (average age — 58,9±0,15 years). Among them there were 2550 men and 2450 women. 4104 patients (82,1%) had no stenotic disease, 445 (8,9%) patients had small, 329 (6,6%) — moderate and 106 (2,1%) patients – significant ICA stenoses. 16 (0,3%) patients had ICA occlusion. CCA IM-thickness of less than 0,1 cm had 29,7% of patients, CCA IMT 0,11-0,14 cm — 50,6%; 0,15-0,19 cm had 16,9% patients, thickness of 0,2-0,24 cm had 2,5% of patients, and more than 0.25 cm CCA IMT had 0.2% of patients. There was revealed a significant positive correlation between the average thickness of CCA IMT and the degree of stenosis of the internal carotid artery (r=0,46; t=6,57; p<0,001).

The comparative economic analysis was performed of rationality of one-and two-stage screening of carotid stenosis in the population based on the calculation of identifying of one patient with this disease. The most feasible from economic point is conducting a two-stage screening: stage 1 — defining of IMT CCA, stage 2 — performing extracranialCDS for patients with CCA IMT of more than 0,14 cm.

Key words: screening, carotid stenosis, «Intima-media»complex.
