Results
The presence of calcification of the carotid arteries in 98% of patients of the Group I and only in 57.5% of the Group II.
Localization calcified plaques in all cases consistent with the bifurcation of the common carotid artery and proximal segment of the internal carotid artery.
Defeat carotid arteries on both sides in the Group I noted in 92.2% of patients,
while in Group II was determined by a bilateral lesion in 74.7% of patients.
CS of the carotid arteries was 249.4 [96.5; 659.7] (Me [Q25%; Q75%]) in Group I,
113.9 [44.5; 300.8] – in Group II,
p<0.05 (Fig.1).
The volume of calcium deposits in carotid arteries on MSCT in the GroupI was 232.1 [85.6; 574.2] mm3,
in the Group II – 96.6 [38.3; 270.9] mm3,
p<0.05.
For additional assessment of the atherosclerotic plaque we used the calculated parameter ECDD,
which indicates the characteristics of calcification density.
The values obtained were reproducible.
It has been tested by repeated calculation ECDD by independent radiologist.
ECDD in diabetic patients was significantly lower: Group I – 0.183 [0.17; 0.193] mg/mm3; Group II – 0.226 [0,199; 0,247] mg/mm3,
p<0.05 (Fig.2).
ECDD in patients of Group I did not correlate with CS (r=-0.03,
p>0.05),
and was significantly associated in patients of Group II (r=0.51,
p<0.05).
