SUMMARY
Objective: To study the atherosclerotic lesions of carotid artery by measuring the intima
media thickness (IMT), plaque of atherosclerosis and resistance indice (RI) in the patients over
the age of 60 years by using the carotid doppler ultrasonography
Patients and methods: A cross-sectional analysis was conducted among 243 patients
hospitalized at internal medicine department in Hue university hospital. These patients were
divided in 2 groups including (1) group of 40 patients under the age of 60 years and (2) study
group of 203 patients over the age of 60 years
Results: The average of IMT of the left common carotid artery was 1,08 ± 0,47 mm thicker
than that of right CCA (1,03 ± 0,45 mm).The frequence of carotid atherosclerosis was 60,59% of
patients, the average thickness of atherosclerotic plaque was 2,58

1,12 mm, in which the
thickest was 6 mm and the smallest was 0,8 mm.
The prevalence of atherosclerotic plaque in the right CA was 49,25% and in the left CA was
53,69%, in the right bifurcation was 27,59% and the left bifurcation was 30,05%, in the right
CCA was 11,33% and the left CCA was 10,34%, in the right internal CA was 34% and the left
ICA was 13,3% of patients .The average RI of right CA was 0,68 ± 0,07 cm/s and the left CA
was 0,67 ± 0,08 cm/s in the normal value.

of atherosclerotic carotid was 57,29% of stade 0 and 65,79% of stade 3. The carotid IMT in stade
1 were 1,08 ± 0,53 mm and 1,21± 0,55 mm of stade 3.
The thickness of atherosclerotic carotid in stade 0 were 2,34 ± 0,79 mm and 2,32 ± 1,25
mm of stade 3. The prevalence of atherosclerotic carotid in patients with stroke was 63,55%
571
higher than that of non-stroke (57,29%). The carotid IMT in group with stroke was 1,22± 0,55
mm thicker than that of non-Stroke (0,96± 0,30 mm) and the thickness of carotid plaque in group

with stroke 3,00± 1,19 thicker than that of non-stroke (2,07± 0,78 mm).
Conclusions: Athersclerotic carotid lesions (IMT, plaque and RI) in patients over the age of
60 years presented remarcable and could be determined by doppler ultrasonography
Carotid doppler echography revealed atherosclerotic lesions in patient without symtomtology of
cerebral vascular hemodynamic dysfunction (stade 0 of Natali Thevenet clinical classification)
