Comparison of the carotid ultrasound indexes between advanced age and middle-and-low age patients with acute cerebral infarction

ObjectiveTo investigate the differences of carotid ultrasound indexes between advanced age and middle-and-low age patients with acute cerebral infarction.

MethodsA total of 134 patients with acute cerebral infarction(≥65 years old) were divided into the advanced age group(≥80 years old) and middle-and-low age group(65-79 years old).The differences of the ultrasound indexesincluding intima-media thickening(IMT), number of plaques, plaque position, plaque property and degree of vascular stenosis were compared between two groups.

ResultsThe differences of the number of plaques and IMT between two groups were not statistically significant(P>0.05), the detection rate of plaques at the bifurcation of right carotid artery in advanced age group was significantly higher than that in middle-and-low age group(P < 0.05), and the differences of the plaque property and degree of vascular stenosis between two groups were statistically significant(P < 0.05).

ConclusionsAmong the elderly patients with acute cerebral infarction, the plaque at right carotid artery bifurcation is more common, the unstable plaque is less common, and the degree of vascular stenosis is relatively mild.
