高龄与中低龄老年急性脑梗死病人的颈动脉超声指标比较

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

摘要

摘要:
目的探讨高龄与中低龄老年急性脑梗死病人的颈动脉超声指标差异。
方法选取年龄≥65岁急性脑梗死病人134例，按年龄分为高龄组（≥80岁）和中低龄组（65~79岁）。分析2组病人超声指标的差异，主要包括内中膜厚度（IMT）、斑块数目、斑块部位、斑块性质以及血管狭窄程度等。
结果2组病人的斑块数目、IMT增厚差异均无统计学意义（P>0.05）；高龄组在右侧颈动脉分叉处斑块检出率高于中低龄组（P < 0.05）；高龄组与中低龄组病人的斑块性质、血管狭窄程度差异均有统计学意义（P < 0.05）。
结论高龄老年急性脑梗死病人右侧颈动脉分叉处斑块较多见，而不稳定斑块较少见，血管狭窄程度较轻。

Abstract:
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.
