摘要
【目的】研究老年人脑梗死发病与颈动脉粥样硬化的关系。【方法】B超测定脑梗死患者 5 0例及32例对照组颈动脉内膜 -中膜厚度 (intimal mediathickness,IMT)、颈动脉狭窄程度及斑块状况 ,比较和分析有关资料。【结果】脑梗死组和对照组颈动脉粥样斑块的发生率 (% )分别为 80 % (4 0 / 5 0 ) ,明显高于对照组31.3% (10 / 32 ) (P <0 .0 1)。脑梗死组颈总动脉和颈内动脉IMT均值、斑块指数 (PI)均值及狭窄的发生率(% )分别为 0 .99± 0 .0 8、0 .96± 0 .0 7、2 .0 1± 1.0 4、80 ,对照组上述指标依次为 0 .75± 0 .0 5、0 .73± 0 .0 6、0 .4 2± 0 .18、31.3,两组相比差异有极显著性 (P <0 .0 1)。【结论】老年人颈动脉粥样硬化与脑梗死的发病机制有密切关系。
Objectives]To study the relationship between the occurrence of cerebral infarction (CI) and atherosclerosis of carotid arteries in elderly patients.The intimal-media thickness (IMT),constriction extent and plaque index(PI) of common and internal carotid arteries (CCA and ICA) in 50 patients with CI and 32 patients without stroke history (control group) were detected and compared by B-mode and color Doppler ultrasound , their relevant data were analyzed.The occurrence rates of carotid atherosclerotic plaques in CI patients and control group were 80% (40/50) and 31.3% (10/32), respectively (P<0.01) . The averages of IMT,plaque index (PI) and constriction extent of carotid arteries in CI patients and control group were 0.99±0.08,0.96±0.07,2.01±1.04 and 0.75±0.05,0.73±0.06,0.42±0.18, respectively; significant difference existed between both groups(P<0.01).[Conclusion]A close relationship is found between carotid atherosclerosis and occurrence of CI in elderly patients.
