摘要
目的 探讨老年和非老年脑梗死患者颈动脉结构改变的特点。方法 80例经头颅CT或MRI确诊为脑梗死的患者分为两组,老年组患者年龄>6 0岁,共4 0例,非老年组患者年龄≤6 0岁,共4 0例,同时选择36例健康查体者为对照组;采用超声方法探测3组患者颈动脉内中膜厚度(IMT)、动脉粥样硬化斑块发生率、粥样硬化斑块数;比较了脑梗死组与对照组和老年组与非老年组间各指标的差异。结果 脑梗死组颈动脉IMT、动脉粥样硬化斑块发生率、斑块数均显著高于健康对照组,而老年组较非老年组增高明显。结论 老年脑梗死患者超声检查颈动脉表现为IMT明显增厚、动脉粥样硬化斑块发生率及斑块数量均增高;颈动脉超声检查作为无创伤、方便地检查动脉粥样硬化病变的一个手段,对脑梗死的病变程度评估及治疗起着重要的指导作用。
Objective To investigate the characteristics of the structural change of carotid artery in aged patients with cerebral infarction.Methods 80 patients with cerebral infarction were divided into 2 groups according to age:aged group with age>60 years(40 patints),non-aged group with age≤60 years(40 patients).The intima-media thickness(IMT),the incidence of carotid plaque and the number of carotid plaque were measured by ultrasonography in 80 patients and 36 normal centrels.These parameters were compared among these groups.Results IMT,the incidence of carotid plaque and the number of carotid plaque in patients with acute cerebral infarction were higher than those of normal controls.IMT,the incidencc of carotid plaque and the number of carotid plaque in aged patients were higher than those of non-aged ones.Conclusions IMT,the incidnee of carotid plaque and the number of carotid plaque in aged patients with cerebral infarction were higher than those of non-aged ones,As a no-harm and convenience approach for atherosclerosis,carotid ultrasonography plays an important guiding role on assessment of disease degree and treatment in cerebral infarction.
