老年无症状性脑梗死患者危险因素及影像学特征分析

Risk factors and imaging characteristics in elderly patients with asymptomatic cerebral infarction

目的探究老年无症状性脑梗死(ACI)患者危险因素及影像学特征。方法回顾性分析2016年6月~2018年12月在威海市中心医院住院老年缺血性脑血管病患者400例,设置观察组及对照组各200例。对比分析两组危险因素和影像学特征。结果观察组200例患者中MRI发现238个,病灶多位于额颞顶交界区、额叶、枕叶,为椭圆形或不规则片状。相较于对照组,经危险因素分析显示,观察组合并高血脂、高同型半胱氨酸、高血压史的比率显著较高,对比差异有显著性(P<0.05)。结论高血脂、高同型半胱氨酸、高血压可能是老年人ACI的高危因素,头颅MRI是关键的确诊老年ACI的条件之一。

Objective To investigate the risk factors and imaging characteristics in elderly patients with asymptomatic cerebral infarction(ACI).Methods Four hundred elderly patients with ischemic cerebrovascular disease admitted to Weihai Central Hospital from June 2016 to December 2018 were retrospectively analyzed and randomly divided into observation group and control group.Risk factors and imaging characteristics were compared between the two groups.Results Among the 200 patients in the observation group,238 lesions were found through magnetic resonance imaging(MRI),most of which are located in the frontotemporal parietal junction,frontal lobe and the occipital lobe.The lesions are found in oval shape or having irregular patches.The risk factor analysis shows that the rates of hyperlipidemia,homocysteine and hypertension in the observation group is significantly higher than the control group(P<0.05).Conclusion Hyperlipidemia,high homocysteine and hypertension could be high risks causing asymptomatic cerebral infarction in elderly population.Cranial MRI is one of the fundamental methods to diagnose ACI in the elderly and has great clinical application value.
