摘　　要：目的：探讨60岁以上老年人颈动脉粥样硬化和脑白质病变（WML）的相关性。方法回顾性分析2012年4月—2014年3月第三军医大学大坪医院神经内科459例住院患者的临床和影像学资料。患者年龄均≥60岁,均行 MRI 及 CTA 检查。依据 MRI 检查结果将患者分为 WML 组和无WML 组,对患者临床资料进行组间对比；参照 NASCET 标准、依据 CTA 检查结果对患者是否存在颈动脉粥样硬化及其狭窄程度进行评估,并采用 logistic 回归分析患者颈动脉粥样硬化发病率、狭窄程度及斑块性质与 WML 发生的关系。结果与无 WML 组（216例）相比,WML 组（243例）年龄较高,且吸烟、饮酒、高血压、糖尿病、冠心病、血脂异常、高尿酸血症及颈动脉粥样硬化的比例较高（P 值均〈0.05）。 logistic 回归分析显示年龄、吸烟、高血压、糖尿病、血脂异常及颈动脉粥样硬化为 WML的危险因素（P 值均〈0.05）。调整其他危险因素的影响后,颈动脉粥样硬化的狭窄程度和 WML 仍无明显相关性（P 值均〉0.05）。颈动脉钙化斑块、脂质斑块、混合斑块的分布在 WML 组和无 WML组间差异有统计学意义（χ^2=5.041,P 〉0.05）。调整其他危险因素的影响后,脂质斑块与 WML 正相关（P 〈0.05,OR =1.84,95% CI 1.47~2.98）,混合斑块和 WML 无明显相关性（P 〉0.05,OR =1.97,95% CI 0.99~2.97）。结论颈动脉粥样硬化增加 WML 发生的风险。颈动脉狭窄程度与 WML 的发生无明显相关性。颈动脉粥样硬化的斑块性质与 WML 有相关性,脂质斑块是 WML 发生的危险因素。Objective To investigate the association between carotid atherosclerosis and white matter lesions （WML）. Methods A cohort of 459 Chinese Han subjects who were over 60 years old with MRI and CTA examination at the same time from April 2012 to March 2014 in the Department of Neurology of Daping Hospital were enrolled and underwent a retrospective analysis. According to the MRI results, all subjects were divided to WML group and non-WML group. All the patients were evaluated with carotid atherosclerosis refer to the NASCET standard. The clinical data of all the subjects were collected and analyzed. The correlations of the incidence of WML with carotid atherosclerosis, degree of stenosis and plaque character were analyzed by logistic associated factor. Results Compared with the non-WML group （n = 216 ）, WML group （ n = 243 ） had a higher age, and the proportion of smoking, drinking, hypertension, diabetes, coronary heart disease, dyslipidemia, hyperuricemia, carotid atherosclerosis were obviously higher （ all P values 〈 0. 05 ）. Logistic regression analysis showed that age, smoking, hypertension, diabetes, dyslipidemia and carotid atherosclerosis were risk factors for WML （all P values 〈0. 05）. After adjustment for other risk factors, there was still no significant association between the grade of stenosis and WML （all P values 〉 0. 05）. The character of carotid atherosclerosis plaque between WML group and non-WML group was significantly different （χ^2 = 5. 041, P 〉 0. 05）. After adjustwent by risk factors, lipide plague was positive related to WML （P 〈 0. 05, OR = 1. 84, 95% CI 1. 47 - 2. 98）, and there was no significant difference in the distribution of mixed plaque between WML group and non-WML group（P 〉 0. 05, OR = 1. 97, 95% CI 0. 99 - 2. 97）. Conclusions Carotid atherosclerosis increases the＆amp;nbsp;risk of WML. The extent of stenosis is not associated with WML. The carotid atherosclerosis plaque type is associated with WML, lipide plaque increases the risk o
