    Abstract:
    BACKGROUND: Leukoaraiosis (LA) is an indicator of small vessel disease, but little is known about the relationship between the severity of LA and etiologic subtype of ischemic stroke. Our study aimed to investigate the factors associated with the severity of LA and the relationship between the severity of LA and etiologic subtype of ischemic stroke. METHODS: A total of 791 patients with first-ever ischemic stroke within 7 days were enrolled in our study. We evaluated cranial magnetic resonance imagings including severity of LA in periventricular and deep white matter, severity of silent lacunar infarcts (SLIs), etiologic subtype of ischemic stroke, and topographic patterns of acute cerebral infarcts. Severity of LA was graded as grade 0 when Fazekas scores = 0, grade 1 when Fazekas scores ranged from 1 to 2, and grade 2 when Fazekas scores were greater than or equal to 3. Multivariable ordinal logistic regression was used to analyze the factors associated with the severity of LA. RESULTS: A total of 748 patients (94.6%) had LA, the numbers and proportions of grade 0, grade 1, and grade 2 LA were 43 patients (5.4%), 413 patients (52.2%), and 335 patients (42.4%), respectively. In multivariable ordinal logistic regression analysis, increasing age, higher diastolic blood pressure, admission National Institutes of Health Stroke Scale scores less than or equal to 3, presence of SLIs, and small artery occlusion (SAO) subtype of ischemic stroke were found to be independently associated with higher grade of LA. CONCLUSIONS: LA is prevalent in first-ever ischemic stroke patients. Severe LA is more frequently associated with higher grades of SLIs and ischemic stroke due to SAO.
