作者通过对比分析,对有症状及无症状的两种腔隙梗塞的本质提出假设。研究对象为100例经临床和CT确诊的腔隙梗塞病人,分别对有无临床症状的两组病人的临床特征、血管危险因素和白质疏松进行非变量和多变量逻辑回归分析。有21例病人CT示有一个或多个无症状性腔隙梗塞,另79例为症状性腔隙梗塞。无症状性腔隙梗塞病人较有症状组(71％:19％)的白质疏松和高血压常见,但经多变量逻辑回归分析后白质疏松缺乏显著的统计学意 The authors compare the analysis, the symptomatic and asymptomatic two types of lacunar infarction in the nature of the hypothesis. The subjects were 100 patients with lacunar infarction diagnosed clinically and CT. Non-variable and multivariate logistic regression analysis were performed on the clinical features, vascular risk factors and leukoaraiosis in two groups of patients with clinical symptoms. Twenty-one patients had one or more asymptomatic lacunar infarcts and another 79 as symptomatic lacunar infarcts. Patients with asymptomatic lacunar infarcts were more common in the symptomatic group (71%: 19%) with white matter loosening and hypertension, but there was a lack of significant statistical significance after multivariate logistic regression analysis
