目的探讨脑白质疏松(LA)与脑血管疾病,尤其是与缺血性脑血管疾病的关系。方法选取我院经MRI检查确诊为脑血管疾病和LA的患者各277例和198例,分析脑血管病患者中不同年龄段LA的发生率、不同类型脑血管病患者中LA的发生率和LA患者中不同类型脑血管病的发生率。结果脑血管患者中LA的发生率随年龄的增长而增加,年龄是LA的独立危险因素,其影响远高于脑血管病对LA发生率的影响;脑出血患者中LA的发生率为30.30%,脑缺血患者中LA的发生率为48.8%;LA患者中发生出血性脑血管病占5.1%,发生缺血性脑血管病占60.1%;47例LA合并腔隙梗塞患者中,基底节梗塞率最高,为63.8%。结论LA的存在可以看作是梗塞发作的预兆,临床上须认识到LA作为中风先兆的重要性。
Objective To investigate the relationship between leukoaraiosis (LA) and cerebrovascular diseases, especially with ischemic cerebrovascular diseases. Methods 277 cases and 198 cases of cerebrovascular disease and LA diagnosed by MRI in our hospital were selected. The incidences of LA in different age groups in patients with cerebrovascular disease were analyzed. The incidence of LA in different types of cerebrovascular diseases and LA The incidence of different types of cerebrovascular disease in patients. Results The incidence of LA increased with age in patients with cerebrovascular disease. Age was an independent risk factor for LA and its effect was much higher than that of cerebrovascular disease. The incidence of LA in patients with cerebral hemorrhage was 30.30% , The incidence of LA was 48.8% in patients with cerebral ischemia, the incidence of hemorrhagic cerebrovascular disease in LA patients was 5.1%, and the incidence of ischemic cerebrovascular disease was 60.1%. Among the 47 LA patients with lacunar infarction, The highest infarction rate was 63.8%. Conclusions The presence of LA can be regarded as a precursor of infarction and the clinical importance of LA as a precursor to stroke should be recognized.
