摘　　要：目的探讨椎基底动脉扩张延长症(VBD)合并脑梗死MRI特征与脑白质疏松症(LA)的相关性。方法收集脑梗死且符合Smoker诊断标准的VBD患者的临床及MRI资料,应用Fazekas视觉模拟评分法对Flair像评分,将LA分为无、轻度、中度、重度4组,比较4组间临床及MRI差异。结果LA严重程度与基底动脉(BA)直径、偏移度、VBD分型差异具有统计学意义(P<0.05);与双侧椎动脉直径差值、BA分叉高度、年龄、高血压、糖尿病、高血脂、吸烟、饮酒差异无统计学意义(P>0.05);BA直径、偏移程度、VBD分型与LA严重程度具有相关性,而分叉高度、双侧椎动脉直径差值无相关性。结论脑梗死合并VBD BA直径、偏移度及VBD分型可能是影响脑白质疏松严重程度的危险因素。Objective To investigate the correlation between MRI features of vertebrobasilar dolichoectasia(VBD)complicated with cerebral infarction and of leukoaraiosis(LA).Methods The clinical and MRI data of VBD patients with cerebral infarction who met the diagnostic criteria of Smoker was collected.FLAIR images were scored by Fazekas visual analog score.LA was divided into four groups:none,mild,moderate and severe.The clinical and MRI differences among the four groups were compared.Results There was statistically significant difference in the severity of LA from basilar artery(BA)diameter,offset and VBD classification(P<0.05),but not from the diameter difference of bilateral vertebral arteries,BA bifurcation height,age,hypertension,diabetes,hyperlipidemia,smoking and drinking(P>0.05).The severity of LA was correlated with the diameter of basilar artery,offset degree and VBD classification,but not with the bifurcation height or the diameter difference of bilateral vertebral arteries.Conclusion The diameter of BA,offset and VBD classification of the patients with VBD complicated with cerebral infarction may be the risk factors affecting the severity of leukoaraiosis.
