[摘 要] 目的 探討腦白質疏松(LA)與腦大血管疾病(LVD)在流行
病學危險因素上的異同?
方法 回顧性納入307名腦梗死或TIA的患者,通過頭顱MRI評估LA,血管DS
A評估LVD,同時登記患者血管危險因素?根據頭顱MRI和DSA評估結果將患者分成三組:LA組
,LVD組及對照組?應用單因素和多因素分析探討各個危險因素在三組之間的差異?
結果 性別?年齡?高血壓?糖尿病?同型半胱氨酸(Hcy)?總膽固醇(
TC)?低密度脂蛋白(LDL)?吸煙史?他汀類用藥史在三組患者中分布不全相同(P<0
.05)?年齡?高血壓?Hcy與LA呈正相關(OR=1.12~5.66,P<0.01);年齡?男
性?高血壓?糖尿病與LVD呈正相關(OR=1.08~4.19,P<0.01)?
結論 LA與LVD在病因學上既有相同的危險因素,同時也存在著顯著的差異

[Abstract] Objective To investigate the similarities and diffe
rences of risk factors between leukoaraiosis (LA) and cerebral large vessel dise
ase(LVD).
Methods A total of 307 patients with cerebral infarction or TIA
were included. All patie
nts underwent cranial MRI examinations to assess LA and underwent DSA examinatio
ns to assess LVD. The cerebral vascular risk factors were collected in the mean
time. According to the results, all patients were divided into three groups, LA
group, LVD group and control group. Then a univariate analysis and a binary Lo
gistic regression analysis were used to investigate the similarities and differe
nces of risk factors among the three groups.
Results The distribution of sex, age, hypertension, diabetes mel
litus, Hcy, TC, LDL, smoking and statin usage in three
groups were different (P<0.05). Age [OR=1.15, 95%CI(1.10~1.21)], hy
pertension [OR=5.66, 95%CI(2.38~13.47)], Hcy [OR=1.12, 95%CI(1.05~1.2
0)] were the independent risk factors of LA; age [OR=1.08, 95%CI(1.04~1.21
)], man [OR=3.15, 95%CI(1.59~6.22)], hypertension [OR=2.09, 95%CI(1.08
~4.04)], diabetes mellitus [OR=4.19, 95%CI(1.76~9.99)] were the indepen
dent risk factors of LVD (all P<0.05).
Conclusions LA and LVD have some same risk factors, and there we
re significant differences between the two groups.

腦白質疏松癥(leukoaraiosis,LA)又被稱為腦白質變性,在老年人口的頭顱影像學檢查endprint
中很常見?近來的研究發現LA與卒中?癡呆?抑郁?殘疾?死亡等密切相關?目前對LA
的發病機制?病理生理改變等仍存有諸多不明?普遍認為慢性缺血是其主要原因,病理改變
以小血管為主?LA與腔隙性腦梗死?腦微出血,都歸類于腦小血管疾病(SVD),最新的研究
提示SVD與大血管疾病(LVD)有密切的關聯[1],但LA與LVD之間是否存在相關性仍
有較大爭議?本研究選擇缺血性腦血管疾病的人群,通過對LA和LVD危險因素的分析,進一
步從病因學方面探討兩者的異同?
