Objective: To study the correlation between cerebral small vascular disease and constitutiontypes of Traditional Chinese Medicine (TCM). Methods: The severity of lacunar infarction and leukoaraiosis were graded in 230 patients with cerebral small vascular disease, and they were divided into TCM constitution types. The survey of TCM constitution types was carried out by using standardized TCM constitution scale, and order multivariate Logistic regression was used to analyze the correlation between TCM constitution types with severity of lacunar infarction and leukoaraiosis. Results: Yang-deficiency (阳虚) constitution, blood-stasis constitution and phlegm-dampness constitution were the most common TCM constitution types in patients with lacunar infarction, accounting for 33.7％, 12.5％, 11.5％ respectively. Yang-deficiency constitution, blood-stasis constitution and Yin-deficiency (阴虚) constitution were the most common TCM constitution types in patients with leukoaraiosis, accounting for 28.8％,18.5％,13.7％respectively. There were significant differences in lacunar infarction of Yang-deficiency constitution and blood stasis constitution (P<0.05), and there were significant differences in leukoaraiosis of phlegm-dampness constitution and blood-stasis constitution (P<0.05). Single factor analysis showed that the main risk factors of lacunar infarction were age, smoking, alcohol consumption, Yang-deficiency constitution and blood-stasis constitution, and the main risk factors of leukoaraiosis were age, smoking, hypertensive disease, phlegm-dampness constitution and blood-stasis constitution. The ordered multivariate Logistic regression analysis found that the severity of lacunar infarction was closely related to age, and the severity of leukoplosis was closely related to age, smoking and hypertension disease. Conclusion: TCM constitution types of lacunar infarction in patients with small cerebral vascular disease is mainly Yang-deficiency constitution and blood-stasis constitution, and the risk factors include age, smoking, alcohol consumption, Yang-deficiency constitution and blood-stasis constitution. Age is closely related with lacunar infarction. TCM constitution types with leukoaraiosis are mainly phlegm-dampness constitution and blood-stasis constitution, and the risk factors are age, smoking, hypertension disease, phlegm-dampness constitution and blood-stasis constitution. Age, smoking and hypertension disease are closely related with leukoaraiosis.
