    Journal: Nan Fang Yi Ke Da Xue Xue Bao; 2010 Jun; 30(6):1425-7. PubMed ID: 20584696.
    Abstract:
    OBJECTIVE: To analyze the risk factors of cerebral microbleeds (CMBs). METHODS: A total of 113 patients with cerebrovascular diseases underwent examinations of magnetic resonance imaging (MRI) of the brain (including T1WI, T2WI, FLAIR, and SWI) and blood biochemical tests, and the brain regions, number and grades of the CMBs were analyzed. The association between CMBs and the cardiovascular risk factors were analyzed. RESULTS: A The occurrence and grade of CMBs were associated with the patients' age, hypertension, diabetes, lacunar infarction, diastolic blood pressure, systolic blood pressure and high-density lipoprotein (HDL) levels (P<0.05). CMB occurrence was significantly associated with diabetes, hypertension, and lacunar infarction (P<0.05), and its incidence varied significantly between different brain regions (P<0.05). CONCLUSION: Age, hypertension, diabetes, lacunar infarction, diastolic blood pressure, systolic blood pressure, and HDL are all risk factors for CMBs, among which diabetes, hypertension, and lacunar infarction are significant risk factors. CMBs occurs most frequently in the cortex and subcortical region, followed by the basal ganglia, thalamus, and the cerebellum, and most unlikely in the brainstem.
