【Abstract】 Objective To evaluate the changes of imaging and risk factor and prevention in 81 patients with silent cerebral infarction.Methods Imagings were obtained and blood pressure, serum glucose and lipids,and EEG were studied in 81 patients,all patients were treated with aspirin combined with nimodipine and followed up more than 1 year.Results The lesions were mainly located in centrunsemiovale (72.4%)and periventricular (20.7%) on imaging .The incidence of SCI was (71.4%) in patients with hypertensions and (33.3%) in patients with diabetes and (22.2%) in patients with cardiac disease. The rate of cerebral infarction was (9.8%) and cerebral hemorrhage was (4.5%)in all patients.Conclusions The main locations of SCI were centrunsemiovale and periventricular. The risk factors of SCI were hypertension, diabetes andcardiac disease.Combination with aspirin and nimodipine can effectively prevent in SCI.更多还原
