摘要
目的探讨无症状性脑梗死（SCI）的临床特征及其危险因素。方法对56例SCI患者的临床资料、影像学检查、危险因素进行分析。结果SCI好发于50～70岁，临床无神经系统定位体征，临床表现无特异性。病灶直径在0．4～1．6em。腔隙性脑梗死53例（94．64％），大病灶性脑梗死3例（5．36％）；病灶位于内囊26例，基底节15例，放射冠区7例，丘脑3例，脑干2例。危险因素中，高血压、动脉粥样硬化18例（32．14％），糖尿病、高脂血症18例（32．14％），冠心病、心房颤动5例（8．93％）。结论高血压病、动脉粥样硬化、糖尿病、冠心病、高脂血症等均为SCI的危险因素。SCI无明确的神经系统定位体征，确诊依赖于影像学检查。
Objective To explore the clinical characteristics and risk factors of silent cerebral infarction（SCI）. Methods Clinical character, image characteristics and risk factors of 56 patients with SCI were analyzed. Results The most age of SCI was 50 - 70 years old. There was no typical clinical manfestion and focal neurological signs. The diamers of focus were 0.4 - 1.6 cm. Fifty-three cases were lacunar infarction（94.64% ） ,3 cases were macrofocus infarction（5.36% ）. The focuses of twenty-six cases were situated in capsula intema, 15 cases in basal ganglia ,7 cases in corona radiata,3 cases in cerebral ganglion,2 cases in brainstem. Eighteen cases were hypertension and artherosclerosis （ 32. 14% ） , 18 cases were diabetes and hyperlipemia （ 32. 14% ） ,5 cases were coronary heart disease and atrial fibrillation（ 8.93% ）. Conclusion Hypertension, artherosclerosis, diabetics, coronary heart disease and hyperlipidemia are risk factors for SCI. There was no definite focal neurological signs in patients with SCI,final diagnosis of SCI must depend on imageology detection.
