无症状性脑梗死的临床特征分析

Analysis of Clinical Features of Silent Cerebral Infarction

目的探讨无症状性脑梗死的临床特点。方法选取2010年1月至2O13年12月吉林省通化市中心医院收治的50例无症状性脑梗死患者作为研究对象,回顾性分析其临床资料,包括既往史、CT及磁共振成像（MRI）影像学检查结果、治疗方法和预后。结果该组45例患者经CT检查证实,占90.0%;CT检查结果阴性而MRI检查发现病灶5例,占10.0%;CT及MRI显示为多发性病灶42例,均为腔隙性脑梗死,病灶直径≤2.0 cm;单发性病灶8例,为大病灶脑梗死,病灶直径〉2.0 cm,形态不规则呈片状;合并高血压42例,冠状动脉粥样硬化性心脏病14例,高脂血症28例,糖尿病14例,阵发性心律失常4例;治疗14 d临床结果理想,随访1～3年,发展为症状性脑梗死2例。结论无症状性脑梗死没有引起明确的神经系统症状,但会进展为有症状性脑梗死,应重视颅脑影像学检查,积极控制危险因素,及时进行相关治疗。

Objective To explore the clinical features of asymptomatic cerebral infarction.Methods A total of 2010 January to 2o13 in December in Central Hospital of Tonghua,Jilin Province were 50 cases of asymptomatic cerebral infarction patients as the research object,a retrospective analysis of the clinical data,including past medical history,CT scan and magnetic resonance imaging（MRI） imaging findings,treatment methods and prognosis.Results 14 patients 42 cases,and to examine the results of the group of 45 patients by CT examination confirmed that accounted for 90.0%;CT negative MRI lesions were found in 5 cases（10.0%）.CT and MRI showed multiple lesions in 42 cases were lacunar infarction lesion diameter is less than or equal to 2.0 cm,solitary lesions in 8 cases,for large cerebral infarction lesion,lesion diameter2.0 cm,shape irregular patchy,with hypertension and coronary artery atherosclerosis heart disease,high cholesterol,diabetes history in 14 cases,paroxysmal arrhythmia in 4 cases; treatment 14 days clinical results,followed up for 1～3 years,the development of symptomatic cerebral infarction in 2 cases.Conclusion Silent cerebral infarction does not cause a clear neurological symptoms,but it will progress to symptomatic cerebral infarction, should pay attention to the brain imaging examination,active control of risk factors,timely treatment.
