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 investigate the clinical features of asymptomatic cerebral infarction. Methods Fifty asymptomatic patients with cerebral infarction admitted to Tonghua Central Hospital from January 2010 to December 2013 were selected as the research object. The clinical data including history, CT and MRI were retrospectively analyzed. Imaging findings, treatment and prognosis. Results The group of 45 patients confirmed by CT examination, accounting for 90.0%; CT examination negative and MRI examination found lesions in 5 cases, accounting for 10.0%; CT and MRI showed multiple lesions in 42 cases, are lacunar infarction, The diameter of the lesion was ≤2.0 cm. There were 8 cases of solitary lesion, which were the cerebral infarction of the major lesion. The diameter of the lesion was> 2.0 cm. The shape of the lesion was irregular. There were 42 cases of hypertension, 14 cases of coronary atherosclerotic heart disease, There were 28 cases of hyperlipidemia, 14 cases of diabetes and 4 cases of paroxysmal arrhythmia. The clinical results on the 14th day were ideal. Followed up for 1 to 3 years and developed into 2 cases of symptomatic cerebral infarction. Conclusion Asymptomatic cerebral infarction does not cause definite neurological symptoms, but progress to symptomatic cerebral infarction, should pay attention to brain imaging examination, and actively control the risk factors, timely and relevant treatment.
