【摘要】 目的对167例微卒中患者的临床及影像学(头颅CT、MRI)特点进行分析总结。方法回顾分析167例微卒中患者的临床及影像学资料。结果①微卒中发病年龄高峰为60～79岁,其发生率约占卒中病例的15.8%(167/1052),以腔隙性脑梗塞为最多见61.1%(102/167),其次为短暂性脑缺血发作(TIA)36.5%(61/167),脑内出血2.4%(4/167)。②临床表现较隐匿,主要有头痛,头晕,一过性肢体乏力,一过性肢体麻木,晕厥。③伴发的高危因素中,以高血压为最多见。且较高比例的患者存在血沉增高和C反应蛋白指数增高。④经CT、MRI检查发现143例(85.6%)可见病灶,部位以基底节区最多见,病灶直径多以小于10mm为主。结论微卒中的临床症状相对较轻,起病形式隐袭。炎症反应可能是微卒中的危险因素之一。微卒中病灶多位于基底节区。更多还原

【Abstract】 Objective To investigate clinical manifestation and image features(CT、MRI) of minor stroke. Methods To review the clinical data of 167 patients of minor stroke retrospectively. Results(1) The incidence of minor stroke is about 15.8%,which includes lacunar infart 61.1%(102/167),TIA 36.5%(61/167),intracerebral hemorrhage 2.4%(4/167).(2) The manifestations mostly consist of headache,dizziness,transient limb-weakness,transient numbness,syncope.(3) In the companying diseases,hypertension is the most common seen. The minor-stroke patients showed a higher frequency of abnormal levels of erythrocyte sedimentation and c reactive protein.(4) 143 cases were found to have lesions which mostly located in the area of basal ganglia with the diameter less than 10mm. Conclusion Minor stroke has relatively slight manifestations which make it likely to be neglect. There is a relationship between inflammatory markers and minor-stroke. CT and MRI serve as valuable supplementary approaches in the diagnosis.更多还原
