无症状性脑梗死106例临床分析

目的:分析无症状性脑梗死(SCI)的临床特点。方法:对106例体检行头颅CT或MRI检查发现的SCI患者(病例组)和100例同期体检行头颅CT或MRI检查未发现脑梗死者(对照组)分别行血压、血糖、血脂、心电图、超声心动图、颈动脉超声检查,分析病例组的影像学特点,并比较两组高血压病、糖尿病、冠心病、高脂血症及颈动脉斑块的患病率。结果:SCI以腔隙性脑梗死为主(94.44%),病灶主要分布于基底节52例(49.06%)、放射冠21例(19.81%)和内囊19例(17.92%),多病灶患者64例(60.38%),高于单病灶患者42例(39.62%);病例组高血压病、糖尿病、冠心病、高脂血症及颈动脉斑块患病率明显高于对照组(P<0.05)。结论:头颅CT和MRI检查是SCI的确诊的重要依据之一;高血压病、糖尿病、冠心病、高脂血症及颈动脉斑块是SCI的危险因素。

Objective：To analysis the clinical characteristics of silent cerebral infarction （ SCI ）. Methods： 106 patients which checked- up to head CT or MRI showing SCI were set to the treatment group and 100 patients which checked -up to head CT or MRI showing no abnorma were set to the control group, all pationts were examed blood pressure, blood glucose, blood lipid, e- lectrocardiogram, ultrasound heartbeat graph and carotid artery t^l~r.asound, analysed the imaging characteristics of treatment group, and compared the prevalence rate between the two groups of hypertension, diabetes, coronary heart disease, hyperlipidemia and carotid plaque. Results：the SCI were mainly lacunar cerebral infarction（ 94. 44% ） , Cere- bral infarction location were mainly distribu- ted in the basal ganglia （ 49. 06% ） , corona radiata（ 19. 81% ） and the internal capsule （ 17.92% ）, multiple infarction of patients （60. 38% ）is higher than that of single in- farction patients （ 39. 62% ） ; Comparied two groups, the prevalence rate of SCI group is significantly higher than that of control group in hypertension, diabetes, coronary heart disease, hyperlipidemia and carotid ar- tery plaque （ P 〈 0.05 ）. Conclusion： MRI and CT is one of the important methods for confirmative diagnosis of SCI;The risk fae- tors of SCI ineluded hypertension, diabete, coronary heart disease, hyperlipidemia and carotid artery plaque prevalence.
