被引量:3
摘要
病例1 男,46岁,2005年3月10日10时突发左侧肢体无力,逐渐加重,当天下午2时到同济大学脑血管疾病治疗中心急诊。既往有高血压史2年,否认糖尿病史。入院时血压170/100mmHg,脉搏800次/min,呼吸18次/min,神志清楚,左侧轻度中枢性面神经瘫痪,仲舌居中,左上肢肌力0级,下肢1级,美国国立卫生研究院卒中量表(NIHSS)评分9分。发病后6h行超导型磁共振成像(美国Marconi 1.5T EDGE ECLIPSETM)检查,示右侧枕叶陈旧性梗死,弥散加权成像(DWI)、T1、T2加权成像(T1W1,T2W1)未示脑干异常,见图1a~1c。影像学结果不能解释临床症状。按缺血性脑血管病治疗,
