本文为探讨短暂性脑缺血发作(TIA)患者发作间期CT灌注成像(CT perfusion,CTP)变化,为其诊断、治疗提供影像学依据.对69例TIA患者发作间期均行CTP检查,获得脑血流量(cerebral blood flow,CBF)、脑血容量(cerebral blood volume,CBV)、平均通过时间(mean transit time,MTT)、达峰时间(time to peak,TTP)等参数值,左右对比了解患侧脑缺血情况,根据CTP将TIA分期,并分析各参数与TIA症状之间的关系.得出结论:TIA患者发作间期仍有脑灌注异常,患侧CBF/健侧CBF越低提示脑缺血越严重,为TIA的诊断、治疗提供影像学依据。

本文为提高对成人肾病综合症合并脑梗死的临床特点及危险因素的认识.收集了首都医科大学宣武医院神经内科2000年以来明确诊断的成人肾病综合症合并脑梗死的病例,对其临床资料和影像学进行回顾性分析.得出结论:肾病综合症合并脑梗死以颈内动脉系统,尤其大脑中动脉供血区梗死多见,往往合并不同程度的大脑中动脉狭窄。高脂血症,高纤维蛋白血症,低蛋白血症等为肾病综合症合并急性脑梗死的常见危险因素。
