1982年Kirino发现短暂性脑缺血在海马回CA_1区有非常慢性的神经元改变,称之为“迟发性神经元死亡”.此后,脑缺血伴迟发性神经病理学变化引起了广泛注意.本研究的目的是分析在局部脑缺血时,远距离非缺血区的神经病理学改变,尤其是大脑中动脉(MCA)分布区梗塞时同侧丘脑的改变.作者5年间收集了109例脑梗塞.根据下列条件选择33例,1.首次发作脑卒中≤2天者;2.初次或追踪脑CT MCA区有单一低密度区;3.追踪对称性丘脑CT扫描1年以上;4.CT显示的无症状复发脑卒中.依据卒中后1月、3月、6月,1年和2年丘脑CT影像,使用计算机化的数字转换器,随机测量患者每侧
In 1982, Kirino found that transient ischemic attacks have a very chronic neuronal change in the hippocampal CA1 region called “delayed neuronal death.” Since then, cerebral ischemia with delayed neuropathological changes has caused The purpose of this study was to analyze the neuropathological changes in long-term, non-ischemic regions during focal cerebral ischemia, especially in the ipsilateral thalamus during infarction in the middle cerebral artery (MCA) 109 cases of cerebral infarction.According to the following conditions were selected in 33 cases, 1. First episode stroke ≤ 2 days; 2. Initial or follow-up brain CT MCA area with a single low-density area; 3. Tracing symmetrical thalamic CT scan more than 1 year; 4. Asymptomatic Recurrent Stroke Indicated by CT Based on CT images of thalamus at 1 month, 3 months, 6 months, 1 year, and 2 years after stroke, a computerized digitizer was used to measure randomly each side of the patient
