自CT扫描应用于脑血管病的诊断以来,已发现不少短暂脑缺血发作(TIA)患者在CT扫描时显示有低密度梗塞灶。这一发现对TIA的传统概念提出了疑义。为了确定TIA症状少于24小时的患者中脑梗塞的发生率,以及脑梗塞呈TIA发作时TIA是否有其特殊的规律性,我们自1985年2月至1987年2月所见57例做了CT检查的TIA患者,分为TIA伴脑梗塞和TIA不伴脑梗塞两组,对两组患者的年龄、性别、伴随的危险因素、临床特征、TIA平均和最长的发作时间和次数,以及症状的总持续时间进行了分析。现报道如下。临床资料
Since the CT scan was used in the diagnosis of cerebrovascular disease, many patients with transient ischemic attack (TIA) have been found to have a low-density infarct on CT scans. This finding raises some questions about the traditional concept of TIA. In order to determine the incidence of cerebral infarction in patients with TIA symptoms less than 24 hours and whether TIA has its own specific pattern during a TIA episode of cerebral infarction, we observed 57 cases from February 1985 to February 1987 TIA patients with CT examination were divided into two groups: TIA with cerebral infarction and TIA without cerebral infarction. The age, gender, associated risk factors, clinical features, average and the longest duration of TIA, The total duration of symptoms was analyzed. Report as follows now. clinical information
