血管造影正常的TIA患者的长期预后难以确定。有些研究报告结局良好,而有些则认为其预后与动脉粥样硬化性TIA相同。本文回顾以前报告的一个研究,分析所有检查正常并进行随访的患者,以评定在随访期间再发TIAs及出现新的心脏或脑症状(包括卒中)的危险因素。本组包括68例血管造影正常的TIA患者,缺血性半球和/或视觉症状在发作后24小时内消失。颈动脉系统TIAs按国家专门委员会的标准确定。经过详细的4条血管检查,无动脉粥样或溃疡的证据,认为血管造影正常。除外有偏头痛病史者。患者均做头颅CT扫描,排除10例扫描异常的患者。排除9例二维回声心动图异常者和6例Holter监测有异常发现 The long-term prognosis of TIA patients with normal angiography is difficult to determine. Some studies have reported good outcomes, while others have concluded that their prognosis is the same as atherosclerotic TIA. This article reviews a previously reported study that examines all patients who have been normalized and followed up to assess the risk factors for recurrence of TIAs and new cardiac or brain symptoms including stroke during follow-up. The group consisted of 68 patients with TIA who had normal angiography and the ischemic hemisphere and / or visual symptoms disappeared within 24 hours of onset. TIAs carotid system according to the national committee to determine the standard. After a detailed 4 vascular examination, no evidence of atherosclerosis or ulceration, angiography is considered normal. Except for migraine history. Patients were skull CT scan, excluding 10 cases of abnormal scanning patients. Excluding 9 cases of two-dimensional echocardiographic abnormalities and 6 cases of Holter monitoring abnormal findings
