| 中文摘要: |
| 短暂性脑缺血发作是指突然发生的神经症状和体症,24 h内恢复正常。以往主要依据临床表现诊断。随着影像学技术的发展应用,发现大多数TIA患者有脑血流动力学异常改变,脑血流动力学异常的持续存在,提示有必要对TIA的本质重新加以认识,对进行及时、准确治疗TIA,改善预后具有重要意义。本文对短暂性脑缺血发作的临床诊断依据、临床表现及其与颈动脉狭窄的关系以及影像学诊断方法等方面进行综述。 |
| 英文摘要: |
| Currently, the definition of transient ischemic attack (TIA) is a sudden onset of neurological symptom that is of vascular etiology and resolve within 24 hours. Its diagnosis depends on clinical manifestations. However, with the development of techniques of imaging, hemodynamic changes were found in transient ischemic attack patients. The presences of hemodynamic changes predict that TIA is not a benign condition and that the risk of subsequent stroke is high. The traditional 24-hour defining limit of TIA has recently been challenged. It is important to evaluate TIA in time for treatment and improving prognosis. This review focuses on the current knowledge of clinical diagnosis and relationship with carotid artery stenosis and radiological diagnosis of TIA. |
