短暂脑缺血发作(TIA)是缺血性脑血管疾病的临床表现。近年来,通过临床诊断和治疗等方面的研究,认为当缺血性脑血管疾病处于TIA阶段时,进行适当的治疗,可预防疾病向更严重的阶段发展。本文就近年来文献中关于TIA的致病原因、临床特征、诊断标准、病程及预后、治疗方面的进展作一简要的综述。致病原因致病原因有许多种,现将常见的致病原因分述如下。血管痉挛:是引起TIA的一个重要因素。目前在认识上仍有分歧,为了正确的理解这一问题,必须注意下列事实:1.软脑膜动脉、颈部和韦利氏环的大动脉与穿通动脉和组成微循环的小动脉的反应性很不相同;2.血管痉挛可以是节段性或弥散性;
A transient ischemic attack (TIA) is a clinical manifestation of ischemic cerebrovascular disease. In recent years, through clinical diagnosis and treatment studies, it is considered that when the ischemic cerebrovascular disease is in the TIA stage, proper treatment can prevent the disease from progressing to a more serious stage. This article reviews recent literature on the cause of TIA, clinical features, diagnostic criteria, duration and prognosis, the progress of treatment for a brief review. Pathogenic causes There are many causes of disease, are now common cause of illness are described below. Vasospasm: is an important factor in causing TIA. At present there are still differences in understanding, in order to correctly understand this issue, we must pay attention to the following facts: 1. Palsy, neck and Veely’s ring of the great arteries and perforating arteries and microcirculation of arterioles is very reactive Not the same; 2 vasospasm can be segmental or diffuse;
