作为临床上常见的缺血性脑血管疾病之一,短暂性脑缺血发作(TIA,Transient Ischemic Attack)是一种因脑部供血障碍而反复发作的短暂性神经功能缺损。其主要临床特征为发作的短暂性、可逆性、局部性,且不遗留任何神经功能残损症状,因此,它的危险性往往被人们所忽视。近些年来,随着影像学、超声学技术的发展和临床医学的不断研究和进步,人们对TIA的认识得到了很大的提高,且进一步细化了TIA的危险性。本文主要从TIA的概念、发病机制、危险因素、临床表现、诊断与鉴别诊断、治疗等几个方面阐述如下。
As one of the most common clinical ischemic cerebrovascular diseases, Transient Ischemic Attack (TIA) is a transient neurological deficit that recurrently occurs due to brain blood supply disorder. The main clinical features of the attack is transient, reversible, localized, and does not leave any symptoms of neurological damage, therefore, its risk is often overlooked. In recent years, with the development of imaging technology and ultrasound technology and the continuous research and progress of clinical medicine, people’s understanding of TIA has been greatly improved, and the risk of TIA is further refined. This article mainly from the TIA concept, pathogenesis, risk factors, clinical manifestations, diagnosis and differential diagnosis, treatment, and several other aspects described below.
