短暂性脑缺血发作(TIA)是指伴有局部症状的短暂性的脑血液循环障碍,以反复发作的短暂的言语、运动或感觉障碍为其特点。TIA可能是完全卒中的一个先兆,有的短期内多次发作如不及时控制,就可能出现完全卒中,而致不可逆性损害。目前较一致的意见抗凝治疗可以控制TIA发作,减少完全卒中。但对抗凝治疗持续时间意见尚不一致,有的作者认为凡颈动脉之TIA需终身抗凝,椎基底动脉之TIA长期有症状者治疗需一年以上,但也有人反对长期抗凝治疗。另
Transient ischemic attacks (TIA) are transient cerebral blood circulation disorders with localized symptoms characterized by recurrent episodic speech, motor or sensory disturbances. TIA may be a precursor to a complete stroke, and some episodes in the short term if not timely control, there may be a complete stroke, causing irreversible damage. The current consensus is that anticoagulant therapy can control the onset of TIA and reduce total stroke. However, the duration of anticoagulant treatment is not the same opinion, and some authors believe that the carotid artery TIA required lifelong anticoagulation, vertebrobasilar TIA long-term symptomatic treatment for more than one year, but some people object to long-term anticoagulant therapy. another
