摘　　要：目的探讨短暂性脑缺血发作(TIA)病人脑梗死的发生率与磁共振的表现以及相关的临床因素。方法对176例TIA病人临床资料与评估进行分析。结果磁共振检查发现有梗死灶101例。其中单发新鲜梗死灶53例,多发新鲜灶26例,新旧灶并存22例。81例有血管病变,52例为颈内系统病变,表现为偏侧肢体无力为主。TIA症状持续时间超过30min及发作次数>3次者脑梗死的发生率较高。接受抗凝治疗和抗血小板治疗预后较好。结论TIA可由多种病因引起,反复多次发作、发作持续时间较长者容易发生脑梗死。Objective To explore cerebral infarction incidence, magnetic resonance image （MRI） manifestation and relative clinical factors in patients （pts） with transient ischemic attack （TIA）. Methods The clinical and MRI data of 176 pts with TIA were analyzed. Results There were 101 pts with cerebral infarction （57.3 % ）53 pts with single fresh infarction focus, 26 pts with multiple fresh infarction loci and 22 pts with fresh complicating old infarction loci by MRI examination. There were 81 pts complicated with vascular lesion （52 cases with internal carotid artery lesion）. The incidence of cerebral infarction was higher in pts with TIA symptom lasted over 30 minutes and the attacked over 3 times. The prognosis in pts who accepted anticoagulant treatment and antiplatelet treatment were better. Conclusion TIA was caused by many factor. There was a high incidence of cerebral infarction in pts with TIA that the attack was over 3 times, or the attack lasted over 30 minutes.
