目的分析短暂性脑缺血发作(transient ischemia attack,TIA)的临床特点和责任血管病变分类。方法通过对数字减影血管造影(digital subtraction angiography,DSA)资料的分析,对68例TIA患者的临床特点和责任血管病变进行探讨。结果 68例患者中的65例有明确的血管性责任病变。结论 DSA检查有助于明确TIA的血管性病因,并对治疗具有指导意义;代偿性缺血在TIA患者的DSA结果中占有一定比例。
Objective To analyze the clinical features and classification of responsible vascular lesions in patients with transient ischemic attack (TIA). Methods Based on the analysis of digital subtraction angiography (DSA) data, 68 patients with TIA were investigated for their clinical features and responsible vascular disease. Results Of the 68 patients, 65 had definite vascular responsibility lesions. Conclusions DSA can help clarify the vascular causes of TIA and provide guidance for the treatment. Compensatory ischemia accounts for a certain proportion of DSA results in TIA patients.
