摘　　要：目的探讨短暂性脑缺血发作(TIA)患者脑动脉病变的分布特征及其与脑血管高危因素的关系。方法对97例TIA患者行数字减影血管造影(DSA)检查,分析血管病变部位、狭窄程度、受累血管数目的特点及其与脑血管高危因素的相关性。结果89例患者有不同程度的动脉狭窄或闭塞(91.8%),68例存在多血管受累(76.4%);血管病变部位以颈内动脉起始处(35.5%)及椎动脉起始处(28.2%)常见。高危因素越多,受累血管越多、动脉狭窄越重。结论TIA患者脑血管狭窄或闭塞性病变的发生率较高,常为多血管受累,其病变程度与危险因素的多少呈正相关。Objective To evaluate the localization and the correlation with cardiovascular risk factors of cerebral arteries damage in patients with transient ischemic attack （TIA）. Methods Digital subtraction angiography （DSA） was performed in the 97 patients with TIA. The localization, the degree of stenosis, the numbers of the arteries involved and their correlation with the cardiovascular risk factors were analyzed. Results DSA showed occlusive findings of cerebral arteries in 91.8% of the patients, and 68 cases （76.4%） among them were involved more than one artery. The proximal internal carotid arteries （35.5 %） and the proximal vertebral arteries （28.2%） were the most frequently involved in this series. And the number of the arteries involved and the degree of stenosis were positively correlated with the level of risk factors. Conclusion There is a high incidence of cerebrovascular stenosis in patients with TIA. Most of them are involved more than one artery. The degree of the stenosis is positively related with the quantity of the risk factors.
