目的观察CT血管造影（CTA）与数字减影全脑血管造影（DSA）在评价短暂性脑缺血发作（TIA）患者脑血管状况中的差异。方法对74例TIA患者行CTA及DSA检查，观察两种不同检查方法下患者脑血管异常情况。结果颈内动脉系统TIA中，两种检查方法的敏感性和特异性比较，差异无统计学意义（P＞0.05）；椎基底动脉系统TIA中，DSA检查的敏感性和特异性比CTA高（P＜0.05）；两种方法检查血管狭窄程度效果的比较，DSA优于CTA（P＜0.05）；但CTA检查耗时及并发症发生率低于DSA（分别为P＜0.01和P＜0.05），且检查费用明显较DSA低。结论CTA可作为评估颈内动脉系统TIA患者脑血管状况的初筛方法，而椎基底动脉系统TIA患者脑血管状况的评估仍首选DSA。

Objective To observe the differences of computed tomography angiography (CTA) and digital subtraction cerebral angiography (DSA) in the evaluation of cerebrovascular situation of the patients with transient is -chemic attack(TIA).Methods Seventy-four patients with TIA were examined by CTA and DSA , then the differ-ences of results were observed.Results In the internal carotid artery system TIA, there was no statistically signifi-cant difference in the sensitivity and specificity between CTA and DSA (P>0.05);And in the vertebral-basilar ar-tery system TIA, the sensitivity and specificity of DSA was higher than that of CTA ,the difference was statistically sig-nificant(P<0.05);But on the aspect of the degree of vascular stenosis ,DSA was superior to CTA, the difference was statistically significant(P<0.05).Compared with DSA,the consuming time and incidence of complications were lower in CTA(P<0.01 and P<0.05,respectively), and the inspecting cost was lower obviously .Conclusion CTA is a screening method for assessment of cerebral vascular status in the internal carotid artery system TIA , but the DSA is still the best choice in assessment of cerebral vascular the status in the vertebral -basilar artery system TIA.
