| ［摘要］ 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。 |

| ［Abstract］ 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 ischemic attack(TIA).Methods Seventy-four patients with TIA were examined by CTA and DSA, then the differences of results were observed.Results In the internal carotid artery system TIA, there was no statistically significant difference in the sensitivity and specificity between CTA and DSA(P>0.05); And in the vertebral- basilar artery system TIA, the sensitivity and specificity of DSA was higher than that of CTA,the difference was statistically significant(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. |
