目的:观察CT血管造影技术(CTA)与数字减影脑血管造影技术(DSA)对颈内动脉狭窄检测结果的一致性。方法:选取2015年1月至2016年4月在贵州航天医院接受检查并怀疑存在前循环缺血发作的70例患者,所有患者实施64层螺旋CTA与DSA检查,将不同临床检查方式下得出的结果进行对比,明确2种检查方式的敏感度。结果:CTA检查显示70例患者均存在颈内动脉不同程度狭窄,DSA检查下同样70例患者存在不同程度颈内动脉狭窄,2种临床检查方式敏感度均为100%,差异无统计学意义(P>0.05)。结论:CTA与DSA对颈内动脉狭窄临床结果一致性好,可以替代使用。
Objective: To observe the consistency of CT angiography (CTA) and digital subtraction angiography (DSA) in detection of ICA. Methods: From January 2015 to April 2016, 70 patients with suspected anterior circulation ischemic attack in Guizhou Aerospace Hospital were enrolled. All patients underwent 64-slice spiral CTA and DSA examinations. The results of different clinical examinations The results of the comparison, a clear two kinds of inspection sensitivity. Results: CTA examination showed that 70 patients had different degrees of stenosis of internal carotid artery. The same 70 patients under DSA had different degrees of stenosis of internal carotid artery. The sensitivity of two kinds of clinical examination was 100%, the difference was not statistically significant P> 0.05). Conclusion: The clinical results of CTA and DSA for ICA are consistent and can be used instead.
