摘要 目的探讨三维CT血管成像(3D-CTA)在颅内动脉瘤诊治中的价值。方法回顾性分析自发性蛛网膜下腔出血(SAH)患者136例。其中,行3D-CTA检查107例,行DSA检查53例,同时行DSA及3D-CTA检查24例。对比3D-CTA和DSA的诊断敏感度、特异度及其图像。结果136例中,确诊动脉瘤103例。3D-CTA的敏感度为97.4%,特异度为100%;DSA的敏感度为95.0%,特异度为100%,两者诊断效能比较,差异无统计学意义(P>0.05)。在显示瘤颈形态、宽度、载瘤动脉及瘤周骨性解剖标志等方面,3D-CTA明显优于DSA。结论3D-CTA能独立诊断颅内动脉瘤,对动脉瘤的形态可提供比DSA更为详尽的资料,给手术提供更多帮助。
