3D-DSA技术在诊断颅内动脉瘤中的应用价值

目的:评价3D-DSA技术在颅内动脉瘤诊断中的应用价值。方法:回顾15例蛛网膜下腔出血患者应用传统DSA及3D-DSA进行检查,对比不同方法对动脉瘤的显示情况。结果:所有患者均确诊为颅内动脉瘤,其中常规DSA能确诊12例,3例可疑动脉瘤,常规DSA中只有7例能清楚显示瘤颈形态及载瘤动脉与瘤体的关系。所有病例中3D-DSA均匀清楚显示动脉瘤形态及瘤体与载瘤动脉关系,特别对3例可疑小动脉瘤的显示明显优于常规DSA。结论:3D-DSA技术对颅内动脉瘤病变显示佳,能提高对颅内动脉瘤的诊断水平.

Application of 3D DSA in Diagnosis of Intracranial Aneurysm

Objective To evaluate the application of 3D DSA in diagnosis of intracranial aneurysm. Methods Conventional DSA and 3D DSA were performed in 15 cases with subarachnoid hemorrhage. Results Of 15 cases, by 3D DSA, 12 ones were diagnosed as intracranial aneurysm, and the remaining 3 ones were suspected, while 7 ones could be diagnosed by conventional DSA. Conclusion 3D DSA can improve the diagnosis of intracranial aneurysm.
