摘　　要：目的：探讨三维数字减影血管造影（3D-DSA）在颅内动脉瘤诊断和治疗中的价值。方法151例自发性蛛网膜下腔出血（SAH）患者、1例头痛患者和1例脑梗死患者分别进行二维数字减影血管造影（2D-DSA）和3D-DSA 检查。结果2D-DSA 检出动脉瘤112例（125枚）,检出率73.2%（112/153）；3D-DSA 检出动脉瘤136例（152枚）,检出率88.9%（136/153）（χ2=12.254,P 〈0.05）。3D-DSA 对动脉瘤体与载瘤血管关系和瘤颈大小的显示率为100%（152/152）,而2D-DSA 为61.6%（77/125）,两者比较有统计学差异（χ2=63.993,P〈0.05）。结论3D-DSA 能够提高颅内动脉瘤诊断的准确率,有助于动脉瘤治疗方案的选择。Objective To explore the clinical value of 3-dimensional digital subtraction angiography（3D-DSA）in the diagnosis and therapy of intracranial aneurysms.Methods 2-dimensional digital subtraction angiography （2D-DSA）and 3D-DSA was performed respectively on 1 53 patients,including 1 5 1 cases with spontaneous subarachnoid hemorrhage （SAH）,1 case with headache and 1 case with cerebral infarction;Meanwhile,to compare the difference in diagnosis of intracranial aneurysms between 2D-DSA and 3D-DSA.Results 1 12 patients（125 pieces）with intracranial aneurysms were detected on 2D-DSA,its detecting rate was 73.2%（1 12/1 53 ）;136 patients（1 52 pieces）with intracranial aneurysms were detected on 3D-DSA,its detecting rate was 88.9%（136/1 53）（χ2 =12.254,P 〈0.05）.The displaying rate of 3D-DSA for the relationship between carrying tumor artery and aneurysms and the necks of aneurysms was 100%（1 52/1 52）,however,the displaying rate of 2D-DSA for that was 61.6%（77/125）（χ2 =63.993,P 〈0.05）. Conclusion 3D-DSA can improved the diagnostic accurate rate of intracranial aneurysms,it is important in chosing the therapeutic regimen.
