摘　　要：目的　评估脑动脉瘤 (CA)的三维DSA诊断价值及其对栓塞治疗的指导作用。方法2 6例蛛网膜下腔出血 (SAH)的患者先行DSA检查 ,然后应用 3D工作软件进行三维重建处理作出诊断 ,根据后处理图像拟定栓塞治疗方案。结果　三维DSA对CA、多发动脉瘤、微小动脉瘤、子动脉瘤和瘤体穿动脉的检出率略高于DSA检出率 ,但差异无显著意义 (χ2 =3.0 1,P >0 .0 5 )。检出的CA2 0例行栓塞治疗 ,完全栓塞 18例。结论　三维DSA有可能提高自发性SAH的CA检出率 ,清楚显示CA的三维形态和空间关系 。Objective To evaluate the value of three dimensional digital subtraction angiography (3D DSA) on the diagnosis and embolization planning of cerebral aneurysms. Methods DSA and 3D DSA were performed in 26 patients ( aged 9-68 years) suspected to be with cerebral aneurysms. The schemes of embolization were worked out according to the results of 3D DSA. Results Positive rate of 3D DSA in showing aneurysm, multiple aneurysm, micro small aneurysm, son aneurysm, and perforated artery was slightly higher than that of DSA, but there was no significant difference (χ 2=3.01, P >0.05). 100% occlusion was achieved in 18 patients with cerebral aneurysms by using embolization. Conclusion 3D DSA may improve the accuracy in diagnosing SAH and in showing clearly the stereo conformation of aneurysm and the relationship of sac and parent artery. It is helpful in the evaluation and guidance of embolization of cerebral aneurysms.
