摘要(Abstract):

目的 :评价三维数字血管造影 (DSA)在颅内动脉瘤诊断和栓塞治疗中的应用价值。方法 :对 34例确诊或疑诊颅内动脉瘤的患者行DSA检查 ,利用 3D工作软件行三维重建后做出诊断 ,并根据处理后的图像拟定栓塞治疗方案。结果 :34例患者行 2D DSA确诊动脉瘤 31例 ,共检查出 32个动脉瘤 ;3D DSA确诊 34例 ,共检查出 36个动脉瘤。 34例动脉瘤患者 ,2 8例行GDC栓塞治疗 ,2 0例完全致密栓塞 ,占 71 4 % ,栓塞 90 %以上 8例 ,占总数的 2 8 5 %。结论 :3D DSA可清楚地显示颅内动脉瘤的三维形态和空间结构 ,对诊断和栓塞颅内动脉瘤具有较高的应用价值。
Objective: To evaluate the significance of three-dimensional digital subtraction angiography (3D-DSA) in the diagnosis and embolization treatment of intracranial aneurysms. Methods: Both DSA and 3D-DSA methods were performed on 34 patients who were suspected to suffer from intracranial aneurysms. The schemes of embolization were worked out based on the check results of 3D-DSA. Results: Of the 34 patients, 31 cases were diagnosed as intracranial aneurysms, and 32 aneurysms were detected with 2D-DSA. However, when 3D-DSA was used, the 34 cases were all diagnosed, and 36 aneurysms were found. 28 patients were treated with GDC embolization, of which, 20 cases were embolized completely (71.4%) and 8 cases embolized 90% of the aneurysms (28.5%). Conclusions: 3D-DSA can clearly show the stereo conformation of aneurysem and the relationship of sac and parent artery. It is good in showing multiple aneurysms, small and micro-small aneurysms and perforate artery. So, it is useful in the diagnosis and embolization treatment of cerebral aneurysms.
