数字血管造影三维技术在颅内动脉瘤介入诊疗中的应用

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，28例行GDC栓塞治疗，20例完全致密栓塞，占71．4％。栓塞90％以上8例，占总数的28．5％。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。

The Clinical Application of Three-dimension DSA in the Diagnosis and Embolization Treatment of Intracranial Aneurysms

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.
