平板3D-DSA在颅内动脉瘤诊断和介入治疗中的价值

目的评估平板探测器三维数字减影血管造影（3D-DSA）技术在颅内动脉瘤诊断和介入治疗中的应用价值。方法对51例蛛网膜下腔出血的患者进行常规全脑血管DSA检查后,再行旋转DSA采集数据,利用工作站进行三维重建。分析3D-DSA与常规DSA对颅内动脉瘤显示的差异,评价3D-DSA对介入栓塞治疗的指导意义。结果常规DSA检出脑动脉瘤34例,经应用旋转DSA及三维重建后检出46例,其中35例进行介入血管内栓塞治疗,栓塞效果良好,11例行手术夹闭治疗。结论3D-DSA可显著提高颅内动脉瘤的检出率,能够直观清楚地显示动脉瘤详细全面的解剖信息,指导制定治疗计划,在脑动脉瘤的诊断和介入治疗中具有重要的价值。

Application of flat panel 3D-angiography in diagnosis and treatment of intracranial aneurysms

Objective To evaluate the value of 3-dimention digital subtraction angiography (3D-DSA) with flat panel detector (FPD) in the diagnosis and treatment of cerebral aneurysms. Methods A total of 51 patients diagnosed as subarachnoid hemorrhage were examined by conventional DSA and rotational DSA. Results Cerebral aneurysms were diagnosed by rotating DSA and 3D-reconstruction in 46 patients, while conventional DSA found cerebral aneurysms only in 34 patients. Then 35 patents underwent successful interventional embolotherapy, 11 patients underwent surgical clipping. Conclusion 3D-DSA can significantly increase the diagnostic accuracy of cerebral aneurysm, and is valuable for diagnosis and interventional embolotherapy of cerebral aneurysms.
