摘　　要：目的探讨三维重建数字减影血管造影(3D-DSA)技术在颅内动脉瘤中的应用。方法使用PHILIPS Allura Xper FD20血管造影机对疑有颅内血管病变的25例患者进行常规DSA和旋转DSA检查,通过遮盖表面显示(Shaded Surface Display,SSD)三维重建方法进行颅内血管重建。结果通过3D-DSA检查24例患者确诊为颅内动脉瘤(26个动脉瘤),1例确认为后交通动脉起始端壶腹样膨大。在3D-DSA检查中25例患者病变血管的位置清晰可见,24例患者26个动脉瘤的形态、瘤颈尺寸、与相邻血管间的关系均可清晰显示或测量。结论3D-DSA技术在颅内动脉造影中可作为一个重要手段,对颅内动脉瘤的诊断与治疗具有重要价值。Objective To evaluate Three-Dimensional Digital subtraction Angiography （3D-DSA）in diagnosis of intracranial aneurysms. Methods Conventional views of DSA and rotational DSA were initially taken in 25 patients suspected with abnormal vasculature using DSA. 3D reconstruction of the intracranial arteries was processed using shaded surface display （SSD） method. Results 24 cases were diagnosed as intracranial aneurysms through 3D-DSA （26 intraeranial aneurysms ）, 1 case was diagnosed as the ampullar enlargement of posterior communicating artery. The precise location of vascular diseases was clearly visualized on 3D-DSA imaging in all 24 cases. The shape of the 26 intracranial aneurysms, their neck size and their relationships to the parent vessels were depicted or measured dearly. Conclusion 3D-DSA is a useful examination supplemented to conventional DSA, which may play an important role in diagnosis and treatment of intracranial aneurysms.
