摘要(Abstract)：

目的探讨高分辨C臂CT技术联合三维DSA血管成像(3D-DSA)双容积重建融合技术在颅内动脉瘤国产血流导向装置(Tubrige Flow Diverter,Tubrige FD)置入术贴壁评估中的应用价值。方法回顾性分析2019-01—2019-04郑州大学第一附属医院放射介入科连续收治的39例颅内动脉瘤采用Tubridge FD治疗患者的临床及影像学资料,使用西门子DSA后处理工作站将术中FD置入区域20s高分辨C臂CT(Dyna micro CT)扫描结果和5s3D-DSA血管成像结果进行双容积重建并融合,融合图像采用多种后处理技术(如高级三维容积漫游-VRT,最大密度投影-MIP等)动态观察支架贴壁情况,并与载瘤动脉内注射稀释对比剂后20sDyna micro CT扫描重建图像对比,评估前者在判断FD贴壁方面的准确性。结果 39例动脉瘤患者共置入39枚Tubridge FD,其中10例患者联合弹簧圈填塞治疗。在支架贴壁方面,二种技术各自独立检出8例患者FD贴壁不良,31例贴壁良好,一致率100%,其中贴壁不良8例患者采用"massage"技术,即微导丝成袢支架内促使贴壁或球囊扩张处理后支架贴壁良好。结论高分辨C臂CT技术联合3D-DSA双容积重建融合技术能清晰展示Tubridge FD贴壁情况并指导术者采取相应的治疗策略,这种新颖的成像技术在颅内动脉瘤FD置入中具有较大应用前景。
