摘　　要：目的探讨双能量CTA(DECTA)在颅内动脉瘤夹闭术后随访中的价值。方法对77例临床确诊为颅内动脉瘤并接受动脉瘤钛夹夹闭术的患者行DECTA检查,将原始数据传至后处理工作站进行图像重组,采用原始轴位图像与重建图像相结合的方式进行综合分析。结果 77例中,DECTA均能清晰显示动脉瘤夹闭情况、动脉瘤钛夹及载瘤动脉与其他颅内主要大血管的通畅情况;共84个动脉瘤接受手术夹闭,其中颅内动脉瘤完全夹闭82个,均未发生移位,动脉瘤颈残留2个;3例动脉瘤夹闭术后其他部位出现新发病灶,1例载瘤动脉血管纤细狭窄。结论 DECTA可作为颅内动脉瘤患者动脉瘤钛夹夹闭术后准确、无创的影像学随访方法。Objective To assess the value of dual-energy CT angiography （DECTA） in the follow-up of postoperative in-tracranial aneurysms. Methods Seventy-seven patients diagnosed as intracranial aneurysm and underwent implemented an-eurysm clipping with titanium clips were enrolled. The raw data of CTA were acquired and transmitted to the workstation for image post-processing. Comprehensive analysis and evaluation was made on original axial images and reconstructed ima-ges. Results DECTA of 77 patients was all clearly showed the aneurysm, clips and the patency of parent artery. Among 84 aneurysms, there were 82 aneurysms completely occluded without shifting, 2 with residual aneurysm neck. Among 77 patients, new aneurysms of the other part were detected in 3 patients after clipping, while slight stenosis of aneurysm car rying artery was noticed in 1 patient. Conclusion DECTA can be used as an accurate and noninvasive method for postoper-ative follow-up for patients with aneurysrns after clipping with titanium clips.
