摘　　要：目的评价双容积重建技术在显示脑动脉瘤栓塞程度中的应用价值。方法采用西门子Artis Zeego数字血管造影系统对17例动脉瘤致密栓塞患者进行旋转DSA造影,然后进行双容积重建。结果 17例患者中,14例患者动脉瘤有对比剂显影,14例患者瘤体内中部的弹簧圈中有对比剂显影,4例瘤体远端有对比剂显影,14例瘤颈处有对比剂显影,阴性3例。结论在介入手术以及栓塞术后复查的过程中使用双容积重建可以清晰显示出对比剂在弹簧圈中显影的程度以及位置。评价弹簧圈栓塞的效果以及确定后续治疗和手术策略上有着一定的参考价值。Objective To evaluate the double volume reconstruction technique in displaying the embolization extent of cerebral aneurysms. Methods A total of 17 patients showing densely- occluded cerebral aneurysm were examined with rotational digital subtraction angiography, and then double volume reconstruction by using Siemens Artis Zeego digital angiography system was conducted. The results were analyzed. Results Of the 17 patients, contrast visualization of the cerebral aneurysm was found in 14. In 14 patients, the coils within the aneurysmal cavity stood out clearly due to the presence of contrast medium. Opacification of the distal branch of the aneurysm was detected in 4 cases, and aneurismal neck was displayed in 14 cases. Negative finding was seen in 3 cases. Conclusion In interventional management for cerebral aneurysms, the double volume reconstruction technique can clearly display the extent and location of the contrast medium within the coils, which is very useful in evaluating the embolization effectiveness as well as in planning the subsequent therapeutic measures.
