摘　　要：目的:探讨64层螺旋CT血管造影(CT angiography,CTA)在颅内动脉瘤患者行开颅夹闭动脉瘤术后随访中的应用价值。方法:收集2009年1—11月泸州医学院附属医院神经外科开颅夹闭动脉瘤患者术后CTA随访病例63例。图像重建后主要观察动脉瘤夹闭与否、有无残留、有无再发动脉瘤、瘤夹位置与数量、瘤夹与周围结构的关系,以判断载瘤动脉与邻近血管的通畅情况,同时观察有无血管痉挛及部位、有无脑积水、有无梗死灶。结果:63例患者共68个动脉瘤,所有病例均能清晰显示瘤夹与载瘤动脉及邻近血管的空间关系、瘤夹的个数、载瘤动脉及邻近血管的通畅情况,脑室、脑实质及脑血管痉挛也显示清楚。结论:64层螺旋CT能准确显示动脉瘤夹闭后颅内血管、脑室、脑实质的情况,提供的信息丰富全面,且操作简捷、价廉、风险低,可作为颅内动脉瘤夹闭术后病例的随访工具。Objective： To investigate the value of 64-slice spiral CT angiography （CTA） in the postoperative follow-up for intracranial aneurysms. Methods： From January 2009 to November 2009, 63 patients with aneurysm were operatived consecu- tively in the Affiliated Hospital of Luzhou Medical College were collected, and the 63 patients were followed-up after opera- tive with CTA using 64-slice helical CTA. Observations were done to judge whether the aneurysm is completely obliterated, whether the parent and distal artery is stenosis, whether the parent artery is occluded, whether there was cerebral infarction, artery vasospasm, hydrocephalus and recurrent aneurysm, the relationship between the parent artery and clips and the quantity and location of clips. Results： Sixty-three patients were confirmed with intracranial aneurysm, including 68 aneurysms. For these cases using 64-slice helical CTA could clearly reveal the occlusion of the aneurysms, the relationship between the par- ent artery and the clips and the quantity and location of aneurysm clips, the parent artery and vicinal artery are occluded, ventricle and brain matter reveal clearly. Conclusion： 64-slice helical CTA can be used as postoperative follow-up tool for the aneurysms treated by titanium clips. And it is convenient, cheap and low risk. It can provide more information.
