摘要
目的：探讨电子束ＣＴ三维血管造影（３Ｄ－ＥＢＣＴＡ）在评价脑动静脉畸形手术前后中的价值与限度。材料和方法：选择１１例不同部位、不同类型的脑动静脉畸形进行术前和术后的３Ｄ－ＥＢＣＴＡ和 ＤＳＡ对照研究，采用最大信号强度投影（ＭＩＰ）和表面遮盖法（ＳＳＤ）进行重建。结果：与ＤＳＡ相比，术前３Ｄ－ＥＢＣＴＡ对瘤巢、供血动脉（来源、数目及形态）和引流静脉的显示率分别为１００％、１００％和８１．８％，术后瘤巢及供血动脉和引流静脉的处理情况显示满意率为１００％。结论：３Ｄ－ＥＢＣＴＡ无创、价廉，是诊断脑动静脉畸形的好方法，在术后随访方面可替代ＤＳＡ，但在术前诊断上尚不能取代ＤＳＡ。
To evaluate the diagnostic value of 3 dimensional electron beam computed tomography angiography (3D-EBCTA) in the diagnosis of pre-and postoperative intracranial arteriovenous malformation. Materials and Methods: Three D-EBCTA and DSA were carried out for 11 cases with intracranial arteriovenous malformation, at different locations and in different grades, pre-and postoperatively. The images were reconstructed with MIP and SSD. Results: Using DSA as a gold standard, all nidi, feeding arteries and drainage veins were demonstrated on pre-operative 3D-EBCTA in 100%, 100% and 81 .8% respectively. Three D-EBCTA also showed nidi, feeding arteries and drainage veins well post-operatively. Conclusion: Three D-EBCTA is an noninvasive, low-cost and helpful modality in evaluation of intracraninal arteriovenous malformation. In many cases 3D-EBCTA can be used to replace routine DSA in postoperative follow up. Before obtaining more experience preoperative DSA cannot be saved on at present.
