目的探讨多层螺旋CT三维血管成像(MS 3D-CTA)在椎基底动脉延长扩张症(VBD)中的诊断价值.方法对10例VBD患者(病例组)的MS 3D-CTA资料进行回顾性分析.使用GELightspeed pro 16层螺旋CT扣描仪获得原始图像,对所有患者均采用容积重组(VR)和最大密度投影(MIP)技术对图像进行三维重组.选择20名同一时期因怀疑脑血管病变而行MS 3D-CTA检查,脑血管正常者作为对照组,病例组和对照组间比较采用Wilcoxon符号秩和检验.结果 10例VBD病例组中,单纯型4例,骑跨型6例.病例组基底动脉(BA)的长度(B1)、偏移程度(Bc)、高度(Bh)和椎动脉(VA)的长度(V1)、偏移程度(Vc)以及两者的直径(Bw/Vw)分别为30.20、7.10、8.80、23.00、5.95、5.05 mm,与对照组的B1 25.60 mm、Bc 1.20 mm、Bh 1.90 mm、V1 17.55 mm、Vc 2.05 mm、B/Vw3.05 mm分别比较,差异均存在统计学意义(P值均＜0.01).结论 VBD临床表现复杂多样,MS3D-CTA是一种有效的评价椎基底动脉延长扩张症的检查技术.

Objective To evaluate the diagnostic value of multi-slice three-dimensional computed tomographic angiography(MS 3D-CTA)for vertebrobasilar dolichoectasia(VBD).Methods MS 3D-CTA of 10 patients with VBD were retrospectively analysed.Source images were got by GE Lightspeed pro scanner.Volume rendering(VR)and maximum intensity project (MIP) were adopted to reconstruct 3D images in all cases.Twenty patients were selected as the control group by suspected cerebra[vascular diseases and underwent MS 3D-CTA at the same period.Enumeration data between the patient group and the control group was assessed by Wilcoxon.test.Results There were 2 types of 10 cases with VBD,including simple type(n=4)and saddle type(n=6).Compared with the control group of the length of the basilar artery(B 1,25.60 mm),the deviant degree(Bc,1.20 mm),the height(Bh,1.90 am),the length of the vertebral artery (V1,17.55 mm),the deviant degree(Vc,2.05 mm),and the diameter of BA and/or VA (Bw/Vw,3.05 mm),there is significant difference in the B1 30.20 mm,Bc 7.10 mm,Bh 8.80 mm,V1 23.00 mm,Vc 5.95 mm,and Bw/Vw 5.05 mm(P＜0.01,all).Conclusion The clinical performances of VBD is different,MS 3D-CTA is a very effective method for the diagnosis of VBD.
