摘　　要：目的探讨CT血管成像(CTA)在椎-基底动脉先天变异中的应用价值和临床意义。方法选取1356例患者的CTA资料,回顾性分析椎-基底动脉口径、起源、路径、窗式等变异。结果诊断为椎-基底动脉先天变异398例(29.35%):基底动脉发育不良23例(1.70%),椎动脉发育不良219例(16.15%),单干椎动脉形成基底动脉21例(1.55%),椎动脉起源变异45例(3.32%),椎动脉走行变异156例(11.50%),基底动脉和椎动脉开窗畸形51例(3.76%),永存颈动脉—椎基底动脉吻合5例(0.37%)。结论CT血管成像可以准确、直观地显示各种椎-基底动脉先天变异,特别对评价变异血管与毗邻结构的关系方面具有优势。Objective To investigate the application value and clinical significance of CT angiography(CTA)in congenital variation of vertebrobarsilar artery.Methods The CTA images of 1356 patients were collected.We analysed retrospectively the congenital variation of vertebrobarsilar artery in caliber,origin,path and fenestration.Results 398 patients with congenital variation of vertebrobasilar artery were identified as follows 23 cases(1.70%)with basilar artery hypoplasia,219 cases(16.15%)with vertebral artery hypoplasia,21 cases(1.55%)with basilar artery formed by unilateral vertebral artery,45 cases(3.32%)with origin variation of the vertebral artery,156 cases(11.50%)with path variation of the vertebral artery,51 cases(3.76%)with fenestration variation of vertebral artery and basilar artery,and 5 cases(0.37%)with persistent carotid-basilar artery anastomoses.Conclusion CT angiography can accurately and visually display the congenital variation of vertebrobasilar artery,especially in the evaluation of the relationship between the variant vessels and adjacent structures.
