摘　　要：目的研究多层螺旋CT血管成像(MSCTA)对椎动脉变异的诊断价值,并探讨其临床意义。方法回顾性分析MSCTA诊断的椎动脉变异32例。结果椎动脉起源变异7例,椎动脉行径变异(进入第5、4或第3横突孔)22例,单侧椎动脉先天性狭窄15例,椎动脉颈段双分支1例,椎动脉窗式变异1例,一侧椎动脉未汇合入基底动脉即单干椎动脉形成基底动脉2例。结论MSCTA是一种无创性诊断椎动脉变异的影像学检查方法。Objective To evaluate the diagnostic value of 16-shce spiral computed tomography angiography （MSCTA） in evaluation of anomalous vertebral artery. Methods MSCTA data from 32 patients with anomalous vertebral artery were retrospectively analyzed. Results 22 cases had vertebral artery course variation（bended into the C5, C4 or C3 foramen transversarium）, 7 cases had variation in the prevertebral segments of vertebral arteries, 15 patients had unilateral vertebral congenital stenosis, 1 case had double vertebral artery branch, 1 case had vertebral arterial fenestration, and 2 cases had vertebral artery in one side that did not converged upon basilar artery and unilateral vertebral artery formed basilar artery. Conclusion MSCTA is a useful noninvasive imaging tool for the diagnosis of vertebral artery variations.
