目的探讨多层螺旋CT血管成像(MSCTA)对椎动脉变异的无创性诊断价值。方法本文回顾性分析西南医院用MSCTA诊断的椎动脉变异7例。结果单侧椎动脉缺如1例,椎动脉起始部变异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5例。结论多层螺旋CT血管成像是无创活体状态诊断椎动脉解剖变异较好的方法。
Objective To investigate the value of multislice spiral CT angiography (MSCTA) in the noninvasive diagnosis of vertebral artery variability. Methods In this paper, 7 cases of vertebral artery changes diagnosed by MSCTA in Southwest Hospital were retrospectively analyzed. Results One case of unilateral vertebral artery absent and one case of vertebral artery anomalous. The vertebral artery on one side did not merge into the basilar artery in 5 cases. Conclusion Multi-slice spiral CT angiography is a good method to diagnose the anatomical variation of vertebral artery in noninvasive living condition.
