CTA与DSA在椎动脉入口狭窄诊断中的对照研究

Comparative study of diagnostic value of CTA and DSA in vertebral artery stenosis

目的:比较128排螺旋CT血管造影(CTA)三维血管成像和数字减影血管造影(DSA)在椎动脉入口狭窄诊断中的临床应用价值。方法:选取2007-01~2013-10在我院神经内科住院的椎-基底动脉供血不足所致的脑梗死患者2 026例。由3名主任及副主任医师对其中临床脑血管病患者786例共924根椎动脉入口分别进行CTA与DSA测量,以近心端和远心端的椎动脉作为参考。结果:CTA能清晰显示所有病例椎动脉的入口;而DSA能明确显示924根血管当中的837根椎动脉入口,另外87根椎动脉入口则显示不清晰。结论:CTA检查对椎动脉入口的显示明显优于DSA,可为椎动脉狭窄患者的诊断与治疗提供直观可靠的影像学依据。

Objective： To compare the diagnostic value of 128--slice spiral CTA and digital subtraction angiography （DSA） in vertebral artery stenosis.Methods： A total of 2 026 cases of patients with cerebral infarction due to vertebral artery admitted from January 2007 to October 2013 were retrospective analyzed.786 cases （924 vertebral artery） with clinical cerebrovascular disease were given DSA and CTA examination by three chief and associate chief physicians, nearly heart end and distal vertebral artery were chosen as a reference. Results： CTA could clearly show in all cases of vertebral artery inflow crossing, DSA examination clearly showed that 924 of the 837 vessels which vertebral artery inflow tract, in addition to 87 vertebral artery opening display was not clear.Conclusion：The show of entrance of vertebral artery of CTA is better than DSA,and CTA can provide direct and reliable imaging basis for the diagnosis and treatment of patients with vertebral artery stenosis.
