超声与螺旋CT血管成像对椎动脉起始段狭窄的诊断价值

Value of Ultrasonography and Multislice Spiral CT Angiography in the Diagnosis of Stenosis of Vertebral Artery Origin

目的探讨彩色多普勒超声仪检查和多层螺旋CT血管成像(CT Angiography,CTA)对椎动脉起始段狭窄的诊断价值。方法回顾性分析52例患者依据临床症状均做超声和CTA检查,对椎动脉起始段狭窄程度进行对比分析。结果超声检查椎动脉起始段中、重度狭窄检出率为70.19%(73/104),其中使用高频超声检查出狭窄率为30.13%(22/73),低频超声检查出狭窄率为69.86%(51/73);CTA检查椎动脉起始段中重度狭窄检出率为74.03%(77/104),与超声检查结果相比,两者比较无统计学差异。结论超声与CTA对椎动脉起始段狭窄的检出率具有较高的一致性,且超声高、低频探头联合应用检出率显著提高。

Objective To explore color doppler ultrasound and multislice spiral CT angiography(CTA)of vertebral artery segment stenosis diagnosis value.Methods A retrospective analysis was conducted on52patients on the basis of clinical symptoms who underwent ultrasound and CTA examination.The initial segment degree of stenosis of the vertebral artery were compared.Results The ultrasonic examination of vertebral artery moderately severe stenosis detection rate was70.19%(73/104).In which,the stenosis rate was30.13%(22/73)and69.86%(51/73)detected by high frequency sonography and low frequency ultrasound,respectively.The detection rate of the moderate to severe stenosis at the start of vertebral artery by CTA examination was74.03%(77/104),which was not statistically different with that of ultrasound.Conclusion The detection rate of stenosis of vertebral artery stenosis is higher in the patients with ultrasound and CTA,and the detection rate is significantly improved by the combination of the high and low frequency probe.
