128层螺旋CTA联合彩色多普勒超声在诊断颈动脉狭窄中的应用研究

128-MSCT Angiography Combined with Color Doppler Flow Image in the Assessment of Carotid Artery Stenosis

  • 摘要: 目的:探讨128层螺旋CT血管造影联合彩色多普勒超声(CDFI)在诊断颈动脉狭窄性病变(CAS)中的应用价值。方法:58例颈动脉狭窄患者分别于1周内行128层螺旋CTA及彩色多普勒血管超声检查,共计116个节段,以DSA检查结果为金标准,比较分析MSCTA与CDFI对颈动脉狭窄诊断的结果。结果:MSCTA检出轻度狭窄9支,中度狭窄12支,重度狭窄18支,完全闭塞14支;经CDFI诊断轻度狭窄9支,中度狭窄13支,重度狭窄19支,完全闭塞13支。对颈动脉轻、中、重度狭窄及闭塞的诊断符合率分别为84.6%、79.5%、86.7%、92.8%及82.6%、76.7%、85.1%、91.2%,MSCTA与CDFI对不同程度颈动脉狭窄检查结果一致性极佳(佳2=247.56,ν=17,P<0.001,Kappa=0.872)。结论:MSCTA与CDFI对颈动脉狭窄性病变诊断具有良好的一致性,两者联合可广泛用于颈动脉狭窄性病变的筛查和诊断,为治疗方案的选择提供重要的参考依据,可作为基层医院颈动脉狭窄的重要筛查依据而推广应用。

     

    Abstract: Objective: To assess the value of 128-slice CT angiography(MSCTA) combined with color Doppler flow image in the assessment of carotid artery stenosis(CAS). Methods: fifty-eight patients with extracranial carotid stenosis including 116 segments were examined by MSCTA and CDFI within one week, the results of DSA were used as a golden standard. The results of MSCTA and CDFI were comparatively analyzed. Results: The consistent rates in diagnosis on s light-stenosis, mild-stenosis, moderate-stenosis, severe-stenosis and complete occlusion with MSCTA and CDFI was 84.6%, 79.5%, 86.7%, 92.8% and 82.6%, 76.7%, 85.1%, 91.2. The consistency were excellent between MSCTA and CDFI(χ2= 265.261, ν = 16, P<0.001, Kappa =0.870). Conclusions: MSCTA compared with CDFI had excellent consistency with DSA in diagnosis of carotid artery stenosis. MSCTA unite CDFI can be used early screen in artery stonosis. which can be used as an important basis for carotid stenosis screening in primary hospital.
