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。
Objective: To explore the value of 128-slice spiral CT angiography combined with color Doppler ultrasound (CDFI) in the diagnosis of carotid stenosis (CAS). Methods: Fifty-eight patients with carotid artery stenosis underwent 128-slice spiral CTA and color Doppler ultrasonography in 116 patients in one week. The results of DSA were the gold standard. The diagnosis of carotid stenosis by MSCTA and CDFI the result of. Results: There were 9 mild stenosis, 12 moderate stenosis, 18 severe stenosis and 14 complete occlusion in MSCTA. There were 9 mild stenosis, 13 moderate stenosis, 19 severe stenosis and 13 complete stenosis by CDFI support. The coincidence rates of diagnosis of mild, moderate and severe stenosis and occlusion of carotid artery were 84.6%, 79.5%, 86.7%, 92.8% and 82.6%, 76.7%, 85.1% and 91.2% respectively. The effects of MSCTA and CDFI on carotid artery stenosis The consistency of the test results was excellent (Good 2 = 247.56, ν = 17, P <0.001, Kappa = 0.872). Conclusion: MSCTA and CDFI have good consistency in the diagnosis of carotid stenosis. The combination of the two can be widely used in the screening and diagnosis of carotid stenosis and provide an important reference for the selection of treatment options. Hospital carotid stenosis based on the important screening and promotion.
