摘　　要：目的探讨头颈部CT血管造影(CTA)和颈部血管彩超在颈动脉狭窄(CAS)介入治疗中的价值。方法以2022年10月-2023年10月信丰县人民医院拟行介入治疗的48例CAS患者为研究对象,统计其治疗前的数字减影血管造影(DSA)、头颈部CTA、颈部血管彩超检测结果,分析DSA与头颈部CTA、颈部血管彩超的一致性。以DSA为金标准,比较头颈部CTA、颈部血管彩超及两者联合检测对颈动脉狭窄的检出率,比较患者介入治疗前后的头颈部CTA(狭窄远端直径、最小残余直径)、颈部血管彩超参数[收缩期峰值流速(PSV)、舒张期末流速(EDV)]。结果经Kappa检验,头颈部CTA与DSA的检测结果具有较强一致性(k=0.785),颈部血管彩超与DSA的检测结果具有中等一致性(k=0.584)。头颈部CTA联合颈部血管彩超对颈动脉狭窄的检出率高于两者单一检测(P<0.05)。介入治疗后,患者头颈部CTA参数(狭窄远端直径、最小残余直径)大于介入治疗前(P<0.05),颈部血管彩超参数(PSV、EDV)小于介入治疗前(P<0.05)。结论头颈部CTA与颈部血管彩超在CAS检查中具有确切检出作用,二者联合效果更佳,其参数对介入治疗效果具有一定的评估价值。Objective To investigate the value of head and neck CT angiography(CTA)and neck vascular ultrasound in the interventional treatment of carotid artery stenosis(CAS).Methods A total of 48 patients with CAS who underwent interventional therapy in Xinfeng County People's Hospital from October 2022 to October 2023 were selected as the research objects.The results of digital subtraction angiography(DSA),head and neck CTA and neck vascular color Doppler ultrasound before treatment were counted,and the consistency of DSA with head and neck CTA and neck vascular color Doppler ultrasound was analyzed.DSA was used as the gold standard to compare the detection rate of carotid artery stenosis by head and neck CTA,neck vascular color Doppler ultrasound and their combined detection.The head and neck CTA(distal diameter of stenosis,minimum residual diameter)and neck vascular color Doppler ultrasound parameters[peak systolic velocity(PSV),end diastolic velocity(EDV)]before and after interventional therapy were compared.Results By Kappa test,the results of head and neck CTA and DSA had strong consistency(k=0.785),and the results of neck vascular color Doppler ultrasound and DSA had moderate consistency(k=0.584).The detection rate of carotid artery stenosis by head and neck CTA combined with neck vascular color Doppler ultrasound was higher than that by single detection(P<0.05).After interventional therapy,the CTA parameters of head and neck(distal diameter of stenosis,minimum residual diameter)were larger than those before interventional therapy(P<0.05),and the color Doppler ultrasound parameters of neck(PSV,EDV)were smaller than those before interventional therapy(P<0.05).Conclusion Head and neck CTA and neck vascular color Doppler ultrasound have a definite detection effect in CAS examination,and the combined effect of the two is better.The parameters have certain evaluation value for the effect of interventional therapy.
