Abstract：Objective To explore the application value of head and neck CT angiography (CTA),color Doppler flow imaging (CDFI) and transcranial doppler (TCD) in patients with ischemic cerebrovascular diseases before and after interventional therapy.Methods Eighty-seven patients who were treated by endovascular stent plasty in our hospital from January 2014 to February 2016 were enrolled in the study.All the patients received digital subtraction angiography (DSA),CTA,CDFI and TCD examination before and after treatment,then taking DSA examination results as gold standard to evaluate the application value of CTA,CDFI and TCD before and after interventional therapy.Results A total of 883 intracranial and extracranial blood vessels in 87 patients were examined.Taking DSA examination results as gold standard,the accuracy,sensitivity and specificity of CTA before operation were 94.68％,89.27％ and 96.31％,respectively,which by CDFI examination were 95.58％,90.73％ and 97.05％,respectively,moreover,which by TCD were 93.77％,86.83％ and 95.87％,respectivelt,however the accuracy,sensitivity and specificity of CTA after operation were 94.90％,86.21％ and 95.52％,respectively,which by CDFI were 96.15％,91.38％ and 96.48％,respectively,moreover,which by TCD were 94.11％,81.03％ and 95.03％,respectively.The examination results by CTA,CDFI and TCD had satisfactory consistency with those by DSA examination (Kappa ＞ 0.75,P ＞ 0.05).Conclusion The CTA,CDFI and TCD can be regarded as the imaging examination means in preoperative examination and postoperative evaluation for patients with ischemic cerebrovascular diseases.
