CDUS and CTA Evaluated the Degree of Carotid Artery Stenosis and the Consistency Analysis of Plaque Morphology and DSA
Objective To explore the consistency of color Doppler ultrasound(CDUS),digital computed tomography angiography(CTA)to evaluate the degree of carotid plaque stenosis and plaque morphology and digital subtraction angiography(DSA).Methods 140 patients with suspected carotid artery stenosis admitted to our hospital from January 2020 to January 2022 were selected as the study subjects.All patients were examined by CDUS,CTA and DSA.Check and compare the degree of carotid artery stenosis and plaque morphology of patients,take DSA examination results as the gold standard,and use Kappa to analyze the efficacy of CDUS and CTA alone and jointly to evaluate the degree of carotid artery stenosis and plaque.Results Among 140 patients suspected of carotid artery stenosis,117 patients were confirmed to have carotid artery stenosis of different degrees by CDUS examination,94 patients were detected by CTA,40 patients were detected by DSA,and the difference between CDUS,CTA and DSA was statistically significant(P<0.05).Through consistency analysis,the sensitivity and specificity of CTA in diagnosing carotid stenosis were higher than those of CDUS,and the specificity and sensitivity of combined diagnosis were higher than those of CTA and CDUS alone.80 plaques were detected in 40 patients with carotid stenosis,and there was no significant difference in the detection rate of irregular plaques among CDUS,CTA and DSA(P>0.05).Through consistency analysis,the sensitivity and specificity of CTA in diagnosing carotid plaque irregularity were higher than those of CDUS,and the specificity and sensitivity of combined diagnosis were higher than those of CTA and CDUS alone.Conclusion Compared with DSA results,CDUS and CTA have certain consistency in detecting the degree of carotid stenosis and plaque morphology,and the combined detection has higher diagnostic value.
