摘要
目的探讨彩色多普勒超声(CDUS)与电子计算机断层扫描血管造影(CTA)在颈动脉支架植入患者的术前评估应用价值。方法分析49例颈动脉支架植入患者治疗前的CDUS、CTA及数字减影血管造影(DSA)影像资料,以DSA检查为标准,评价CDUS和CTA两种检查方法对不同程度颈动脉狭窄诊断的一致性,并评价两种检查方法对不同性质颈动脉斑块诊断的一致性。结果三种检查结果显示49例患者98支血管均有不同程度的颈动脉狭窄,在中度及重度颈动脉狭窄病例,CDUS和CTA检查与DSA检查一致性较强;但是在轻度颈动脉狭窄病例,CDUS与DSA检出结果一致性不强(Κ=0.621),而CTA与DSA检出结果一致性较强;在颈动脉闭塞病例,CTA与DSA检出结果一致性较低(Κ=0.393),而CDUS与DSA检出结果一致性较强。对不同性质斑块,CDUS与CTA的检查结果一致性较强。结论在颈动脉支架植入术前影像学检查中,CDUS与CTA检查在颈动脉狭窄程度和斑块性质上各具优势,两者结合可提高诊断的符合率。
Objective To investigate the application value of color Doppler ultrasound(CDUS)and computed tomography angiography(CTA)in preoperative evaluation of patients with carotid artery stenting.Methods analysis of 49 patients with carotid artery stenting treatment before the CDUS,CTA and digital subtraction angiography(DSA)image data,on the basis of DSA examination,evaluation of CDUS and CTA two inspection methods for different degree of consistency to the diagnosis of carotid stenosis and evaluate two inspection methods for different properties of carotid plaques in the diagnosis of consistency.Results The results of three kinds of examination showed that 98 vessels of 49 patients had different degrees of carotid artery stenosis.In moderate and severe carotid artery stenosis cases,CDUS and CTA examination were consistent with DSA examination.However,in the patients with mild carotid stenosis,the results of CDUS and DSA were not in good agreement(KP=0.621),while the results of CTA and DSA were in good agreement.In the patients with carotid artery occlusion,the concordant results between CTA and DSA were very low(KP=0.393),while the concordant results between CDUS and DSA were very strong.For different plaques,the results of CDUS and CTA were consistent.Conclusion CDUS and CTA have their own advantages in the degree of carotid stenosis and the nature of plaque in the imaging examination before carotid stenting.The combination of CDUS and CTA can improve the coincidence rate of diagnosis.
