摘　　要：目的比较颈部血管超声(CDUS)、CT血管造影(CTA)诊断颈动脉狭窄病变的效果。方法选取经数字减影血管造影(DSA)确诊为颈动脉狭窄患者105例,入组患者均接受过CDUS及CTA检查。以DSA检查结果为金标准,比较CDUS、CTA对动脉狭窄程度及斑块特性的检查准确性。结果动脉狭窄程度分级诊断CTA检查结果与DSA检查结果间的正相关性(r=0.972)略高于CDUS检查(r=0.922),CTA检查特异度、灵敏度、准确率略优于CDUS检查,但CDUS、CTA检查结果与DSA检查结果间差异均无统计学意义(P>0.05)。CTA检查对溃疡斑的检出率(95.35%)略高于CDUS检查(86.05%)。结论 CDUS及CTA诊断颈动脉狭窄效能无显著差异,均可在一定情况下替代DSA检查。Objective To compare the effects of cervical vascular ultrasound(color Doppler ultrasonography, CDUS) and CT angiography(CTA) in the diagnosis of carotid stenosis. Methods 105 patients with carotid stenosis confirmed by digital subtraction angiography(DSA) were selected. All patients were given CDUS and CTA. The DSA examination results were used as the gold standard to compare the examination accuracy of CDUS and CTA on arterial stenosis degree and plaque characteristics. Results Artery stenosis degree classification diagnosis of CTA and DSA examination results between the results of the tests positive correlation(r=0.972) slightly higher than the CDUS check(r=0.922), the CTA check specific degrees, sensitivity, accuracy, slightly better than CDUS is checked, but CDUS, CTA and DSA examination examination result difference between the results had no statistical significance(P>0.05). The detection rate of ulcerative plaque by CTA examination(95.35%) was slightly higher than that by CDUS examination(86.05%). Conclusion There is no significant difference in the efficacy of CDUS and CTA in the diagnosis of carotid stenosis, and the two can replace DSA under certain circumstances.
