Abstract:
目的探讨颈部血管彩色多普勒超声(carotidcolordopplerultrasound,CDUS)与数字减影血管造影(digitalsubtractionangiography,DSA)在颈动脉狭窄病变检测中的临床价值。方法收集268例怀疑有颈动脉狭窄病变并同时进行颈部血管彩色多普勒超声及数字减影血管造影检查的患者病例,观察颈部血管彩超对颈动脉血管狭窄及斑块检出的灵敏度、特异度和准确度,并对比分析颈部血管彩超检查与DSA检查结果的一致性。结果以DSA检查为金标准,颈部血管彩超与DSA比较,K=0.362,检出颈内动脉狭窄或闭塞的灵敏度为81.72%,特异度为59.42%,准确度为67.16%,漏诊率为18.28%,误诊率为40.58%,阳性预测值为51.7%,阴性预测值为85.95%(χ2=83.043,P<0.01)。结论CDUS与"金标准"DSA检查对比分析,其一致性强度不理想,在的高危人群的检测中,可有较高的灵敏度,在普通人群的检测中特异性较差,可广泛用于颈动脉狭窄的高危人群的早期筛查,但不能替代DSA检查。
