目的:比较血管超声与64排螺旋CT血管造影(CTA)对颈动脉狭窄的诊断价值。方法:选取2014年12月到2015年12月我院收治的疑似颈动脉狭窄患者70例(278节段),所有患者入院1周内均行血管超声、64排螺旋CTA检查,以数字减影血管造影(DSA)为金标准,比较血管超声与64排螺旋CTA对颈动脉狭窄诊断的符合率、特异度和灵敏度。结果:血管超声和64排螺旋CTA对不同程度颈动脉狭窄诊断的符合率比较,差异均无统计学意义(P>0.05);血管超声和64排螺旋CTA对颈动脉狭窄诊断的灵敏度和特异度分别为87.28%、85.71%和85.55%、90.48%,比较差异无统计学意义(P>0.05)。结论:血管超声和64排螺旋CTA对颈动脉狭窄均具有较高的诊断价值。
Objective: To compare the diagnostic value of vascular ultrasound and 64-slice spiral CT angiography (CTA) in the diagnosis of carotid artery stenosis. Methods: Seventy patients (278 segments) with suspected carotid stenosis admitted to our hospital from December 2014 to December 2015 were enrolled in this study. All patients underwent ultrasound and 64-slice spiral CTA within one week after admission. Angiography (DSA) was the gold standard, comparing the coincidence rate, specificity and sensitivity of vascular ultrasound and 64-slice spiral CTA in the diagnosis of carotid artery stenosis. Results: The coincidence rates of vascular ultrasound and 64-slice spiral CTA in diagnosis of carotid stenosis were not significantly different (P> 0.05). The sensitivity and specificity of vascular ultrasound and 64-slice spiral CTA in the diagnosis of carotid artery stenosis Respectively, 87.28%, 85.71% and 85.55%, 90.48%, the difference was not statistically significant (P> 0.05). Conclusion: Vascular ultrasound and 64-slice spiral CTA have high diagnostic value for carotid artery stenosis.
