目的:探讨血管超声与64排螺旋CT血管造影(MSCTA)在评价颈动脉狭窄中的价值。方法68例颅外段颈动脉狭窄患者于1周内分别行血管超声及CTA检查,共计272个节段,以DSA检查结果为金标准,对血管超声与CTA对颈动脉狭窄检出的情况进行比较分析。结果超声和CTA对颈动脉轻度狭窄(<50%)、中度狭窄(50%~69%)、重度狭窄和完全闭塞≥70%的判断符合率分别为83.5%、80.6%、87.5%及79.7%、75.0%、83.3%,超声和CTA对不同程度颈动脉狭窄判断符合率之间无统计学差异(P>0.05)。超声和CTA对共同检出的163条血管狭窄率计算值呈显著线性正相关(P<0.01)。血管超声、CTA诊断颈动脉狭窄≥70%的准确度、敏感度、特异度分别为95.7%、87.5%、95.7%及91.4%、83.3%、94.7%,2种方法判断≥70%颈动脉狭窄的ROC曲线下面积分别为0.945、0.925,差异无统计学意义(P>0.05)。结论血管超声与MSCTA在评估颈动脉血管狭窄程度上具有较好的一致性,能够取代有创性DSA诊断颈动脉的重度狭窄和完全闭塞。

Objective To assess the value of ultrasound(US) and 64-slice CT angiography (MSCTA) in the diagnosis of carotid artery stenosis. Methods Sixty-eight patients with extracranial carotid stenosis including 272 segments were examined by ultrasound and CTA within one week, the results of DSA were used as a golden standard. The results of ultrasound and CTA were comparatively analyzed. Results The consistent rates in diagnosis on mild-stenosis(<50%), moderate-stenosis(50%-69%), severe-stenosis and complete occlusion(≥70%) by US and CTA was 83.5%, 80.6%, 87.5%and 79.7%, 75.0%, 83.3%, there were no significant difference (P>0.05). US and CTA were correlated significantly on calculating the stenosis rate (r=0.833, P<0.01). For assessing≥70%stenosis, ROC analysis showed that the diagnostic accuracy was no significantly difference on US and CTA, the AUC values measured by US and CTA were 0.945, 0.925(Z=0.828, P>0.05). Conclusions US has good agreement with MSCTA in assessing carotid artery stenosis, and may replace invasive DSA diagnosis of severe-stenosis and complete occlusion.
