颈部血管超声及DSA对颈动脉狭窄病变检测的准确性对比分析

Comparative analysis of accuracy of cervical vascular ultrasound and DSA in detection of carotid artery stenosis

目的 探讨颈部血管超声及DSA对颈动脉狭窄病变检测的准确性对比。方法 选取2019年1月~2020年12月广东省潮州市中心医院收治的疑似颈动脉狭窄病变患者134例,所有患者均进行颈部血管超声及DSA检测。分析颈部血管超声检查诊断价值性、比较两种诊断方式在狭窄程度中诊断正确率、两种诊断方案在狭窄分级中诊断正确率。结果 颈部血管超声检查诊断概率为81.3%;DSA:134例患者中确诊107例,其中斑块39例(97.5%),轻度34例(97.1%),中度17例(94.4%),重度10例(100.0%),闭塞4例(100.0%),两种诊断方式比较,差异无统计学意义(P>0.05);确诊患者107例,其中1级39例(36.45%),2级26例(24.30%),3级24例(22.43%),4级18例(16.82%),诊断正确率比较,差异无统计学意义(P>0.05)。结论 对颈动脉狭窄病变检测过程当中,颈部血管超声虽然具有一定的效果,但是不能完全代替DSA,临床上应当进一步推广应用。

Objective To explore the comparison of accuracy of cervical vascular ultrasound and DSA in detection of carotid artery stenosis. Methods A total of 134 patients with suspected carotid artery stenosis who were admitted to Chaozhou Central Hospital in Guangdong Province from January 2019 to December 2020 were selected. All patients were treated with the cervical vascular ultrasound and DSA detection. The diagnostic value of cervical vascular ultrasonography was analyzed, and the diagnostic accuracy of the two diagnostic methods in the stenosis degree and the two diagnostic methods in the stenosis grade were compared. Results The diagnostic probability of cervical vascular ultrasonography was 81.3%.Among 134 DSA patients, 107 were confirmed, including 39 patients of plaque(97.5%),34 patients of mild(97.1%),17 patients of moderate(94.4%),10 patients of severe(100.0%),and 4 patients of occlusion(100.0%). No significant differences were observed between the two diagnostic methods(P>0.05). A total of 107 patients were diagnosed, including 39 patients(36.45%) in grade 1, 26 patients(24.30%) in grade 2,24 patients(22.43%)in grade 3 and 18 patients(16.82%) in grade 4, and no statistically significant differences were observed in diagnostic accuracy(P>0.05). Conclusion Although the cervical vascular ultrasound has a certain effect in the detection of carotid artery stenosis,it cannot completely replace DSA,and should be further popularized and applied in clinical practice.
