摘　　要：目的:探讨在颈动脉狭窄的诊断中运用血管超声和脑血管造影检查的临床效果。方法:研究纳入某院收治的缺血性脑血管疾病患者85例,研究时间在2018年12月~2019年12月间,依次给予患者血管超声检查和脑血管造影检查,比较两种检查方式在颈动脉狭窄中的诊断效果。结果:在颈总动脉斑块检出率方面,血管超声为51.18%、脑血管造影为52.94%,在颈内动脉斑块检出率方面,血管超声为29.41%、脑血管造影为32.25%,两组对比无明显差异(P>0.05);在狭窄程度的检出率方面,血管超声检查的1级检出率30.59%、2级31.76%、3级15.29%、4级2.94%分别与脑血管造影的1级31.76%、2级33.53%、3级17.06%、4级2.94%相比无明显差异(P>0.05);以脑血管造影的检查结果为金标准,血管超声在颈动脉狭窄诊断方面的敏感性为93.1%、特异性为92%;在狭窄程度的符合率方面1级的符合率为96.3%、2级为94.74%、3级为89.66%、4级为100%。结论:血管超声检查在颈动脉狭窄的诊断中具有较高的敏感性和特异性,在对狭窄程度的判断方面与脑血管造影的检查结果具有高度的一致性,临床应用价值显著。Objective:To investigate the clinical effect of vascular ultrasound and cerebral angiography in the diagnosis of carotid artery stenosis.Methods:A total of 85 patients with ischemic cerebrovascular diseases from December 2018 to December 2019 were studied.The patients were examined by vascular ultrasound and cerebral angiography in turn.The diagnostic effects of the two methods in carotid artery stenosis were compared.Results:The detection rate of common carotid artery plaque was 51.18%by vascular ultrasound and 52.94%by cerebral angiography.In terms of internal carotid artery plaque detection,vascular ultrasound was 29.41%and cerebral angiography was 32.25%.There was no significant difference between the two groups(P>0.05).In terms of the detection rate of the degree of stenosis,the detection rates of grade 1,grade 2,grade 3 and grade 4 by vascular ultrasound were 30.59%,31.76%,15.29%and 2.94%,respectively,and those of cerebral angiography were 31.76%,33.53%,17.06%and 2.94%,respectively,with no significant difference(P>0.05).Taking the results of cerebral angiography as the gold standard,the sensitivity and specificity of vascular ultrasound in the diagnosis of carotid stenosis were 93.1%and 92%,respectively.The coincidence rates of grade 1,grade 2,grade 3 and grade 4 were 96.3%,94.74%,89.66%and 100%,respectively.Conclusion:Vascular ultrasonography has high sensitivity and specificity in the diagnosis of carotid artery stenosis,and it is highly consistent with the results of cerebral angiography in judging the degree of carotid artery stenosis.
