【摘要】 目的探讨颈动脉杂音在颈动脉病变中的诊断价值。方法对185例缺血性脑卒中或短暂性脑缺血发作(TIA)的住院患者在住院当日进行颈动脉听诊,随后行颈动脉彩色多普勒超声检查。以颈动脉彩色多普勒超声结果为金标准,将研究对象依据病变轻重分为正常组、内膜增厚组、斑块组、轻度狭窄组、中度狭窄组和重度狭窄组,对数据进行统计学分析。结果颈动脉杂音诊断颈动脉病变、颈动脉斑块、颈动脉狭窄的灵敏度分别为51.4%、58.3%、79.2%;特异度分别为86.6%、73.4%、63.2%;阳性预测值为89.5%、50.8%、13.3%;阴性预测值为44.5%、78.9%、97.7%;诊断比值比(DOR)为6.84、3.86、6.53。结论颈动脉听诊可以作为颈动脉病变尤其是颈动脉斑块及狭窄的初步筛查,但不能替代颈动脉多普勒超声检查。更多还原

【Abstract】 Objective To investigate the diagnostic value of carotid bruits in carotid lesions. Methods A total of 185 inpatients with cerebral ischemic stroke or transient ischemic attack(TIA) underwent bilateral carotid auscultation and then carotid Doppler ultrasound examination. Taking carotid Doppler ultrasound examination as golden standard, the research object according to the severity were divided into normal group, plaque group, mild stenosis group, moderate stenosis group and severe stenosis group. Statistical analysis was performed on data. Results The sensitivity of carotid bruit in diagnosis carotid lesion, carotid plaque, carotid stenosis was 51.4%, 58.3%, 79.2%; The specificity was 86.6%, 73.4%, 63.2%; The positive predictive value was 89.5%, 50.8%, 13.3%; The negative predictive was 44.5%, 78.9%, 97.7%. Diagnostic odds ratio was 6.84, 3.86, 6.53. Conclusion The carotid auscultation can be used as early screening method of carotid lesions, but cannot replace carotid Doppler ultrasound examination.更多还原
