摘　　要：目的:探讨颈动脉彩超对脑梗死患者颈动脉狭窄的诊断价值。方法:回顾性选取2021年8月~2023年8月期间于本院就诊的98例脑梗死患者作为研究对象。入院后均行颈动脉彩超及磁共振检查观察颈动脉狭窄情况,以数字剪影全脑血管造影(DSA)检查结果作为“金标准”,比较不同颈动脉狭窄程度患者颈动脉彩超参数[颈总动脉收缩期最大流速(PSV)、舒张末期流速(EDV)]。分析颈动脉彩超参数与颈动脉狭窄程度相关性。比较颈动脉彩超、磁共振对颈动脉狭窄的诊断结果、诊断效能。分析颈动脉彩超、磁共振对颈动脉狭窄程度诊断结果与DSA诊断结果的一致性。结果:不同颈动脉狭窄程度患者PSV、EDV比较:轻度狭窄<中度狭窄<重度狭窄(P<0.05)。PSV、EDV与脑梗死患者颈动脉狭窄程度呈正相关(P<0.05)。98例脑梗死患者中阳性69例,经磁共振检查结果显示,阳性60例。颈动脉彩超对于颈动脉狭窄的诊断灵敏度为94.44(68/72)、准确度为94.90(93/98),高于磁共振检查的灵敏度为80.56(58/72)、准确度83.67(82/98),漏诊为5.56(4/72),低于磁共振检查的19.44(14/72)(P<0.05);颈动脉彩超检查脑梗死患者颈动脉狭窄程度与DSA检查诊断结果一致性Kappa值为0.826,磁共振检查脑梗死患者颈动脉狭窄程度与DSA检查诊断结果一致性Kappa值为0.743。结论:颈动脉彩超对于脑梗死患者颈动脉狭窄具有较高诊断价值。Objective:To explore the diagnostic value of carotid artery color Doppler ultrasound for carotid stenosis in patients with cerebral infarction.Methods:A retrospective study was conducted on 98 patients with cerebral infarction who were treated in our hospital from August 2021 to August 2023.After admission,all patients underwent carotid artery color Doppler ultrasound and magnetic resonance imaging to observe the degree of carotid artery stenosis.The results of digital subtraction angiography(DSA)were used as the"gold standard"to compare the carotid artery color Doppler ultrasound parameters[common carotid artery peak systolic velocity(PSV),end diastolic velocity(EDV)]in patients with different degrees of carotid artery stenosis.Analyze the correlation between carotid artery color Doppler ultrasound parameters and the degree of carotid artery stenosis.Compare the diagnostic results and diagnostic efficacy of carotid artery color Doppler ultrasound and magnetic resonance imaging for carotid artery stenosis.Analyze the consistency between the diagnostic results of carotid artery stenosis using carotid artery color Doppler ultrasound and magnetic resonance imaging and those obtained through DSA.Results:Comparison of PSV and EDV in patients with different degrees of carotid stenosis:mild stenosis<moderate stenosis<severe stenosis(P<0.05).PSV and EDV were positively correlated with the degree of carotid stenosis in patients with cerebral infarction(P<0.05).Out of 98 patients with cerebral infarction,69 tested positive,and 60 of them were confirmed positive by magnetic resonance imaging.The sensitivity and accuracy of carotid artery color Doppler ultrasound for the diagnosis of carotid artery stenosis were 94.44(68/72)and 94.90(93/98),respectively,which were higher than those of magnetic resonance imaging(MRI)with a sensitivity of 80.56(58/72)and an accuracy of 83.67(82/98),with a missed diagnosis rate of 5.56(4/72),which was lower than that of MRI with a missed diagnosis rate of 19.44(14/72)(P<0.05).The consistency Ka
