摘　　要：目的:分析经颅多普勒超声联合颈动脉超声检查在缺血性卒中诊断中的效能。方法:选取2022年6月至2023年6月该院收治的100例疑似缺血性卒中患者进行前瞻性研究,均进行经颅多普勒超声、颈动脉超声、数字减影血管造影检查,以数字减影血管造影检查结果为金标准,比较颈动脉超声、经颅多普勒超声单项及联合检查在缺血性卒中诊断中的效能。结果:100例疑似缺血性卒中患者中,数字减影血管造影检查确诊阳性70例,阴性30例;颈动脉超声检查确诊阳性63例,阴性37例;经颅多普勒超声检查确诊阳性65例,阴性35例;经颅多普勒超声联合颈动脉超声检查确诊阳性68例,阴性32例;经颅多普勒超声联合颈动脉超声检查诊断缺血性卒中的灵敏度、准确度、阴性预测值均高于二者单项检查,漏诊率低于二者单项检查,差异有统计学意义(P<0.05)。结论:经颅多普勒超声联合颈动脉超声检查诊断缺血性卒中的效能高于二者单项检查。Objective:To analyze efficiency of transcranial Doppler ultrasound combined with carotid ultrasound in diagnosis of ischemic stroke.Methods:A prospective study was conducted on 100 patients with suspected ischemic stroke admitted to the hospital from June 2022 to June 2023.Transcranial Doppler ultrasound,carotid ultrasound and digital subtraction angiography were performed in all patients.Using the results of digital subtraction angiography as the gold standard,the efficiencies of carotid ultrasound,transcranial Doppler ultrasound single and combined examinations in the diagnosis of ischemic stroke were compared.Results:Among the 100 patients with suspected ischemic stroke,70 cases were diagnosed as positive and 30 cases were negative by digital subtraction angiography.Carotid ultrasound confirmed 63 positive cases and 37 negative cases.Transcranial Doppler ultrasound confirmed 65 positive cases and 35 negative cases.Transcranial Doppler ultrasound combined with carotid ultrasound confirmed 68 positive cases and 32 negative cases.The sensitivity,the accuracy and the negative predictive value of transcranial Doppler ultrasound combined with carotid ultrasound in the diagnosis of ischemic stroke were higher than those of the two single examinations,the missed diagnosis rate was lower than that of the two single examinations,and the differences were statistically significant(P<0.05).Conclusions:The efficiency of transcranial Doppler ultrasound combined with carotid ultrasound in the diagnosis of ischemic stroke is higher than that of the two single examinations.
