摘　　要：目的分析经颅多普勒超声联合颈动脉超声诊断缺血性脑卒中的灵敏性及特异性。方法回顾性分析2019年6月—2020年6月于巨野县人民医院就诊的87例疑似缺血性脑卒中患者的经颅多普勒超声及颈动脉超声临床检查资料,对比分析单一经颅多普勒超声及单一颈动脉超声与经颅多普勒超声联合颈动脉超声检查的诊断结果、诊断效能的差异性,并以病理结果为金标准,分析经颅多普勒超声联合颈动脉超声诊断不同闭塞程度血管的灵敏性。结果87例疑似缺血性脑卒中患者行经颅多普勒超声检查显示阳性为73例,阴性为14例;行颈动脉超声检查显示阳性为72例,阴性为15例;行联合超声检查显示阳性为75例,阴性为12例。经颅多普勒超声联合颈动脉超声检查的准确性94.25%高于经颅多普勒超声的准确性80.46%及颈动脉超声的准确性79.31%,差异有统计学意义(χ^(2)=7.493、8.467,P<0.05),特异性81.82%高于经颅多普勒超声的特异性36.36%及颈动脉超声的特异性36.36%,差异有统计学意义(χ^(2)=4.701、4.701,P<0.05),灵敏性96.05%高于经颅多普勒超声的灵敏性86.84%及颈动脉超声的灵敏性85.53%,差异有统计学意义(χ^(2)=4.122、5.035,P<0.05),经颅多普勒联合颈动脉超声检查血管病变的总灵敏性为92.98%。结论经颅多普勒超声联合颈动脉超声应用于缺血性脑卒中的诊断,相较于单一应用经颅多普勒超声或颈动脉超声具较高灵敏性及特异性,可为临床后续治疗开展提供参考依据。Objective To analyze the sensitivity and specificity of transcranial Doppler ultrasonography combined with carotid artery ultrasonography in the diagnosis of ischemic stroke.Methods A retrospective analysis of the clinical examination data of 87 patients with suspected ischemic stroke who were treated in Juye County People′s Hospital from June 2019 to June 2020 by transcranial Doppler ultrasound and carotid ultrasound.The differences in diagnostic results and diagnostic efficacy of single transcranial Doppler ultrasound and single carotid ultrasound and transcranial Doppler ultrasound combined with carotid ultrasound were compared and analyzed.Taking pathological results as the gold standard,the sensitivity of transcranial Doppler ultrasound combined with carotid ultrasound in the diagnosis of vessels with different degrees of occlusion was analyzed.Results Of the 87 patients with suspected ischemic stroke,73 were positive and 14 were negative by transcranial Doppler ultrasonography.Using carotid ultrasonography showed positive in 72 cases and negative in 15 cases.The combined ultrasonography showed that 75 cases were positive and 12 were negative.The accuracy of transcranial Doppler ultrasonography combined with carotid ultrasonography was 94.25%higher than that of transcranial Doppler ultrasonography(80.46%)and carotid ultrasonography(79.31%),and the difference was statistically significant(χ^(2)=7.493,8.467,P<0.05),the specificity was 81.82%higher than the specificity of transcranial Doppler ultrasound(36.36%)and the specificity of carotid ultrasound(36.36%),the difference was statistically significant(χ^(2)=4.701,4.701,P<0.05),The sensitivity of 96.05%was higher than that of transcranial Doppler ultrasound(86.84%)and the sensitivity of carotid ultrasound(85.53%),and the difference was statistically significant(χ^(2)=4.122,5.035,P<0.05).The overall sensitivity of transcranial Doppler combined with carotid ultrasonography in detecting vascular lesions was 92.98%.Conclusion Compared with the single applicat
