经颅多普勒超声联合颈动脉超声在缺血性脑卒中患者中的应用研究

Transcranial Doppler Combined with Carotid Ultrasound in Patients with Cerebral Ischemic Stroke

目的探讨经颅多普勒超声(TCD)联合颈动脉超声(CU)在缺血性脑卒中(CIS)诊断中的应用价值。方法选取2018年8月至2019年8月本院收治的95例CIS患者为研究对象,所有患者行TCD检查、CU检查及头颅数字减影血管造影(DSA)检查并分析检查结果。结果TCD检查(灵敏度、漏诊率分别为71.7%、28.3%)与TCD联合CU检查(灵敏度、漏诊率分别为91.2%、8.8%)相比,差异有统计学意义(P<0.05);CU检查(灵敏度、漏诊率分别为64.0%、36.0%)与TCD联合CU检查相比,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在缺血性脑卒中诊断中具有高灵敏度、低漏诊率的优点,值得临床推广应用。

Objective To investigate the value of transcranial doppler(TCD)combined with carotid ultrasound(CU)in the diagnosis of cerebral ischemic stroke(CIS).Methods 95 CIS patients admitted to our hospital from August 2018 to August 2019 were selected as the study objects.All patients were examined by TCD,CU and digital subtraction angiography(DSA),and the results were analyzed.Results There were significant differences between TCD(sensitivity,missed diagnosis rate of 71.7%,28.3%)and TCD combined CU(sensitivity,missed diagnosis rate of 91.2%,8.8%,respectively)(P<0.05),Cu(sensitivity,missed diagnosis rate of 64.0%,36.0%,respectively)and TCD combined CU(P<0.05).Conclusion TCD combined with CU has the advantages of high sensitivity and low missed diagnosis rate in the diagnosis of ischemic stroke,which is worthy of clinical application.
