摘　　要：目的:观察彩超声造影技术(CEUS)检查缺血性脑卒中患者的颈动脉、椎动脉以及脑血流灌注指标的作用。方法:选取2018年9月至2019年3月的缺血性脑卒中患者50例为研究组,进行超声造影技术检查指标,包括右侧颈动脉(rICA)、左侧颈动脉(lICA)、右侧椎动脉(rVA)、左侧椎动脉(lVA)血流量以及前循环脑血流灌注量(aCBFV)、后循环脑血流灌注量(pCBFV)、全脑血流灌注量(tCBFV)。结果:前循环脑梗死患者的aCBFV明显低于后循环脑梗死(P<0.05)、pCBFV明显高于后循环脑梗死(P<0.05)。不同分型前循环以及后循环脑梗死患者的tCBFV、aCBFV、pCBFV均无显著性差异(P>0.05)。结论:超声造影技术能够有效检查缺血性脑卒中患者的动脉血流情况,能够较为准确评估脑灌注血流,对于疾病诊断有良好的作用。Objective:To observe the effect of contrast-enhanced color ultrasound(CEUS)on carotid artery,vertebral artery and cerebral blood flow perfusion in patients with ischemic stroke.Methods:50 patients with ischemic stroke from September 2018 to March 2019 were selected as the study group.Contrast-enhanced ultrasonography(CEUS)was used to measure the blood flow of right carotid artery(rICA),left carotid artery(LCA),right vertebral artery(rVA),left vertebral artery(lVA),anterior cerebral blood flow perfusion(aCBFV),posterior cerebral blood flow perfusion(pCBFV),and whole cerebral blood flow perfusion.(tCBFV).Results:The aCBFV of patients with anterior circulation cerebral infarction was significantly lower than that of patients with posterior circulation cerebral infarction(P<0.05),and pCBFV was significantly higher than that of patients with posterior circulation cerebral infarction(P<0.05).There were no significant differences in tCBFV,aCBFV and pCBFV among different types of cerebral infarction patients with anterior and posterior circulation(P>0.05).Conclusion:Contrast-enhanced ultrasound can effectively check the arterial blood flow in patients with ischemic stroke,and can accurately evaluate cerebral perfusion blood flow,which has a good role in the diagnosis of disease.
