摘　　要：目的探讨经颅多普勒超声(TCD)在监测脑血管狭窄后血流变化中的应用效果,评估其对临床治疗决策的影响。方法本研究纳入2023年5月至2024年3月期间江苏大学附属医院确诊的60例脑血管狭窄患者。所有患者在入组前均接受连续的TCD监测,包括血流速度、血流方向和频谱形态等,并记录参数,评估脑血管狭窄后血流动力学的变化情况,采用描述性统计和推断性统计方法对收集的数据进行分析,包括t检验、方差分析(ANOVA)和相关性分析。结果TCD监测结果显示,重度狭窄后患者脑血管的血流速度显著增快(P<0.01),频谱形态出现显著变化,包括湍流和舒张期血流反向。统计分析表明,脑血管狭窄后血流速度与血管狭窄程度呈正相关。结论TCD监测为脑血管狭窄后血流变化提供了重要信息,对指导临床治疗和评估预后具有重要价值。Objective:To explore the application effect of transcranial Doppler(TCD)in monitoring blood flow changes after cerebral vascular stenosis,and to evaluate its influence on clinical treatment decision.Methods:This study included 60 patients with cerebrovascular stenosis diagnosed in the Affiliated Hospital of Jiangsu University from May 2023 to March 2024.All patients received continuous TCD monitoring before entering the group,including blood flow velocity、blood flow direction and spectral morphology,and recorded parameters to evaluate the hemodynamic changes after cerebrovascular stenosis.Descriptive statistics and inferential statistics were used to analyze the collected data,including T-test、analysis of variance(ANOVA)and correlation analysis.Results:TCD monitoring results showed that the blood flow velocity of cerebral vessels in patients with severe stenosis increased significantly(P<0.01),and the spectral morphology changed significantly,including turbulence and diastolic blood flow reversal.Statistical analysis shows that the blood flow velocity after cerebrovascular stenosis is positively correlated with the degree of vascular stenosis.Conclusion:TCD monitoring provides important information for blood flow changes after cerebrovascular stenosis,and is of great value in guiding clinical treatment and evaluating prognosis.
