摘要
目的:分析超声大脑中动脉血流参数对脑小血管疾病(CSVD)患者脑白质病变(WLMs)程度的评估价值.方法:选取2021年1月至2024年1月期间延安大学附属医院收治的98例CSVD患者为研究组,另选取同期60例体检健康者为对照组,按照WLMs严重程度分为轻度组(n=42)、中度组(n=36)及重度组(n=20),通过超声检查收集受试者超声大脑中动脉收缩期峰值血流速度(Vs)、舒张期峰值血流速度(Vd)、平均血流速度(Vm)、搏动指数(PI)及屏气指数(BHI),对比研究组与对照组、不同WLMs严重程度的大脑中动脉血流参数.结果:研究组Vs、Vd、Vm及BHI均低于对照组,PI较对照组更高(P＜0.05).3组患者大脑中动脉血流参数对比存在显著差异(P＜0.05);与轻度组对比,中、重度组Vs、Vd、Vm及BHI均下降,PI升高(P＜0.05);重度组Vs、Vd、Vm及BHI均低于中度组,PI高于中度组(P＜0.05).结论:超声大脑中动脉血流参数与CSVD患者WLMs严重程度呈显著相关,可作为早期评估WLMs严重程度的无创指标.
Abstract
Objective:To analyze the value of ultrasound blood flow parameters of middle cerebral artery in evaluating the degree of white matter lesions(WMLs)in patients with cerebral small vessel disease(CSVD).Methods:A total of 98 patients with CSVD who were admitted to Yan'an University Affiliated Hospital between January 2021 and January 2024 were selected as the study group.Mean-while,60 healthy individuals were selected as the control group.The patients were divided into mild group(n=42),moderate group(n=36)and severe group(n=20)according to the severity of WMLs.Ultrasound examination was conducted to collect peak systolic blood flow velocity(Vs),peak diastolic blood flow velocity(Vd),mean blood flow velocity(Vm),pulsatility index(PI)and breath holding in-dex(BHI)of middle cerebral artery.The blood flow parameters of middle cerebral artery were compared between the study group and the control group as well as among patients with different severity of WMLs.Results:Vs,Vd,Vm and BHI of the study group were lower than those of the control group,and PI was higher than that of the control group(P＜0.05).There were significant differences in blood flow parameters of middle cerebral artery among patients with different severity of WMLs(P＜0.05).Compared with mild group,there were decreases in Vs,Vd,Vm and BHI,and increases in PI in moderate group and severe group(P＜0.05).Compared with moderate group,there were decreases in Vs,Vd,Vm and BHI,and increase in PI in severe group(P＜0.05).Conclusion:Ultrasound blood flow pa-rameters of middle cerebral artery are significantly correlated with the severity of WMLs in patients with CSVD,and can serve as non-in-vasive indicators for early evaluation of the severity of WMLs.
