摘　　要：目的:探究磁共振(MR)高分辨血管壁成像对椎基底动脉迂曲延长症并发后循环多发脑梗死的诊断价值。方法:采用回归性分析法,选取2020年1月至2023年1月期间衡水市人民医院收治的138例椎基底动脉迂曲延长症患者,将其中54例并发后循环多发脑梗死患者纳入发生组,84例未并发后循环多发脑梗死患者纳入未发生组。所有患者均采用MR高分辨血管壁成像,比较两组患者基底动脉(BA),血流动力学指标收缩峰(Vs)、舒张峰流速(Vd)、平均峰(Vm)、脉动指数(PI)及血流阻力指数(RI),以及颅内责任斑块特征和椎BA分级。结果:未发生组患者BA的Vs、Vd、Vm、PI及RI指标均高于发生组,差异有统计学意义(t=11.742、4.323、7.367、4.824、2.351,P<0.05);未发生组颅内斑块狭窄程度(60.31±4.24)%。低于发生组的(73.67±5.96)%,差异有统计学意义(t=15.376,P<0.05)。两组斑块面积、斑块负荷、动脉重构指数以及偏心指数比较差异无统计学意义(P>0.05);未发生组患者椎BA分叉高度等级和椎BA偏移度等级均低于发生组,差异有统计学意义(χ^(2)=3.907、6.419,P<0.05)。结论:MR高分辨血管成像检查可清晰显示椎BA迂曲延长症患者血流速度、颅内斑块情况,并对椎BA进行分级,对预测椎BA迂曲延长症并发后循环多发脑梗死有显著应用价值。Objective:To explore the diagnostic value of magnetic resonance(MR)high-resolution imaging of vascular wall on vertebrobasilar artery tortuosity prolongation complicated by multiple cerebral infarction in posterior circulation.Methods:Regression analysis was used in this research.A total of 138 patients with vertebrobasilar artery tortuosity prolongation who admitted to Hengshui City People′s Hospital from January 2020 to January 2023 were selected.Among of them,54 patients who complicated with multiple cerebral infarction in posterior circulation were divided into the occurrence group,and 84 patients without multiple cerebral infarction in posterior circulation were divided into the non-occurrence group.All patients underwent high-resolution MR imaging of vascular wall,and the basilar artery(BA),hemodynamic indicators such as systolic peak(Vs),average peak(Vd),diastolic peak flow velocity(Vm),pulsatile index(PI),blood flow resistance index(RI),as well as intracranial responsibility plaque characteristics and vertebral basilar artery grading between two groups were compared.Results:The Vs,Vd,Vm,PI and RI indicators of patients in the non-occurrence group were significantly higher than those in the occurrence group,and the differences were statistically significant(t=11.742,4.323,7.367,4.824,2.351,P<0.05),respectively.The degree(60.31±4.24)%of intracranial plaque stenosis in the non-occurrence group was significantly lower than(73.67±5.96)%in the occurrence group,and the difference was statistically significant(t=15.376,P<0.05).There were no statistically significant differences in plaque area,plaque load,arterial remodeling index and eccentricity index between the two groups(P>0.05).The height level of vertebral basilar artery bifurcation and the degree of vertebral basilar artery deviation in the non-occurrence group were significantly lower than those in the occurrence group,with statistically significant differences(χ^(2)=3.907,6.419,P<0.05).Conclusion:MR high-resolution imaging of vascular wall can clear
