摘　　要：目的:探讨磁共振仪液体衰减反转恢复序列(FLAIR)血管高信号征(HVS)预测急性脑梗死患者预后的应用价值。方法:选取2019年1月~2021年1月天津市武清区第二人民医院收治的急性脑梗死患者60例,根据患者T2 FLAIR图像上是否存在HVS,分为HVS组(n=22)和无HVS组(n=38)。比较两组血管狭窄程度、侧支循环分级、梗死体积及神经功能缺损(NIHSS)评分。结果:HVS组患者血管轻中度狭窄率为(9.09%)低于无HVS组(65.79%);重度狭窄、完全闭塞率分别为54.55%、36.36%,均高于无HVS组(26.32%、7.89%),P均<0.05。HVS组患者侧支循环分级为0级、1级比例分别为(9.09%、9.09%)均低于无HVS组(34.21%、31.58%);3级、4级比例分别为(31.82%、31.82%)均高于无HVS组(7.90%、5.26%),P均<0.05;两组2级侧支循环分级比例比较(P>0.05)。HVS组患者入院时脑梗死体积、NIHSS评分及出院时NIHSS评分均低于无HVS组(P均<0.05)。结论:FLAIR出现HVS是评估急性脑梗死患者血管狭窄程度及侧支循环分级的重要影像学征象,可指导临床进行早期干预,改善患者预后。Objective:To investigate the application value of fluid attenuated inversion recovery sequence(FLAIR)in predicting the prognosis of patients with acute cerebral infarction.Methods:A total of 60 patients with acute cerebral infarction admitted to the Second People's Hospital of Wuqing District of Tianjin from January 2019 to January 2021 were selected and divided into HVS group(n=22)and non-HVS group(n=38)according to the presence of HVS on T2 FLAIR images.The degree of vascular stenosis,collateral circulation grade,infarct volume and neurological impairment(NIHSS)score were compared between the two groups.Results:The rate of mild to moderate vascular stenosis in HVS group(9.09%)was lower than that in HVS group(65.79%).The rates of severe stenosis and complete occlusion were(54.55%,36.36%)higher than those of the group without HVS(26.32%,7.89%)(all P<0.05).The proportions of grade 0 and grade 1 collateral circulation in HVS group(9.09%,9.09%)were lower than those in HVS group(34.21%,31.58%).The proportion of grade 3 and grade 4(31.82%)was higher than that of HVS group(7.90%)and HVS group(5.26%)(all P<0.05).The proportion of grade 2 collateral circulation was compared between the two groups(P>0.05).The cerebral infarction volume at admission,NIHSS score and NIHSS score at discharge in HVS group were lower than those in HVS group(all P<0.05).Conclusion:FLAIR HVS is an important imaging sign to evaluate the degree of vascular stenosis and collateral circulation grading in patients with acute cerebral infarction,which can guide clinical early intervention and improve the prognosis of patients.
