摘　　要：目的:探讨磁共振T2液体反转恢复序列高信号血管征(HVS)在评估急性脑梗死患者病情严重程度及预后的价值。方法:回顾性分析2021年5月~2023年5月收治的80例大脑中动脉急性脑梗死患者作为研究对象,根据有无T2FLAIR血管高信号征(HVS)分为观察组(HVS阳性40例)和对照组(HVS阴性40例),对患者的临床及影像学资料等进行收集汇总,比较两组患者血管狭窄程度、弥散加权成像上梗死灶体积,入院时与治疗半个月后的美国国立卫生研究院卒中量表(NIHSS)评分,综合分析HVS阳性与病情严重程度和预后的关系。结果:观察组大脑中动脉重度狭窄和闭塞占82.5%(33/40),对照组大脑中动脉重度狭窄和闭塞占37.5%(15/40),两组之间差异具有统计学意义(P<0.05)。观察组患者脑梗死的范围为(73.29±6.85)mm^(3),对照组患者脑梗死范围为(81.68±8.47)mm^(3),入院时观察组和对照组NIHSS评分分别为(8.83±1.21)分及(10.63±1.46)分,治疗半个月后两组NIHSS评分分别为(6.21±1.05)分及(9.98±1.32)分,两组对比差异均有统计学意义(P<0.05)。结论:急性脑梗死时,FLAIR序列出现血管高信号征提示神经功能障碍轻,梗死面积相对较小,临床预后较好。责任血管狭窄程度越严重,血管高信号征出现的概率越高,对评估病情严重程度及预后有非常重要的价值。Objective:To investigate the value of magnetic resonance T2 fluid inversion recovery sequence high signal vascular signs(HVS)in evaluating the severity and prognosis of acute cerebral infarction patients.Methods:80 patients with acute cerebral infarction of middle cerebral artery admitted from May 2021 to May 2023 were retrospectively analyzed.According to the presence or absence of T2 FLAIR hypersignal(HVS),they were divided into observation group(HVS positive 40 cases)and control group(HVS negative 40 cases).Clinical and imaging data of patients were collected and summarized,and the degree of vascular stenosis,infarct volume on DWI,NIHSS score at the time of admission and half a month after treatment were compared between the two groups.The relationship between positive HVS and the severity and prognosis of the disease was comprehensively analyzed.Results:Severe middle cerebral artery stenosis and occlusion accounted for 82.5%(33/40)of the observation group.In the control group,severe middle cerebral artery stenosis and occlusion accounted for 37.5%(15/40),and the difference between the two groups was statistically significant(P<0.05).The range of cerebral infarction in the observation group was(73.29±6.85)mm^(3),and that in the control group was(81.68±8.47)mm^(3).The NIHSS scores in the observation group and control group were(8.83±1.21)and(10.63±1.46),respectively.After half a month of treatment,NIHSS scores of the two groups were(6.21±1.05)points and(9.98±1.32)points,respectively,and the differences between the two groups were statistically significant(P<0.05).Conclusion:In acute cerebral infarction,the presence of vascular hypersignal on FLAIR sequence indicates mild neurological dysfunction,relatively small infarct area and good clinical prognosis.The more serious the degree of responsible vascular stenosis,the higher the probability of vascular hypersignal,which is very important for the evaluation of the severity and prognosis of the disease.
