摘要: 本文探讨急性大脑中动脉供血区脑梗死磁共振成像T2液体衰减反转恢复序列(MRI T2-FLAIR)上高信号血管征(HVS)出现情况及与大脑中动脉狭窄情况、脑梗死面积的关系。选取125例急性大脑中动脉供血区脑梗死患者,均给予MRI T2-FLAIR序列扫描,分析HVS阳性和阴性患者临床资料、大脑中动脉狭窄程度、脑梗死面积及侧支循环等差异。HVS阳性患者美国国立卫生研究院卒中量表(NIHSS)评分明显高于HVS阴性患者(P<0.05)。HVS阳性患者大脑中动脉狭窄程度、脑梗死面积、有侧支循环比例明显高于HVS阴性患者(P<0.05)。HVS与NIHSS评分、大脑中动脉狭窄、脑梗死面积及侧支循环呈正相关(P<0.05)。远端HVS阳性患者NIHSS评分、大脑中动脉狭窄程度明显低于近端HVS阳性患者(P<0.05)。急性大脑中动脉供血区脑梗死患者MRI T2-FLAIR上存在HVS,其大脑中动脉狭窄程度较重,脑梗死面积较大。

Abstract: This paper discussed the occurrence of hyperintense vessel sign (HVS) on T2 fluid attenuation inversion recovery sequence (MRI T2-FLAIR) of acute middle cerebral artery donor cerebral infarction and its relationship with middle cerebral artery stenosis and cerebral infarction area. 125 patients with acute cerebral infarction in the blood supply area of middle cerebral artery were given MRI T2-FLAIR sequence scanning, the clinical data, stenosis degree of middle cerebral artery, cerebral infarct area and collateral circulation and so on of HVS positive and negative patients were analyzed. The National Institutes of Health stroke scale (NIHSS) score of HVS positive patients was significantly higher than that of HVS negative patients (P<0.05). The degree of middle cerebral artery stenosis, cerebral infarction area and the proportion of collateral circulation in HVS positive patients were significantly higher than those in HVS negative patients (P<0.05). HVS was positively correlated with NIHSS score, middle cerebral artery stenosis, cerebral infarction area and collateral circulation (P<0.05). The NIHSS score and the degree of middle cerebral artery stenosis in distal HVS positive patients were significantly lower than those in proximal HVS positive patients (P<0.05). HVS is found on T2-FLAIR of MRI in patients with acute cerebral infarction in the blood supply area of middle cerebral artery, has severe stenosis of middle cerebral artery and large cerebral infarction area.

Key words: MRI T2 liquid attenuation inversion recovery sequence, acute middle cerebral artery infarction, degree of stenosis, cerebral infarction area, hyperintense vessel sign
