Research of correlation between MRI fluid-attenuated inversion recovery hyperintense vessel sign and prognosis in acute middle cerebral artery infarction / 重庆医学

ABSTRACT

Objective To investigate the significance of MRI T2 fluid-attenuated inversion recovery hyperintense vessel sign (FLAIR HVS)in clinical prognosis evaluation of the patients with acute middle cerebral artery irnfarction.Methods The data in 57 inpatients with acute middle cerebral artery infarction in our hospital from Aug.2013 to Aug.2015 were retrospectively analyzed.All cases were performed the intact MRI examination(ineluding FLAIR,DWI and MRA)and CTA.The infarct volume with DWI,national institute of health stroke scale(NIHSS)score and modified Rankin Scale(mRS)score on 30 d after discharge were performed the comparative analysis.Results Fifty-seven cases of middle cerebral artery occlusion were divided into the distal HVSgroup and non-distal HVS group(8 cases in proximal HVS group,21 cases in HVS negative group).The infarction volume of DWI sequence,NIHSS scores at admissiom and discharge and mRS score on 30 d after discharge in the distal HVS group were superior to those in the non-distal HVS group(P＜0.05).Conclusion MRI-T2 FLAIR sequence HVS has certain reference value in the prognosis evaluation in the patients with middle cerebral artery occlusion.
