Abstract:
Objective:To investigate the correlation between fluid-attenuated inversion recovery vascular hyperintensities(FVH) and prognosis and cognitive dysfunction in patients with internal watershed cerebral infarction(IWI).Methods:Totally106 patients with IWI were selected.According to FVH diagnostic criteria, there were 59 cases in FVH (+ ) group and 47 cases in FVH (-) group.Demographic data and risk factors of cerebrovascular disease were collected to assess the clinical neurological function of the patients at admission and discharge, and the short-term outcome was assessed by modified RANKIN scale (mRS) score at 90 days after discharge.The cognitive function of patients was assessed by MMSE scale.Results:There was no significant difference in NIHSS score between the two groups on admission ( P>0.05). The NIHSS score of FVH (+ ) group((3.37±2.33))at discharge was significantly lower than that of the FVH (-) group ((4.43±2.72))( P<0.05). The rate of neural function improvement and mRS score after discharge 90 days in FVH (+ ) group((42.16±12.20)%, (1.75±1.12)) was significantly higher than that in FVH (-) group((37.58±13.64)%, (2.19±1.38))(both P<0.05). The scores of orientation, recall and language ability of MMSE in FVH (+ ) group ((9.26±0.21), (1.66±0.27), (7.69±0.44) respectively)were significantly lower than those of FVH (-) group((9.43±0.36), (1.83±0.34), (7.85±0.28) respectively)(all P<0.05). There was no significant difference in memory, attention and calculation between the two groups ( P>0.05). Conclusion:FVH has no correlation with the severity of IWI patients when they are admitted to hospital.FVH may be used as an imaging sign for prognosis evaluation of patients with IWI .However, IWI patients with FVH may have more severe cognitive impairment.
