[Abstract] Objective: To probe the relationship between fluid-attenuated inversion recovery vascular hyperintensities (FVH) and short-term cerebral infarction ocurrence in patients with transient ischemic attack (TIA) of the internal carotid artery.Materials and Methods: Retrospective analysis of MRI and clinical data in total 168 lesion-negative TIA patients with follow-up MRI examination during January 2010 to March 2019 in our hospital was executed, and then the multi-factor regression analysis was used to analyze whether FVH, internal carotid atherosclerosis (ICAS), etc. were the risk factors for the short-term cerebral infarction ocurrence in TIA patients.Results: Among eligible 168 TIA patients, 30 patients (17.86%) had unilateral FVH, 45 patients (26.79%) had DWI lesion on the follow-up MRI examination. According to the DWI lesion observed or not, these patients were thereby divided into two groups: R-DWI [+] group and R-DWI [-] group. In the multivariate analysis, both FVH (aOR=0.079, 95% CI=0.020-0.310, P<0.001) and ICAS (aOR=0.257, 95% CI=0.082-0.810, P<0.05) showed as an independent predictor of R-DWI [+]. Even though adjusted by FVH×ICAS (used to eliminate the interaction between FVH and ICAS), FVH was still associated with R-DWI [+].Conclusions: FVH is the risk factor for short-term cerebral infarction ocurrence in TIA patients.
