AB BACKGROUND AND PURPOSE: Early neurologic deterioration (END) often occurs during hospitalization in single small subcortical infarction (SSSI). The objective was to identify imaging predictors of END.MATERIALS AND METHODS: SSSIs in the lenticulostriate artery within 72 hours of stroke onset from January 2015 to June 2021 were consecutively enrolled. The posteriority and laterality indexes were assessed on the second section from the top of the corona radiata section showing the lateral ventricle on DWI. A multivariate logistic analysis was used to explore the predictors of END.RESULTS: A total of 402 patients were included in this study, among whom 93 (23.1%) experienced END. The optimal cutoff points of the posteriority and laterality indexes for predicting END were given by a receiver operating characteristic curve. A multivariate logistic analysis showed that the posteriority index of ≥0.669 (OR: 2.53; 95% CI: 1.41–4.56; P = .002) and the laterality index of ≥0.950 (OR: 2.03; 95% CI: 1.03–4.00; P = .042) were independently associated with the risk of END. Accordingly, the SSSIs were further divided into 4 types: anterior lateral type (AL-type), anterior medial type (AM-type), posterior lateral type (PL-type), and posterior medial type (PM-type). After the multivariate analysis, in comparison with the AL-type, the AM-type (OR: 3.26; 95% CI: 1.10–9.65), PL-type (OR: 4.68; 95% CI: 1.41–15.56), and PM-type (OR: 6.77; 95% CI: 2.53–18.04) carried significantly elevated risks of END. The PM-type was associated with the highest risk of END.CONCLUSIONS: The PM-type was found to be associated with the highest risk of END.ALanterior lateralAManterior medialCRcorona radiataCSTcorticospinal tractENDearly neurologic deteriorationLSAlenticulostriate arterylSSSIlarge SSSILVlateral ventricleMADmaximum axial diameterPADparent artery diseasePLposterior lateralPMposteriormedial typepSSSIproximal SSSISSSIsingle small subcortical infarction
