Prediction for clinical outcome using prominent vessel sign in patients with subacute cerebral infarction

This study was to investigate the effect of prominent vessel sign (PVS) in patients with unilateral subacute infarction on hemorrhagic transformation (HT) and short-term prognosis by using susceptibility-weighted imaging (SWI). It was found that there were no significant differences in the incidence of prominent cortical veins (PCV), prominent medullary veins (PMV), PCV+PMV, SWI-ASPECT score and SWI-DWI mismatch score between two groups. Although higher than the HC group, there was no difference in venous MSV between HT and NHT groups. NIHSS score was negatively correlated with SWI-ASPECT score and DWI-ASPECT score and NIHSS score at discharge was negatively correlated with the proportion of PCV, PCV + PMV and MSV of CV. This study suggesting that PVS had little effect on HT in patients with unilateral subacute infarction, but related to worse short-term clinical status.
