No association of brain CT blend sign with functional outcomes in patients with spontaneous supratentorial intracerebral hemorrhage after craniotomy

Abstract

Objective: This study retrospectively analyzed the association of blend sign with long-term outcomes in patients who underwent craniotomy following spontaneous supratentorial intracerebral hemorrhage. Methods: A retrospective analysis was conducted on a cohort comprising 259 patients. Initially, patients were stratified into two groups: the blend sign group and the non-blend sign group. Subsequently, the neurological status of these patients was assessed using the NIHSS, GCS, and mRS following craniotomy. Furthermore, at six months post-craniotomy, patients were categorized into either the “good outcome group” or the “poor outcome group”. A multivariate regression analysis was applied to ascertain the independent correlation between the CT blend sign and prognosis. Results: No statistically significant disparities were observed in the proportion of patients experiencing favorable outcomes during the follow-up period between the two groups. Nevertheless, it is noteworthy that the incidence of the blend sign was higher among patients in the good outcome group compared to those in the poor outcome group. Multivariate regression analysis disclosed that poor outcomes following craniotomy was not associated with the blend sign. Conclusions: The presence of the blend sign may not serve as a reliable predictor of functional outcomes in patients undergoing craniotomy for spontaneous supratentorial ICH.
