Preoperative tumor and edema volumes as predictors of ischemia and morbidity after intracranial meningioma surgery.

Key Points

• This study examines the predictive value of preoperative tumor volume and peritumoral brain edema volume for postoperative ischemia and morbidity.
• Evaluated preoperative tumor volume and peritumoral edema volume in patients undergoing meningioma surgery.
• Used volumetric analysis to assess the relationship between tumor and edema volumes and postoperative outcomes.
• Applied statistical significance threshold of p<0.05 for results.
• Identified preoperative tumor volume and edema volume as independent predictors of postoperative ischemia (p=0.017).
• Even small ischemic lesions (>2 cm³) linked to significant morbidity.
• Suggest volumetric biomarkers for improved surgical planning and outcomes.
