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.

Abstract

Background: Ischemic complications remain a significant risk indicator of morbidity after meningioma surgery. While tumor size and extent of resection (EOR) are recognized risk factors, the prognostic impact of peritumoral brain edema volume (PTBEV) is not fully established. This study investigated whether preoperative tumor volume (TV) and PTBEV independently predict postoperative ischemia and neurological morbidity. Methods: value 2 cm³) can cause clinically relevant morbidity. Volumetric biomarkers should be integrated into surgical planning, with prospective multicenter validation warranted.
