Preoperative embolization of glioblastoma-feeding arteries may provide a clear and bloodless surgical field, enhances spatial orientation through radiopaque contrast marking, and facilitates precise intraoperative localization. By reducing intraoperative bleeding, surgical complexity, and anesthesia time, this selective technique may decrease the overall invasiveness of glioblastoma surgery. When performed via a minimally invasive distal radial approach, preoperative embolization is a safe, feasible, and practical adjunct that enhances the precision and efficiency of glioblastoma resection.
Uchida et al. (2026) studied this question.
