Preoperative embolization of feeding arteries in glioblastoma: Technical strategies and clinical utility.

ABSTRACT:

Background

Maximal safe resection-balancing aggressive tumor removal with neurological preservation-is essential in glioblastoma surgery. Cerebral angiography enables identification of the dominant hemisphere, feeding arteries, and vessels crossing eloquent areas, thereby aiding intraoperative planning. Preoperative embolization of glioblastoma feeders may shorten operative time and reduce intraoperative bleeding, similar to its established role in extra-axial tumors. We hypothesized that embolization could serve not as a routine adjunct but as a targeted strategy for selected glioblastomas with deep-seated or hypervascular feeders that increase surgical complexity.

Methods

Between December 2023 and July 2025, 15 consecutive patients with glioblastoma underwent preoperative
