Knowledge of the location tumor-feeding arteries is necessary for safe surgery intracranial meningiomas. Hence, this retrospective study aimed to comprehensively analyze distribution arteries. Patients who underwent meningioma at our institution between 2015 and 2023 were included in study. The tumor attachment sites evaluated based on results preoperative examinations. classified as non-skull bases (convexity, parasagittal, falx) or skull (anterior base, sphenoid ridge, sphenopetroclival, petrous, tentorial, cerebellar convexity, foramen magnum). These tumors further subdivided according their areas. Among 180 patients included, identified 177 (98.3%). In 67 with base meningiomas, middle meningeal artery primarily functioned a anterior regions (78 108 feeding arteries, 72.2%), while extracranial served posterior region (20 37 54.1%). Conversely, meningiomas exhibited higher frequency having derived from internal carotid (132 278 arteries; 47.5%); these are often found deepest part surgical field during resection require careful intraoperative handling. Tumor-feeding originate different dural depending site. findings could help enhance safety, especially have not undergone angiography.
