Results: The embolized feeders consisted of the posterior inferior cerebellar artery in five patients, superior cerebellar artery (SCA) in one patient, and occipital artery (OA) in one patient. The embolic materials consisted of polyvinyl alcohol (PVA) in two patients, n-butyl-2-cyanoacrylate (NBCA) in four patients, and the combination of PVA and NBCA in one patient. Surgery was performed 1–4 days after embolization. The mean volume of intraoperative blood loss was 593 mL. In all patients, total surgical removal of the tumor was possible in the absence of non-autologous blood transfusion. Furthermore, embolic blood vessels could be identified during surgery in all patients, contributing to intraoperative orientation. Periprocedural complication related to TAE, cerebellar infarction related to embolic-material migration into a normal blood vessel occurred in one patient (13%).
