Intracranial hemangioblastomas (HBs) are hypervascular neoplasms mainly located in the posterior fossa of the central nervous system. Preoperative embolization of the feeding arteries is one proposal for reduction of intraoperative hemorrhage, although indications for the procedures should be evaluated carefully due to the potential complications. This retrospective study investigated clinical outcomes and complications of 15 patients with HBs in the posterior fossa to evaluate the safety and effectiveness of endovascular procedures as well as angiographical procedures. Surgical excision without presurgical embolization was performed in 8 cases, and excision with presurgical embolization was performed in 7 cases, using Guglielmi detachable coils with or without polyvinyl alcohol (GDC ± PVA) in 4 cases and only n-butyl 2-cyanoacrylate (NBCA) in 3 cases. The embolization was applied for selected cases in which feeding arteries were located in a deep site and hard to coagulate surgically. Partial embolization was achieved in 5 cases, and all feeders were successfully embolized in 2 cases. Total removal was achieved in 12 cases, and subtotal/partial removal was achieved in 3 cases. Subarachnoid hemorrhage with intratumoral hemorrhage occurred in 1 case during the angiographic procedure and in 1 case during the embolization procedures. The mean volume of intraoperative blood loss was clearly less in the NBCA group than in the GDC ± PVA group. HBs are mainly located in the posterior cranial fossa, so the risk of severe clinical complication may be high if vascular problems occur. In our series, presurgical embolization using NBCA made tumor removal safe and reduced bleeding volume in posterior fossa HBs.

“…Takeuchi (Montano et al, 2008) et al reported the treatment results from 27 cases of HB, of whom 8 underwent preoperative embolization, and found that preoperative embolization, especially partial occlusion, did not reduce the risk of surgical complications and mortality. The limitations of the study included not only small sample size and but also low level of embolization (5 patients with occlusion less than 70%).…”

“…[24][25][26] In addition, preoperative embolization is not generally used. 27 Therefore, better diagnostic accuracy with MR imaging is crucial. Our results suggest that the addition of ASL imaging could provide practical information to differentiate hemangioblastoma from metastasis in patients with only enhancing cerebellar masses.…”
