Abstract |
Background and purpose |
Pre-surgical embolization of large intracranial meningioma has been demonstrated to decrease blood loss and to improve the resectability of the tumor. Few reports have evaluated the risk and benefits of using Onyx in this indication. The objective of our study was to assess the efficiency and safety of pre-surgical embolization in a consecutive series of intracranial meningioma using Onyx.
Materials and methods |
We conducted a retrospective study of consecutive patients treated from 2010 to 2018 with pre-surgical embolization with Onyx for intracranial histologically-proven meningioma. Safety was evaluated by a report of the complications related to the procedure while efficacy was assessed on angiographic and histopathologic criteria.
Results |
Forty-four meningioma in 44 patients treated with pre-surgical embolization were included in this study. Proximal artery occlusion was obtained in 97.6% (41/42) of the cases and good intra-tumoral penetration was achieved in 75.6% (31/41). Embolic agent inside blood vessels was identified in 63.5% (28/44) of cases. Embolization-induced necrosis was present in 79.6% (35/44) of cases. Six complications have been encountered (13.6%); 3 were stated as minor complications (6.8%) and 3 as major occurring in case of trans-ophthalmic route (6.8%).
Conclusions |
The present work is to date the largest study to evaluate intracranial meningioma embolization using Onyx. Onyx's allowed good intra-tumoral penetration and proximal artery occlusion in most cases but carries a higher risk of complication in case of ophthalmic supply.
