Randomized Controlled Trial Comparative StudyPreoperative embolization of meningiomas with polyvinyl alcohol particles: The benefits are not outweighed by risks.
The purpose of this study was to define the feasibility, the efficacy and the safety of preoperative embolization (POE) of meningiomas using polyvinyl alcohol (PVA) particles. ⋯ POE of meningiomas using PVA particles is effective in reducing surgical time, when extensive tumor devascularization is achieved. However, radiation exposure, the duration of procedures and complications related to POE with PVA particles do not justify this technique in most patients.
