Preoperative Embolization of Meningiomas with N-Butyl Cyanoacrylate

Meningiomas are often embolized before their surgical resection to reduce blood loss during surgery. Polyvinyl alcohol (PVA) particles have been the most frequently used material for embolization of meningiomas. We have used n-butyl cyanoacrylate (NBCA) as the first-choice material since 2001. Thirty-one meningiomas were embolized with NBCA. We report the result of embolization of meningiomas with NBCA in comparison with PVA particles.
