Embolization of Meningiomas: Comparison of Safety between Calibrated Microspheres and Polyvinyl-Alcohol Particles as Embolic Agents

摘要

During embolization of meningiomas, intratumoral hemorrhagic complications may occur, especially with the use of small particle sizes. We compared the rate of hemorrhagic complications in 55 patients embolized with 400-μm calibrated microspheres (Embozene) with a historical cohort of 198 patients embolized with smaller PVA particles.
