Polyvinyl Alcohol Particle Size for Uterine Artery Embolization: A Prospective Randomized Study of Initial Use of 350-500μm Particles versus Initial Use of 500-700μm Particles

The initial use of PVA particle sizes 350-500 μm was associated with a higher mean pain score during and after UAE, although the outcome at 6 months was similar compared with the initial use of particle sizes 500-700 μm.
