Acrylamido Polyvinyl Alcohol Microspheres for Uterine Artery Embolization: 12-month Clinical and MR Imaging Results

Acrylamido PVA microspheres are a clinically effective and safe embolic agent for UAE. The use of 500-700-μm spheres and a limited embolization results in an unacceptably high rate of failed tumor infarction. Superior imaging results and fewer repeat interventions can be achieved with use of 700-900-μm spheres and stasis as the angiographic endpoint.
