Cessation of blood flow forward to the fibroids, with reflux of contrast to arteries in posterior division of the left internal iliac artery following embolization.
Polyvinyl particlesPolyvinyl particles (PVA), used to embollize the arteries that supply the fibroids are tiny synthetic "plastic" particles that are the size of fine grains of sand ranging from 0.3 mm to 0.7 mm in diameter. PVA has been used for more than 20 years in embolization of other parts of the body with no known reports of any adverse side effects due to this embolization material.
