Group 1: 26 patient will be treated with Bead-block microspheres - 700-900 µm microspheres or combinations of one vial 2 ml of 500-700 µm microspheres, follow by 700-900 µm microspheres until blood flow stop ( " cut the tree" appearance).
Group 2: 26 patient will be treated with Embosphere; 500-900 µm until "near-stasis" flow stop in the uterine artery.
Clinical and Technical success will be examined, and radiological follow-up 3 and 12 months after embolization using MR contrast-enhanced examination in a Bead Block group and only 3 months control in Embosphere group to assess total fibroid burden infraction degree and eventually residual contracts fibroid enhancement.
Quantitative MRI dominant fibroid characteristic for and 3 months after an intervention to examine eventually potential of as a possible predictor of the volumetric response of the uterine fibroid.
Retrospective study compromised all patient treated between January 2001 until January 2011 with follow up to January 2014, and re-intervention as well as complications rate analysis.
