What happens to the rest of the uterus after embolization?
We know from worldwide experience of more than 50,000 UFE cases that the uterus tolerates embolization very well. The PVA particles preferentially enter the fibroids, as their blood vessels are larger and have lower resistance to flow. While some normal uterine tissue is inevitable embolized, it is able to recruit collateral blood supply from the cervix, vagina, and ovaries. In less than 1% of cases this collateral circulation is inadequate, usually signified by continuing pain, and results in hysterectomy.
