What happens to the small particles used during the UFE procedure?
The tiny particles used to block the blood supply in the uterine arteries are trapped within the small branches of the uterine arteries within the leftover fibroid tissue. They are too large to travel forward through the small capillary bed and they cannot move backwards in the uterine artery against the remaining incoming blood flow. These particles have not been shown to cause any long-term effects. The embosphere particles are currently the only embolization particles specially approved for uterine fibroid embolization by the Food and Drug Administration.
