Uterine fibroid embolization
Uterine fibroid embolization involves withdrawing the blood supply to the fibroids. Using local anesthetic, the interventional radiologist slides a catheter across the femoral artery to the vessels supplying the fibroid. The radiologist then uses X-ray fluoroscopy to spray small, biologically-compatible tiny plastic particles into the artery which settle in the finest branches and block said branches. This causes the fibroids to shrink and the symptoms start to abate or disappear completely. The blood supply to the uterus is not at risk.
