A new, minimally invasive technique to help alleviate pain and bleeding associated with uterine fibroids. Under x-ray guidance, using sedation and a local anesthetic, a small catheter is advanced into the arteries that supply the fibroid tumors. Once in the position, small particles are injected into the blood vessel to block blood flow. This is referred to as embolization. Without blood flow, the fibroids infarct or die. The tumors then shrink over time and become scar tissue. Most women experience significant pain relief and reduction in bleeding within one month after the outpatient procedure.
