Uterine fibroids are benign growths of the uterus that may cause pain, heavy bleeding or pressure symptoms in the pelvis. Fibroids are typically diagnosed by ultrasound or MRI. If symptoms are present, first line therapy is usually oral medication (birth control pills and anti-inflammatory medication). If the symptoms are not controlled, then consideration is given to fibroid embolization or surgery.
Using a fluoroscope, small particles are injected through a catheter to block the arteries that provide blood flow to uterine fibroids, causing them to shrink. This results in a significant decrease in menstrual bleeding and moderate reduction in size and pain associated with fibroids.
