Embolization is a nonsurgical procedure that deprives the fibroids of blood, causing them to shrink. To perform an embolization, a doctor will make a small incision into the groin area in order to place a thin tube (catheter) into a large blood vessel. The tube is flexible, allowing it to snake along inside the blood vessel until it arrives near the leiomyoma, at which time a solution of tiny plastic or gel particles is injected, which blocks the blood supply to the growth.
