Pelvic embolization is a treatment to destroy varicose veins of the ovaries and pelvis, which may be causing pelvic congestion syndrome (PCS). This method also can be used to treat tumors and vascular malformations that either cannot be removed surgically or would involve great risk if surgery were attempted. The procedure is carried out under local anesthesia with intravenous sedation.
Using a catheter, a needle is placed directly into the abnormal ovarian vein. Sclerosing agents (chemicals that provide irritation or inflammation) are injected into the varicose veins, and small metal coils or plugs are placed to clot the blood and block its flow.
What to Expect
This procedure is typically performed on an outpatient basis. Patients can return to normal activity in about a week. After ovarian vein embolization, approximately 75 percent of patients will report improvement in their symptoms. Multiple sessions may be required because multiple veins may need to be embolized.
