Pelvic congestion syndrome (PCS) is estimated to cause as many as 30% of cases of chronic pelvic pain in women.[2] It occurs when varicose veins (like those often seen on the legs) develop in the pelvic region, often following pregnancy. Because of the changes that happen within a woman’s body during gestation, multiple pregnancies increase a woman’s risk of developing PCS.
Varicosities develop as a result of weakened veins. The valves within these veins are no longer able to close properly, allowing blood to pool. This can result in persistent pain, which is often worse after long periods of standing, in the evenings, and during and after intercourse. It’s often improved by lying down. Additional symptoms that may appear include
Particularly if you experience persistent pelvic pain that lasts more than six months, your doctor may recommend tests to determine whether PCS is an underlying cause. A number of tests can be used to identify PCS. Often, ultrasound is the first choice because it’s a non-invasive way to detect varicosities and evaluate blood flow in the veins.[4] CT, MRI, laparoscopy, and venography are other tests that may be used for this purpose.[5]
Some PCS patients experienced improvement in their symptoms with hormonal medications. For those who do not, vein embolization and surgery to remove damaged veins are possible treatments.[6] Vein embolization is often preferred because it’s minimally invasive and involves less risk and less recovery time than open surgery. Additionally, the success rate of this procedure is reported to be as high as 85%.[7]
During a vein embolization procedure, an interventional radiologist uses X-ray imaging to insert a thin catheter into a vein in the groin and guide it into the varicose veins. The radiologist uses the catheter to insert tiny coils and sclerosing agents that cause the blood to clot and the vein to close. The procedure is performed in a hospital, typically using IV sedation.
Vein embolization uses IV contrast dye, which can cause allergic reaction in some patients. Be sure to tell your doctor if you’ve experienced an allergic reaction to contrast material in the past. Like any invasive procedure, embolization carries a risk of infection. Other risks include damage to blood vessels and improper placement of the embolic agent, which can deprive healthy tissue of oxygen. Talk to your doctor to learn more about risks of the procedure and how those risks will be mitigated.[8]
Interventional radiologists at Iowa Radiology perform vein embolization as a treatment for PCS at UnityPoint Iowa Methodist Medical Center in Des Moines.
