Pelvic Venous Disease Embolization

Pelvic venous disease, often referred to as pelvic congestion syndrome (PCS), occurs when the valves within the ovarian and/or internal iliac veins fail, allowing blood to flow backward (reflux) and pool in the pelvis instead of returning efficiently to the heart. This venous pooling causes the affected veins to become chronically dilated and engorged — similar to varicose veins in the legs, but located deep within the pelvis where they are invisible from the outside. The condition predominantly affects women of reproductive age, especially those who have had multiple pregnancies, as pregnancy dramatically increases pelvic venous pressure and volume. It is estimated that pelvic venous disease accounts for up to 30% of chronic pelvic pain cases in women — yet remains one of the most underdiagnosed conditions in gynecology because standard pelvic ultrasound and exams often miss it.

Classic symptoms include chronic dull, aching pelvic pain that worsens with prolonged standing, at the end of the day, during or after intercourse (dyspareunia), and around menstruation. Many women also notice visible varicose veins around the vulva, buttocks, or inner thigh — a key clue that’s often overlooked. Because routine pelvic ultrasound is typically performed with the patient lying down (which can decompress engorged veins) and standard gynecologic workups focus on the uterus and ovaries rather than venous anatomy, pelvic congestion syndrome is missed in the majority of affected women for years. Many patients have been told their pain is “normal,” psychological, or due to endometriosis before ultimately receiving the correct diagnosis. Diagnosis is best confirmed with pelvic venography, transvaginal ultrasound with Doppler performed in a standing or Valsalva position, or contrast-enhanced MR/CT venography.

The underlying physiology is similar — incompetent vein valves causing reflux and pooling — but the anatomic target and approach differ. Leg varicose vein treatment (sclerotherapy, ablation) targets superficial veins accessible from the skin surface. Pelvic vein embolization requires catheter-based access into deep pelvic veins (the ovarian veins and internal iliac vein tributaries) that are not accessible externally. An interventional radiologist navigates a catheter from a vein in the neck or groin down into the pelvis under fluoroscopic guidance, then closes the refluxing veins from within using coils, vascular plugs, and/or a sclerosing agent. This endovascular approach avoids any abdominal or pelvic surgery.

Good candidates are women with chronic pelvic pain (typically lasting more than 6 months) that worsens with standing and improves with lying down, especially when accompanied by visible vulvar, perineal, or thigh varicosities, and confirmed venous reflux/dilation on imaging. Candidates should have had other common causes of pelvic pain (endometriosis, fibroids, ovarian cysts, pelvic inflammatory disease) appropriately evaluated and ruled out or addressed. Pelvic vein embolization is not a treatment for pain caused primarily by these other gynecologic conditions, although pelvic venous disease can coexist with them. A multidisciplinary evaluation with your gynecologist and Dr. Chahal helps clarify whether venous disease is a primary or contributing driver of your symptoms.

The procedure is performed under conscious sedation and local anesthesia. Venous access is typically obtained through the right internal jugular vein (neck) or femoral vein (groin) with a tiny needle puncture. A catheter is advanced under fluoroscopic guidance into the gonadal (ovarian) veins and internal iliac vein branches. Venography — injecting contrast dye — confirms the diagnosis by demonstrating reflux and dilated, tortuous pelvic varices. Once confirmed, Dr. Chahal deploys embolic coils and/or vascular plugs to permanently close the incompetent veins, sometimes combined with a sclerosing foam to treat smaller collateral varices. The procedure takes 60–90 minutes, and most patients go home the same day with a small bandage at the access site.

Multiple published series report that 75–85% of women experience significant or complete relief of pelvic pain following embolization, with average pain score improvements of around 70% at 6–12 months. Improvement in visible vulvar and leg varicosities is also common, as the abnormal venous pressure driving them is relieved. Most women notice improvement within the first 4–6 weeks, with continued gains over 3–6 months as the treated veins fully close and collateral congestion resolves.

Recovery is typically quick: most patients experience mild pelvic or back discomfort for a few days, managed with over-the-counter pain medication, and resume normal activities within 1–2 days. Strenuous exercise and heavy lifting are restricted for about 1 week. Complication rates are low (under 3%) and may include access-site bruising, transient discomfort from coil placement, or — rarely — coil migration, which is minimized through careful technique and appropriately sized devices. There is no impact on fertility or future pregnancy, and the procedure does not affect ovarian hormone production, since only the draining vein (not the ovarian artery) is treated.

Recurrence is uncommon when all refluxing veins are adequately treated in the initial procedure, but pelvic venous disease can occasionally involve additional collateral pathways that become apparent only after the primary veins are closed. If symptoms persist or recur, follow-up venography can identify and treat any residual or newly apparent incompetent veins. Long-term outcome studies show durable symptom relief in the large majority of treated patients at 2–5 year follow-up.

Pelvic vein embolization for symptomatic pelvic congestion syndrome is increasingly recognized and covered by Medicare and commercial insurers when supported by appropriate imaging documentation of venous reflux and a clinical history consistent with the diagnosis.
