What Is Pelvic Congestion Syndrome?

Pelvic congestion syndrome (PCS) is a chronic pain condition caused by the development of varicose veins within the pelvis and lower abdomen — most commonly affecting the ovarian and pelvic veins. Just as varicose veins in the legs develop when vein valves fail and blood pools in the vessel walls, pelvic varicose veins form when the valves in the ovarian or pelvic veins become incompetent, allowing blood to flow backward and accumulate. This pooling of blood causes the veins to dilate, engorge, and generate persistent pressure and pain in the pelvic region.

PCS is estimated to account for up to 30% of cases of chronic pelvic pain in women and is most commonly diagnosed in women of reproductive age — particularly those who have had multiple pregnancies. Despite its prevalence, pelvic congestion syndrome is frequently underdiagnosed because its symptoms overlap with many gynecological, gastrointestinal, and musculoskeletal conditions, and because the dilated pelvic veins that cause it are not visible on standard physical examination. If you have been experiencing chronic pelvic pain without a clear explanation, contact Minimally Invasive Specialists of Texas at (832) 583-2246 for a specialized evaluation in Pasadena, TX .

What Causes Pelvic Congestion Syndrome?

Pelvic congestion syndrome develops when the one-way valves in the ovarian or internal iliac veins fail to function properly, allowing blood to reflux (flow backward) and pool in the pelvic venous system. Several factors are known to contribute to this venous insufficiency:

  • Pregnancy: The most significant risk factor. During pregnancy, blood volume increases substantially and the growing uterus compresses pelvic veins, dramatically increasing venous pressure. Repeated pregnancies cause cumulative stretching of the vein walls and progressive valve damage. Women who have had two or more pregnancies are at significantly higher risk.
  • Hormonal influences: Estrogen is known to weaken vein walls and reduce their tone, making women more susceptible to venous dilation and reflux during reproductive years. PCS is rare after menopause, when estrogen levels decline.
  • Anatomical factors: In some women, the left ovarian vein drains at a sharp angle into the left renal vein, making it anatomically prone to reflux. Compression of the left renal vein between the aorta and superior mesenteric artery — a condition called nutcracker syndrome — can also contribute to pelvic venous hypertension.
  • Polycystic ovaries: Women with polycystic ovarian syndrome may have increased ovarian blood flow that contributes to ovarian vein dilation.

What Are the Symptoms of Pelvic Congestion Syndrome?

The hallmark of pelvic congestion syndrome is chronic pelvic pain — defined as pain below the navel lasting six months or longer — that is often poorly localized and may vary in character and intensity. Characteristic features of PCS-related pain include:

  • Dull, aching, or pressure-like pelvic pain: Most commonly felt deep in the lower abdomen or pelvis, often described as a dragging or heaviness.
  • Worsening with prolonged standing or sitting: Pain intensifies when upright and is partially relieved by lying down, as gravity worsens blood pooling in the pelvic veins.
  • Pain during or after intercourse (dyspareunia): Deep pelvic pain during or after sexual activity is one of the most characteristic symptoms of PCS.
  • Premenstrual flares: Many women experience a significant worsening of pelvic pain in the days before menstruation, when pelvic blood flow is increased.
  • Leg varicose veins: In some women, pelvic venous reflux extends into the thigh and leg veins, causing varicose veins in unusual locations such as the inner thigh, back of the calf, or perineum — a clue that pelvic venous insufficiency may be the underlying cause. This connects PCS closely to chronic venous disease of the legs.
  • Urinary urgency or frequency: Engorged pelvic veins can press on the bladder, causing irritative urinary symptoms.
  • Low back or buttock pain: Referred pain from pelvic venous congestion may radiate to the lower back, buttocks, or thighs.

Because these symptoms overlap significantly with conditions such as endometriosis, fibroids, irritable bowel syndrome, and interstitial cystitis, PCS is often not considered until other diagnoses have been excluded. If you have been through extensive workup without a satisfying explanation for your pelvic pain, call Minimally Invasive Specialists of Texas at (832) 583-2246 — PCS may be the missing diagnosis.

How Is Pelvic Congestion Syndrome Diagnosed?

Diagnosing PCS requires dedicated venous imaging to visualize the pelvic veins and demonstrate reflux — it cannot be diagnosed on clinical examination alone. At Minimally Invasive Specialists of Texas, our diagnostic evaluation may include:

  • Pelvic Ultrasound (Transvaginal or Transabdominal): Often the first imaging study performed. A Doppler ultrasound can identify dilated pelvic veins (greater than 4–5mm) and demonstrate retrograde venous flow, suggesting valvular incompetence. Our team also offers comprehensive vascular ultrasound evaluation.
  • CT or MR Venography: Cross-sectional imaging with venous phase contrast provides detailed anatomic mapping of the ovarian and pelvic veins, assessing the degree of dilation, reflux, and any contributing anatomical abnormalities such as nutcracker syndrome or May-Thurner syndrome.
  • Catheter Venography (Gold Standard): A minimally invasive diagnostic procedure performed by our interventional radiologists in which a catheter is guided into the ovarian and pelvic veins under fluoroscopic imaging and contrast is injected to directly visualize venous reflux. Catheter venography is both the most accurate diagnostic test and the procedure through which treatment is immediately delivered in the same session.

How Is Pelvic Congestion Syndrome Treated at Minimally Invasive Specialists of Texas?

At Minimally Invasive Specialists of Texas, we offer a full range of treatment options for pelvic congestion syndrome, from conservative management to definitive minimally invasive intervention:

  • Conservative Management: For mild symptoms, initial treatment may include hormonal therapies — such as medroxyprogesterone acetate or gonadotropin-releasing hormone (GnRH) agonists — that reduce pelvic blood flow by suppressing ovarian function. Pain management with NSAIDs may also provide symptomatic relief. However, conservative therapies do not eliminate the underlying venous reflux and symptoms typically recur when medications are stopped.
  • Ovarian Vein Embolization: The primary interventional treatment for PCS and the most effective long-term option. During this minimally invasive, catheter-based procedure, our interventional radiologists guide a thin catheter through a small puncture in the neck or groin vein into the dilated ovarian and pelvic veins. Embolic coils and/or sclerosant agents are then deployed to permanently seal off the incompetent veins, eliminating retrograde blood flow and relieving the venous congestion that causes pain. The procedure is performed under conscious sedation on an outpatient basis, with most patients returning home the same day and resuming normal activities within a few days. Clinical studies report significant or complete pain relief in 70–85% of women following ovarian vein embolization.
  • Concurrent Leg Vein Treatment: For women with associated varicose veins in the legs or inner thigh resulting from pelvic venous reflux, treatment of the pelvic source first — followed by vein ablation of the leg veins — provides the most comprehensive and durable result. Treating leg veins without addressing the pelvic reflux source is a common reason for varicose vein recurrence.

Frequently Asked Questions About Pelvic Congestion Syndrome

How is pelvic congestion syndrome different from endometriosis?

Pelvic congestion syndrome and endometriosis are both common causes of chronic pelvic pain in women and can produce overlapping symptoms, making accurate diagnosis essential. Endometriosis involves the growth of uterine lining tissue outside the uterus and is typically diagnosed via laparoscopy, while PCS is caused by varicose pelvic veins and is diagnosed through venous imaging. Some women may have both conditions simultaneously. At Minimally Invasive Specialists of Texas, our team uses advanced imaging including pelvic ultrasound and venography to identify the venous component of your pain and determine whether PCS is contributing to your symptoms. Call (832) 583-2246 for an evaluation in Pasadena, TX .

Can pelvic congestion syndrome occur in women who have never been pregnant?

Yes — while PCS is most common in women who have had multiple pregnancies, it can occur in nulliparous women as well. In these cases, anatomical factors such as nutcracker syndrome (compression of the left renal vein), congenital valve insufficiency in the ovarian veins, or hormonal influences may be responsible for the development of pelvic venous reflux. Our team at Minimally Invasive Specialists of Texas evaluates each patient individually to identify the underlying cause and recommend the most appropriate treatment approach regardless of obstetric history.

What is ovarian vein embolization and how long does the procedure take?

Ovarian vein embolization is a minimally invasive, catheter-based procedure performed by our interventional radiologists at Minimally Invasive Specialists of Texas under conscious sedation. A thin catheter is inserted through a small puncture — typically in the neck or groin — and guided under fluoroscopic imaging into the dilated ovarian and pelvic veins. Embolic coils and/or sclerosant agents are then deployed to permanently seal the incompetent veins. The entire procedure typically takes 45 to 90 minutes and is performed on an outpatient basis, with most patients going home the same day.

How effective is ovarian vein embolization for pelvic pain relief?

Ovarian vein embolization has a well-established track record for treating pelvic congestion syndrome. Published clinical studies consistently report significant or complete relief of chronic pelvic pain in approximately 70 to 85% of women following the procedure. Most patients begin to notice improvement within the weeks following treatment, with continued improvement over the following months as the treated veins are fully reabsorbed. Our team at Minimally Invasive Specialists of Texas will discuss realistic expectations and the likelihood of benefit during your pre-procedure consultation.

Will treating my pelvic veins also help my leg varicose veins?

For women whose leg or inner thigh varicose veins are being fed by pelvic venous reflux, treating the pelvic source with ovarian vein embolization is an essential first step. Without addressing the pelvic reflux, leg vein treatments such as ablation or sclerotherapy are significantly more likely to fail or recur over time. Once the pelvic veins have been treated at Minimally Invasive Specialists of Texas, any residual leg varicose veins can be addressed with our chronic venous disease treatments for comprehensive and durable results.

Is pelvic congestion syndrome covered by insurance?

Coverage for the diagnosis and treatment of pelvic congestion syndrome varies by insurance provider and plan. When PCS is documented as the cause of chronic pelvic pain and conservative treatments have been tried, ovarian vein embolization is generally considered medically necessary and may be covered by many major insurance plans. Our team at Minimally Invasive Specialists of Texas will assist you with coverage verification and prior authorization. Call (832) 583-2246 for help navigating your benefits in Pasadena, TX .

Can pelvic congestion syndrome affect fertility?

PCS itself does not directly cause infertility, though the chronic pelvic pain it produces can interfere with sexual intercourse and overall well-being. The dilated pelvic veins associated with PCS do not typically damage the ovaries or fallopian tubes. Ovarian vein embolization, when performed with appropriate technique that avoids the ovarian parenchyma, has not been shown to negatively impact ovarian function or fertility. However, if you are currently trying to conceive or planning a future pregnancy, we strongly recommend discussing this with both our team and your gynecologist before proceeding with treatment.
