Pelvic Congestive Syndrome

Pelvic Congestive Syndrome (PCS), also known as Pelvic Venous Insufficiency, develops due to improper functioning of the veins in the pelvic region. This condition arises when the valves within the pelvic veins become weakened or damaged, causing blood to pool and accumulate. The increased pressure in the veins can lead to venous congestion, resulting in various symptoms.

What is Pelvic Congestive Syndrome?

Pelvic Congestion Syndrome (PCS) or pelvic venous insufficiency, is a vascular condition that primarily affects women, causing chronic pain and discomfort in the pelvic region. It occurs when veins in the pelvis become enlarged and engorged, allowing blood to pool in the pelvis rather than returning to the heart. This chronic venous insufficiency results in pelvic heaviness, pressure, and pain.

While the exact prevalence is unknown, PCS is estimated to affect up to 30% of women. Pelvic varicose veins often develop during pregnancy.

Causes & Symptoms of Pelvic Congestive Syndrome

The hallmark symptom of Pelvic Congestion Syndrome (PCS) is chronic pelvic pain that is often described as a dull ache or heaviness. This pain may worsen after prolonged periods of sitting or standing and may be alleviated when lying down.

Symptoms of PCS can be similar to other conditions, such as endometriosis, ovarian cysts, and pelvic inflammatory disease. It is often diagnosed after other conditions have been ruled out. While the exact cause of PCS is not fully understood, it is thought to be due to a combination of factors.

Causes of Pelvic Congestive Syndrome

  • Weakened valves in the pelvic veins
    The veins in the pelvis carry blood back to the heart. If the valves in these veins are weakened, blood can flow backwards, causing the veins to swell.
  • Increased pressure in the pelvic veins
    The pressure in the pelvic veins can increase during pregnancy, childbirth, and menopause. This can also lead to the development of PCS.
  • Hormonal changes
    Estrogen and progesterone can relax the walls of the veins, making them more likely to swell. This may be a factor in the development of PCS in women.
  • Genetics
    Some people may be more likely to develop PCS due to their genes.

Symptoms of Pelvic Congestive Syndrome

  • Pelvic pain
    The pain is often described as a dull ache or a feeling of fullness in the pelvis. It can be worse during or after standing, walking, or sexual activity.
  • Pressure or heaviness in the pelvis
    Some people with PCS may feel pressure or heaviness in the pelvis.
  • Varicose veins in the pelvis or legs
    Varicose veins are enlarged, twisted veins that can be seen on the surface of the skin. They are most common in the legs, but they can also occur in the pelvis.
  • Other symptoms
    Other symptoms of PCS can include urinary frequency or urgency, painful intercourse, irregular menstrual periods, fatigue, and mood swings.

Testing & Diagnosis for Pelvic Congestive Syndrome

The first step in diagnosing pelvic congestive syndrome (PCS) is a thorough medical history and physical exam. Your doctor will ask about your symptoms, medical history, and family history. They will also perform a pelvic exam to look for any abnormalities. Information about menstrual cycles, exacerbating factors, and any history of vein-related issues will also be considered. A physical examination may involve palpation of the pelvic region to identify areas of tenderness or swelling. 

If PCS is suspected, the following tests might be conducted to ascertain the condition:

  • Pelvic ultrasound
    This test uses sound waves to create images of the pelvic organs and veins. It is a non-invasive test that can be used to look for dilated veins and backflow of blood. However, it is not as sensitive as other imaging tests for PCS.
  • Pelvic venography
    This test involves injecting a dye into the veins of the pelvis and then taking X-rays. The dye makes the veins visible on the X-rays, which can help to identify any abnormalities. This is the most sensitive imaging test for PCS, but it is also the most invasive.
  • MRI
    This test uses a magnetic field and radio waves to create detailed images of the body. It can be used to look for dilated veins and backflow of blood in the pelvis. MRI is a more expensive test than pelvic ultrasound, but it is less invasive than pelvic venography.
  • Blood tests
    Blood tests can be used to rule out other conditions that can cause pelvic pain, such as an infection or an autoimmune disorder.
  • Urine tests
    Urine tests can be used to check for infections or other problems with the urinary tract.
  • Laproscopy
    This is a minimally invasive surgery that allows your doctor to look inside the pelvis. It can be used to rule out other causes of pelvic pain and to confirm the diagnosis of PCS.

PCS Treatments

There is no cure for PCS, but the symptoms can be managed with treatment. An individualized, multidisciplinary approach combining several techniques often provides the greatest benefit. Pelvic vein embolization offers the most direct treatment of the underlying cause. The following treatments can effectively manage symptoms and improve comfort:

  • Pelvic vein embolization
    This minimally invasive procedure blocks abnormal pelvic veins using coils or plugs to prevent blood pooling. It is considered the first-line treatment for PCS.
  • Pain medications
    Over-the-counter nonsteroidal anti-inflammatory drugs (NSAIDs) or other analgesics may temporarily alleviate PCS pain. Prescription pain medications may also be necessary for more severe pain.
  • Hormonal therapy
    Low-dose estrogen-progesterone combinations may help some women by stabilizing veins. This is especially effective for women who experience PCS during menopause.
  • Anticoagulants
    Drugs like low molecular weight heparin can address any clotting issues that may be contributing to PCS pain.
  • Pelvic physical therapy
    Stretches and exercises to ease muscle tension contributing to pain can be helpful for PCS. A physical therapist can teach you specific exercises that are right for you.
  • Diet and lifestyle changes
    Losing weight, regular exercise, and limiting prolonged standing can provide some relief for PCS symptoms. Eating a healthy diet and avoiding alcohol and caffeine may also be helpful.
  • Compression underwear
    Snug elastic shorts or underwear may help control symptoms of PCS. This can help to reduce the pressure on the pelvic veins.
  • Mental health counseling
    Cognitive behavioral therapy and support for coping with chronic pain can be helpful for people with PCS. A therapist can teach you skills to manage your pain and improve your quality of life.
  • Trigger point injections
    Steroid injections into painful pelvic trigger points may provide temporary relief for PCS pain.
  • Surgery
    Hysterectomy or vein ligation may be other options if minimally invasive treatments fail to provide relief. Surgery is usually only recommended for people with severe PCS who have not responded to other treatments.
