Frequency30% of women presenting complaints of chronic pelvic pain [6]
DeathsRare

Pelvic congestion syndrome, also known as pelvic vein incompetence, is a long-term condition believed to be due to enlarged veins in the lower abdomen. [1] [7] The condition may cause chronic pain, such as a constant dull ache, which can be worsened by standing or sex. [1] Pain in the legs or lower back may also occur. [1]

Contents

While the condition is believed to be due to blood flowing back into pelvic veins as a result of faulty valves in the veins, this hypothesis is not certain. [7] The condition may occur or worsen during pregnancy. [1] The presence of estrogen is believed to be involved in the mechanism. [1] Diagnosis may be supported by ultrasound, CT scan, MRI, or laparoscopy. [1]

Early treatment options include medroxyprogesterone or nonsteroidal anti-inflammatory drugs (NSAIDs). [1] Surgery to block the varicose veins may also be done. [1] About 30% of women of reproductive age reporting pelvic pain are affected. [6] It is believed to be the cause of about a third of chronic pelvic pain cases. [5] While pelvic venous insufficiency was identified in the 1850s it was only linked with pelvic pain in the 1940s. [5]

Signs and symptoms

Women with this condition experience a constant pain that may be dull and aching, but is occasionally more acute. The pain is worse at the end of the day and after long periods of standing, and those affected get relief when they lie down. The pain is worse during or after sexual intercourse, and can be worse just before the onset of the menstrual period. [8]

Women with pelvic congestion syndrome have a larger uterus and a thicker endometrium. 56% of women manifest cystic changes to the ovaries, [9] and many report other symptoms, such as dysmenorrhea, back pain, vaginal discharge, abdominal bloating, mood swings or depression, and fatigue. [8]

Causes

  1. Local pelvic hormonal milieu
  2. Venous outflow obstruction, such as May-Thurner syndrome, Nutcracker syndrome, Budd-Chiari syndrome, or left renal vein thrombosis
  3. External compression due to tumor (including fibroids, endometriosis), or scarring [10]

Diagnosis can be made using ultrasound or laparoscopy testing. The condition can also be diagnosed with a venogram, CT scan, or an MRI. Ultrasound is the diagnostic tool most commonly used. [8] Some research has suggested that transvaginal duplex ultrasound is the best test for pelvic venous reflux. [11]

Treatment

Early treatment options include pain medication using nonsteroidal anti-inflammatory drugs, [8] and suppression of ovarian function. [9]

More advanced treatment includes a minimally invasive procedure performed by an Interventional Radiologist. This minimally invasive procedure involves stopping blood within the pelvic varicose veins using a minimally invasive procedure called a catheter directed embolization. The procedure rarely requires an overnight stay in hospital and is usually performed as an outpatient procedure, and is done using local anesthetic and moderate sedation. [4] Patients report an 80% success rate, as measured by the amount of pain reduction experienced. [4]
