Pelvic congestion syndrome (also known as pelvic vein incompetence) is a chronic medical condition in women caused by varicose veins in the lower abdomen. The condition causes chronic pain, often manifesting as a constant dull ache, which can be aggravated by standing.[1] Early treatment options include pain medication and suppression of ovarian function. Surgery can be done using noninvasive transcatheter techniques to embolize the varicose veins.[1] Up to 80% of women obtain relief using this method.

The condition can occur as a result of pregnancy or for unknown reasons.[2] The presence of estrogen in the body causes vasodilation, which can result in the accumulation of blood in the veins in the pelvic area.[3] Estrogen can weaken the vein walls, leading to the changes that cause varicosities.[2] Up to 15% of all women have varicose veins in the abdominal area, but not all have symptoms.[3]

Signs and symptoms[edit]

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 sufferers 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.[2][3]

Women with pelvic congestion syndrome have a larger uterus and a thicker endometrium. 56% of women manifest cystic changes to the ovaries,[4] and many report other symptoms, such as dysmenorrhea, back pain, vaginal discharge, abdominal bloating, mood swings or depression, and fatigue.[2][3]

  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 [5]

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.[2][3] Recent research from a leading pelvic venous unit has suggested that Transvaginal Duplex Ultrasound scanning is the "Gold Standard" test for pelvic venous reflux.[6] The same research group has shown that the size of the veins - as shown by venography and also used as the diagnostic criteria in CT and MRI - is not relevant and only Transvaginal Duplex Ultrasound shows the venous reflux that causes the problem.[7]


Early treatment options include pain medication using nonsteroidal anti-inflammatory drugs,[3] suppression of ovarian function,[4] and alternative therapies such as physical therapy.[2]

The surgical option involves stopping blood flow to the varicose veins using noninvasive surgical techniques such as a procedure called embolization. The procedure requires an overnight stay in hospital, and is done using local anesthetic.[2][8] Patients report an 80% success rate, as measured by the amount of pain reduction experienced.[8]
