Chronic pelvic pain affects many women and diagnosing the exact cause can somtimes be difficult. Pelvic Congestion Syndrome (PCS) also referred to pelvic pain of venous origin is an under diagnosed but common cause of pelvic pain that is oftan treatable.

Chronic pelvic pain, defined as pain persisting in the pelvic region for more than six months, is a prevalent issue affecting a significant number of women. This pain can become a substantial disability, hindering daily activities and overall well-being. Diagnosing the root cause of chronic pelvic pain can be quite challenging due to the involvement of various underlying conditions.

Pelvic Congestion Syndrome: A Potential Source of Pelvic Discomfort

One potential culprit to consider in the evaluation of chronic pelvic pain is Pelvic Pain of Venous origin, also referred to as Pelvic Congestion Syndrome (PCS). This syndrome manifests with pain that often intensifies with prolonged sitting or standing, and finds relief when lying down. Women with PCS might also experience discomfort during urination (dysuria) or sexual activity (dyspareunia). The condition appears to be more frequent in women with a history of multiple pregnancies. It's believed that the hormonal fluctuations and weight gain associated with pregnancy contribute to the development of PCS by weakening vein walls and increasing pressure within the pelvic veins.

Unraveling the Mystery of PCS

While the exact cause of PCS remains unclear, there is a strong possibility that anatomical or hormonal abnormalities play a contributing role. The syndrome primarily affects women between the ages of 20 and 45 who have undergone multiple pregnancies.

The Telltale Signs of Pelvic Congestion Syndrome:

Pelvic Congestion Syndrome (PCS) can manifest in various ways, but some common signs and symptoms are more suggestive of this condition:

  • Pelvic and Lower Back Pain: Dull aching or dragging sensation in your pelvis or lower back might be a red flag, especially if it intensifies when you stand for long periods or worsens around your menstrual cycle.
  • Bladder Woes: Frequent urination or difficulty holding urine (stress incontinence) could be signs of PCS affecting your bladder.
  • Irritable Bowel: If you experience recurring abdominal pain, alternating between diarrhea and constipation, it could be related to PCS.
  • Painful Sex: Deep dyspareunia, or discomfort during or after sexual intercourse, can be a symptom of PCS.This often will last for a while after intercourse, sometimes till the next day.
  • Varicose Veins "Down There": Bulging veins around the vulva or vagina, along with varicose veins on the inner thighs or back of the thighs, are all potential signs of PCS.

Combating PCS: Exploring Treatment Options

Pelvic Congestion Syndrome (PCS) can be effectively treated with minimally invasive procedures. Here's a breakdown of the two main options:

  • Pelvic Venography and Embolization: This might sound complex, but it's a two-step approach that can be done together or separately. Pelvic venography is performed through a needle puncture into a vein through this access a long thin tube (catheter) is advanced under live X-Ray to the prlvis an injection of X-Ray contrast is performed to map out the malfunctioning veins. This information can then be used for embolization, which can be performed through the same tube. During embolization, sclerosing agents, which are basically like tiny irritants, are injected to close off the varicose veins. Additionally, small metal coils or plugs might be used to block blood flow to prevent it from recurring. This reduces pressure within the enlarged pelvic veins.
  • Here's the good news: embolization doesn't affect fertility or blood flow to the uterus or ovaries because there are naturally multiple veins in that area. If needed, other problematic veins can be addressed with additional embolization procedures. This is typically done on an outpatient basis, meaning you can go home after a few hours and resume normal activities quickly. Studies show that the majority of patients experience symptom improvement after embolization, though in select cases, multiple sessions might be required to treat all affected veins.

Potential Side Effects of Treatment

Pelvic venography and embolization is considered a safe non-surgical procedure with a very low complication rate. As with any procedure, however, it's always wise to be aware of potential side effects. The best way to manage any concerns is to discuss them openly beforehand. Here's a breakdown of some possible occurrences:

  • Minor Bruising: A hematoma, or bruise, might appear around the puncture site where the catheter was inserted. This is usually temporary and fades within a few days or a week.
  • Allergic Reactions: In rare cases, some patients experience allergic reactions to the contrast dye used during venography. If you have a history of allergies, be sure to mention it to your doctor. Signs of an allergic reaction include difficulty breathing, itching, rash, or hives. Let your doctor know immediately if you experience any of these symptoms.
  • Temporary Kidney Issues: For individuals already at risk for kidney problems due to pre-existing conditions or medications, there's a slight possibility of a temporary increase in creatinine levels following the procedure. For patients without prior kidney problems, these issues would be exceedingly rare.
  • Coil Movement: The small metal coils or plugs used during embolization are typically placed to prevent blood flow reversal. Very rarely, these coils might shift out of position and travel from the intended vein. If properly and carefully placed this should not happen. If it does these usually can be removed from the same access.
  • Vein injury: While uncommon, there's a small risk of injuring a vein during the procedure which is usually self-limiting.

Expertise in Treating PCS

Given the complexities involved in PCS, recognition of this condition as well as a physician experienced in the nuances of this condition is paramount to successful treatment and achieving the best results.
