Pelvic Congestion Syndrome
Pelvic Congestion Syndrome is a vascular condition caused by enlarged, poorly functioning veins in the pelvis. It is a recognised and treatable cause of chronic pelvic pain particularly in women and is often mistaken for gynaecological or musculoskeletal problems. With the right diagnosis and minimally invasive treatment, lasting relief is possible.

What Is Pelvic Congestion Syndrome?
Pelvic Congestion Syndrome occurs when the veins in the pelvis, most commonly the ovarian veins and pelvic plexus, become dilated and fail to drain blood efficiently. Much like varicose veins in the legs, these engorged pelvic veins allow blood to pool, creating sustained pressure and chronic pain.
Think of it like varicose veins, but deep inside the pelvis and invisible on the surface, but very real in terms of the discomfort they cause.
PCS is one of the most underdiagnosed causes of chronic pelvic pain. Many women spend years undergoing investigations or receiving treatments for gynaecological conditions, when the true culprit is vascular.
Why Does PCS Happen?
Several factors contribute to the development of pelvic varicose veins and PCS:
- Pregnancy – Multiple pregnancies significantly increase pelvic venous pressure, stretching and weakening vein walls over time.
- Hormonal Influence – Oestrogen is thought to relax and dilate vein walls, which may explain why PCS almost exclusively affects women of reproductive age.
- Anatomical Factors – The left ovarian vein drains at a more challenging angle, making it more prone to reflux and dilation.
- Family History – A genetic tendency toward vein weakness can increase risk.
- Nutcracker Syndrome – Compression of the left renal vein can elevate pressure in the ovarian vein, contributing to PCS.
Recognising the Signs: Could Your Pelvic Pain Be Vascular?
PCS is frequently missed because its symptoms overlap with many other conditions. Common presentations include:
- Dull, aching pelvic pain lasting longer than six months
- Pain that worsens after prolonged standing or sitting
- Pain that intensifies during or after sexual intercourse
- Pain that is worse during or after menstruation
- Heaviness or pressure in the lower abdomen or pelvis
- Visible varicose veins around the vulva, inner thighs, or buttocks
- Bladder urgency or irritable bowel symptoms linked to pelvic pressure
Pain that worsens as the day goes on, particularly after being on your feet and improves when lying down is a hallmark pattern of PCS. If this sounds familiar, a vascular evaluation may be the missing piece.
How I Diagnose PCS: A Specialist's Approach
Because PCS is a vascular condition, accurate diagnosis requires vascular expertise. At our clinic, diagnosis involves a thorough and structured assessment:
Clinical evaluation:
- A careful history of your pelvic pain: its character, triggers, and timing
- Review of previous investigations and treatments
- Assessment of associated vulvar or leg varicose veins
Imaging studies:
- Pelvic Duplex Ultrasound – A non-invasive first-line assessment to evaluate ovarian and pelvic vein diameter and detect reflux
- CT Venography (CTV) or MR Venography (MRV) – Detailed cross-sectional imaging to map out pelvic vein anatomy and identify compression syndromes
- Catheter-Based Venography – The gold-standard diagnostic test, performed as part of a combined diagnostic and treatment procedure when required
Treatment: Relieving Pressure, Restoring Comfort
PCS is a treatable condition. Most patients can achieve significant and lasting pain relief without open surgery. Treatment is personalised based on the severity of your symptoms and imaging findings.
Conservative Measures:
- Lifestyle Modifications – Avoiding prolonged standing, regular movement throughout the day, and leg elevation can reduce pelvic pressure.
- Supportive Compression – Graduated compression garments, particularly for associated vulvar or leg varicosities.
- Hormonal Therapy – Medications that reduce oestrogen stimulation of pelvic veins may be used as a short-term measure.
Minimally Invasive Interventional Treatment:
- Pelvic Vein Embolisation – The most effective treatment for PCS. A small catheter is guided through a vein in the neck or groin under X-ray guidance. The abnormal pelvic veins are then blocked using coils and/or a sclerosant agent, stopping blood from pooling. This is performed under local anaesthesia as a day procedure with minimal recovery time.
- Sclerotherapy of Pelvic Varicosities – Used alongside embolisation to treat accessory dilated pelvic veins.
- Treatment of Contributing Compression – If Nutcracker Syndrome or other anatomical compressions are identified, these can be addressed as part of the overall management plan.
Most patients experience a gradual improvement in pain over the weeks following embolisation, with the majority reporting meaningful long-term relief.
Empowering You to Take Control
Living with chronic pelvic pain can be isolating, especially when the cause has gone unrecognised. PCS is real, it is vascular, and it is treatable.
Practical steps that can help:
✅ Keep a pain diary noting when symptoms are worst (end of day, after standing, post-intercourse)
✅ Avoid prolonged standing without movement breaks
✅ Elevate your legs and hips when resting
✅ Share your full symptom history with your doctor including the pattern and triggers
✅ Ask specifically about a vascular assessment if your pelvic pain has not responded to other treatments
You Deserve a Diagnosis That Makes Sense
If you have been experiencing chronic pelvic pain and have not found answers through gynaecological investigations alone, a vascular assessment may finally provide the clarity and relief you have been looking for. I take a careful, evidence-based approach to ensure that nothing is missed and that your care is truly personalised.
