You’ve been dealing with a dull ache in your pelvis for months. Maybe it worsens after standing all day, during your period, or after intimacy. You may also notice pressure, heaviness, lower back discomfort, or even visible veins around your thighs or pelvis. Despite seeing multiple providers, you still may not have clear answers.
At St. Louis Vascular Surgical Specialists, PC, our vascular specialists help patients throughout the St. Louis area identify overlooked vein conditions, such as pelvic congestion syndrome. Understanding the cause of your symptoms is often the first step toward finding relief.
What exactly is pelvic congestion syndrome?
Pelvic congestion syndrome (PCS) is a chronic condition caused by enlarged, dysfunctional veins in the pelvis. It works similarly to varicose veins in your legs.
Normally, veins contain one-way valves that help blood return to the heart. When these valves weaken, blood flows backward and pools inside the veins. Over time, this pressure stretches the pelvic veins and causes chronic inflammation, pressure, and pain. PCS most commonly affects women during their reproductive years, especially after multiple pregnancies.
The pain is often described as a deep, aching sensation rather than a sharp pain. Many women also notice worsening symptoms at the end of the day because gravity increases pressure inside the damaged veins.
What symptoms should you watch for?
PCS symptoms can vary, which is one reason the condition is often misdiagnosed. The most common symptom is chronic pelvic pain lasting longer than six months.
You may also experience:
- A feeling of heaviness or fullness in the pelvis
- Pain that worsens after standing or sitting for long periods
- Discomfort during or after sexual intercourse
- Increased pelvic pain before or during menstruation
- Lower back or hip pain
- Visible varicose veins around the vulva, buttocks, or upper thighs
Many women describe it as a “dragging” feeling deep in the lower abdomen. Symptoms often become more noticeable later in the day because blood continues pooling in the pelvic veins.
What causes pelvic congestion syndrome?
Several factors can contribute to PCS. Hormones play a major role, particularly estrogen, which can weaken vein walls and make veins more likely to stretch.
Pregnancy is another major factor. During pregnancy, blood volume increases, and the growing uterus places pressure on pelvic veins. Multiple pregnancies can permanently damage the vein valves over time. Some women also develop PCS because of anatomical vein abnormalities that interfere with normal blood flow.
How is pelvic congestion syndrome diagnosed?
PCS can be difficult to diagnose because its symptoms overlap with gynecologic, gastrointestinal, and urinary conditions. That’s why vascular evaluation is so important.
At St. Louis Vascular Surgical Specialists, PC, diagnosis often begins with a detailed discussion about your symptoms, medical history, and pregnancy history. Imaging studies are then used to evaluate blood flow and identify enlarged pelvic veins.
These tests may include:
- Pelvic ultrasound
- CT scan
- MRI
- Venography
Venography is considered one of the most accurate diagnostic tools because it directly visualizes blood flow inside the pelvic veins.
Does pelvic congestion syndrome require surgery?
Not usually. Most patients can be treated with minimally invasive procedures rather than traditional surgery. One of the most effective treatments is ovarian vein embolization. During this image-guided procedure, a small catheter is inserted into the affected vein. Tiny coils or medical agents are then used to close the damaged vein and reroute blood through healthier veins.
Because the procedure is minimally invasive, recovery is typically much easier than surgery. Many patients experience significant symptom improvement within weeks. Lifestyle changes, compression garments, exercise, and hormonal management may also help reduce symptoms.
