For many women, pelvic pain is an uncomfortable, frustrating part of their everyday life. This pain can be caused by pelvic venous congestion syndrome (PVCS), also known as pelvic venous disease.

In PCVS, the pain is felt below the belly button and can worsen during menstrual cycles or just after a long day of sitting or standing. PVCS often overlooked or can be difficult to diagnose because there are various other reasons that can cause pelvic pain.

PCVS occurs mostly in women who have experienced pregnancy or who have vein compression syndromes. In the pelvis, veins have one-way valves that help keep blood flowing toward to the heart. During pregnancy, ovarian and pelvic veins widen to accommodate the increased blood flow from the uterus. If the valves are weak or damaged, and the veins fail to return to their normal size after pregnancy, the blood backs up and the veins become “congested,” which can be painful. Other symptoms include pain on one or both sides of the pelvis, a feeling of “fullness” in the legs or incontinence due to the enlarged veins pressing the bladder or rectum.

If your doctor suspects you have PCVS, they will perform some tests to determine if the pain if caused by venous congestion. These can include pelvic or transvaginal ultrasound, an MRI or a CT scan. They might also perform a pelvic venogram, a test in which a special dye is injected into the veins so they will show up on an X-ray.
