Pelvic Varices
Pelvic varices are enlarged, dilated veins within the pelvis, similar to varicose veins that occur in the legs. They are often associated with pelvic congestion syndrome, a condition that can cause chronic pelvic pain, fullness, or discomfort—especially when standing for long periods. Pelvic varices may also be found incidentally during imaging done for unrelated reasons.
What is it?
Pelvic varices occur when veins in the pelvis become enlarged or twisted, often due to backward flow of blood (venous reflux) or increased pressure in pelvic veins. These changes may be related to hormonal influences, valve dysfunction in the veins, pregnancy, or anatomical variations.
Imaging—especially CT or MRI—can show dilated pelvic veins and identify related findings such as ovarian vein enlargement. Ultrasound may help evaluate blood flow and detect venous reflux. When symptoms are significant, venography may be used for precise mapping and to plan treatment.
Important to Know
Pelvic varices alone are not dangerous, but they can contribute to chronic pelvic pain or discomfort. Many people with pelvic varices have no symptoms and need no treatment. For those with pelvic congestion syndrome, treatment options such as vein embolization can help reduce symptoms.
Red flag symptoms include sudden severe pelvic pain, fever, swelling of the legs, or signs of a blood clot—these are not typical of pelvic varices and require urgent evaluation. Persistent pelvic pain should be assessed to determine whether varices or another condition is the cause.
