Vulvar Varicose Veins: Causes, Risks, and Treatment Options

Vulvar varicose veins are enlarged veins that develop around the vaginal opening and external genital area. Although varicose veins are most commonly associated with the legs, changes in blood flow during pregnancy mean that veins within the pelvis and vulvar region can also be affected.

These veins develop as a result of venous reflux, in which blood does not return efficiently to the heart. Increased blood volume, pressure from the growing uterus and hormonal changes during pregnancy place additional strain on the venous system. As a result, veins in the vulvar region may enlarge, become more visible and cause discomfort.

In many cases, vulvar varicose veins improve after pregnancy. However, assessment is essential to confirm the diagnosis, exclude underlying pelvic venous reflux and provide appropriate advice or treatment where symptoms persist.

At Vein Solutions, vulvar varicosities are assessed in line with recognised venous disease pathways, with care guided by clinical examination and ultrasound findings.

Causes Of Vulvar Varicose Veins

Pregnancy Related Venous Changes

Pregnancy is the most common cause of vulvar varicose veins. Blood volume increases significantly to support the developing baby, while the expanding uterus places pressure on pelvic veins. These changes make it harder for blood to flow upwards against gravity.

Hormonal changes during pregnancy also relax vein walls, increasing the likelihood of valve dysfunction. This combination can lead to venous pooling and varicosities around the vulva.

Reassuringly, vulvar varicose veins do not usually interfere with vaginal delivery. Many reduce naturally after childbirth, although they may persist or recur with future pregnancies.

Pelvic Venous Reflux and Pelvic Congestion Syndrome

In some cases, vulvar varicose veins are linked to pelvic venous reflux, including pelvic congestion syndrome. This occurs when valves in the pelvic veins fail, allowing blood to pool and spread into surrounding veins.

Women who have had multiple pregnancies or vaginal deliveries are more likely to develop this pattern. Pelvic venous reflux may also be associated with leg varicose veins.

Genetic and Age Related Factors

A family history of venous disease increases susceptibility. Age-related changes in vein elasticity can also contribute, although vulvar varicosities are most frequently seen during childbearing years.

Other Contributing Factors

Prolonged standing can increase venous pressure, particularly during pregnancy. Rarely, vulvar varicosities may arise due to obstruction of venous drainage within the pelvis, which is why new or unusual symptoms should be assessed.

Symptoms and Clinical Features

Vulvar varicose veins may appear as swollen, bluish veins around the vulva. Symptoms often worsen later in the day, during prolonged standing or as pregnancy progresses.

Symptoms may include a feeling of pressure or fullness, aching, tenderness, itching or discomfort during intercourse. Some women have visible veins without significant symptoms.

Assessment and Diagnosis

NICE guidance on varicose veins recommends clinical assessment, supported by duplex ultrasound, when venous reflux is suspected. This principle applies equally to vulvar varicosities, particularly where symptoms persist or pelvic venous disease is suspected.

Clinical examination is often sufficient to identify vulvar varicose veins. Ultrasound imaging helps assess venous flow and identify reflux in pelvic or lower-limb veins. This ensures treatment decisions are based on vein function rather than appearance alone.

Management During Pregnancy

During pregnancy, treatment is usually conservative unless symptoms are severe. This approach aligns with NICE guidance, which supports symptom management and reassurance where appropriate.

Advice may include avoiding prolonged standing, engaging in gentle activity, elevating the legs when resting, and wearing supportive garments. Compression may be helpful in some cases, depending on symptoms and vein distribution.

Symptoms are monitored throughout pregnancy, with further assessment considered if veins persist after delivery.

Treatment Options After Pregnancy

If vulvar varicose veins persist following childbirth or cause ongoing symptoms, minimally invasive treatment may be considered.

Sclerotherapy

Sclerotherapy involves injecting a solution into the affected vein, causing it to close and gradually be absorbed. Foam sclerotherapy may be used for larger veins under ultrasound guidance.

Endovenous and Thermal Techniques

Laser or radiofrequency techniques may be appropriate where deeper refluxing veins contribute to vulvar varicosities. These treatments aim to close the underlying vein that is causing increased pressure.

Cyanoacrylate Glue Closure

Cyanoacrylate glue may be used in selected cases to seal veins without heat. Ultrasound findings and vein anatomy determine suitability.

Symptoms, ultrasound results, and the presence of pelvic venous reflux guide treatment choice.
