Symptoms
What might you notice?
Vulvar varicosities may appear as blue or purple, curved or prominent veins around the vulva. Some people describe local swelling, heaviness, pressure or discomfort, particularly after prolonged standing. Others notice the veins without significant pain.
Groin, perineal, upper-thigh or leg varicose veins may be present at the same time. Coexistence does not necessarily mean that every vein has the same source.
Possible sources
Why do vulvar varicosities develop?
Vulvar veins may communicate with local veins, lower-extremity veins or the pelvic venous system. During pregnancy, changes in blood volume, hormones and pressure from the uterus can also make these veins more prominent.
Some vulvar varicosities are associated with pelvic venous reflux, while others are predominantly local or related to leg-vein pathways. Appearance alone cannot establish the source.
Clarifying terms
Vulvar varicosities are not the same as PCS
Pelvic Congestion Syndrome is traditionally used for a chronic pelvic pain presentation associated with pelvic venous abnormalities. Vulvar varicosities can occur without pelvic pain and do not by themselves indicate a need for pelvic vein embolization or another pelvic intervention.
Management should be based on symptoms, the venous source, ultrasound findings and individual priorities, rather than appearance or a label alone.
Assessment
What does assessment involve?
Assessment begins with when the veins appeared, their relationship to pregnancy or standing, associated leg or pelvic symptoms and any previous venous treatment. Standing examination and lower-extremity duplex ultrasound can assess leg reflux, groin veins and possible communicating pathways.
If veins near the groin, perineum or vulva need to be assessed, the purpose and extent of the examination will be explained first. Examination proceeds only with consent, with attention to privacy and comfort wherever possible.
Further evaluation
When might further pelvic evaluation be considered?
Further evaluation may be appropriate when the pattern is extensive, bilateral or complex, or when local groin or vulvar venous findings do not adequately explain the overall distribution or symptoms.
Referral can then be arranged for the most appropriate specialist or hospital imaging. Not every person with vulvar varicosities requires CT, MR, transvaginal ultrasound or catheter examination.
Care & treatment
Observation, conservative care and local treatment
Observation and symptom management may be sufficient when symptoms are mild and there is no urgent concern. During pregnancy, care is usually based on clinical assessment and conservative measures; elective venous intervention is not a routine strategy.
After the venous source has been assessed, Dr Liang may consider local sclerotherapy for selected local symptomatic vulvar or perineal veins. If pelvic vein embolization or venous stenting is considered necessary, referral is made to a hospital or appropriate specialist.
Postpartum changes
Will the veins improve after pregnancy?
Some pregnancy-related vulvar veins improve after delivery, but the degree and timing vary. Complete spontaneous resolution cannot be promised. If symptoms persist, reassessment is often appropriate at around three to six months postpartum. Acute or severe symptoms should be assessed earlier.
Clinical guidance
When to seek prompt medical assessment
Seek prompt medical assessment for a rapidly enlarging and very painful local lump, significant or persistent bleeding, local pain and swelling with fever or signs of infection, or sudden marked swelling, pain, redness or warmth in one leg. Sudden breathlessness, chest pain, coughing up blood, fainting or significant breathing difficulty requires immediate emergency-department care; call 119 if the situation is critical. During pregnancy, rapidly worsening or severe pelvic or abdominal pain, significant bleeding, fever or another acute symptom should receive priority obstetric or emergency assessment.
