Multidisciplinary management of giant genital tract venous malformations during pregnancy: case report and review of the literature

Abstract

Abstract Malformation affecting the genital tract is a rare condition. Enlargement of the mass and specific complications may occur following hemodynamic changes associated with pregnancy. A 25-year-old pregnant primigravida affected by an extended vulvar and thigh venous malformation with localised intravascular consumptive coagulopathy was referred to our hospital. Her antenatal care was uneventful until term. She underwent an elective caesarean section because the venous malformation location precluded vaginal birth. At 3 days postpartum, she suffered life-threatening bleeding in the abdominal cavity with disseminated intravascular coagulation requiring multiple blood and platelets transfusions as well as transarterial embolisation. The patient recovered and was discharged after 20 days. Specific counselling and management of pregnant patients with large vascular malformations is essential as it is associated with increased complications rate such as peripartal thrombosis and haemorrhages. These patients should be referred to tertiary centres and should be managed by a multidisciplinary team including an obstetrician, anaesthesiologist, haematologist, interventional radiologist and plastic surgeon.
