Fetal Valproate Syndrome - Still a Problem Today!

Fetal exposition to valproate can lead to a cluster of facial dysmorphism, congenital anomalies and neurodevelopmental retardation. In this report we describe 2 cases of fetal valproate syndrome. In the first case, the gravida had a valproate medication before and during pregnancy with additional folic acid. She delivered a male premature infant at 25+2 weeks of gestation due to preterm labor and rupture of the membranes. Physical examination showed even in the premature infant typical signs of fetal valproate syndrome with trigonocephaly, epicanthal folds, broad root of the nose, low-set ears, thin upper lip and anteverted nares. In the second case, the gravida was under antiepileptic therapy with valproate and lamotrigine before and during pregnancy without any prophylaxis with folic acid. Sonographic examination during pregnancy diagnosed a spina bifida, Chiari II malformation and clubfeet. A female newborn was delivered at 39+4 weeks of gestation. Besides the prenatally detected anomalies, facial dysmorphism including microcephaly, low-set ears, thin upper lip and shallow philtrum were seen after birth. Valproate, a widely used anticonvulsant medication, is known for its teratogenic effects. The risk of congenital anomalies is even higher in combination with other antiepileptic drugs. Therefore, the avoidance of valproate or at least supplementation with a high dose prophylactic folic acid before and during pregnancy is highly recommended for women with epilepsy.
