[Embryofetopathy due to valproate: a pathology only little known. Apropos of 4 cases].

BACKGROUND

Sodium valproate administration during pregnancy may be teratogenic; it is associated with an increased risk of neural tube defect, tetralogy of Fallot, oral clefting and other facial abnormalities. Knowledge of these harmful effects is still poor.

CASE REPORTS: Four children, including three siblings, presented with characteristic facial abnormalities (four cases), oral clefting (one case), mental retardation (2/2 cases), and bone anomalies of forearm and hands (one case). The diagnosis of fetal valproate syndrome was only made at the age of 3 1/2 years in the eldest of the three siblings all born from an epileptic mother receiving valproate since the age of 13 years. Prevention advice for further pregnancies was not followed.

CONCLUSION

All epileptic mothers should be aware of the risk of antiepileptic drugs during pregnancy, specially those given sodium valproate, a potentially teratogenic drug.
