Ventriculoperitoneal shunt malfunction during pregnancy.

Many women with cerebrospinal fluid shunts are now reaching reproductive age. Shunt malfunction may occur during pregnancy, and management requires a well-planned, combined neurosurgical and obstetrical approach. We present a case of ventriculoperitoneal shunt obstruction manifesting during the third trimester managed successfully in a conservative fashion. The literature on ventriculoperitoneal shunt malfunction during pregnancy is reviewed.
