During pregnancy, a cerebrospinal fluid (CSF) shunt operation may be necessary due to hydrocephalus. Although many authors have suggested that pregnancy in a patient with a ventriculoperitoneal (VP) shunt for maternal hydrocephalus. generally has anormal outcome. VP shunt malfunctions appear to be common in pregnancy due to increased intraperitoneal pressure. In this paper, we present a pregnant woman with hydrocephalus who required multiple revisions of a VP shunt. We consider that when a pregnant woman develops hydrocephalus requiring shunting, a ventriculoatrial (VA) shunt should be preferred.
