OBJECTIVE: Destructive procedures to permit vaginal delivery of the fetus w
ith hydrocephalus are rarely performed.
STUDY DESIGN: We performed intrapartum cephalocentesis in 3 cases in which
alobar holoprosencephaly was diagnosed in the third trimester.
RESULTS: All 3 fetuses were stillborn. Two delivered vaginally, and one del
ivered abdominally with a lower uterine incision.
CONCLUSIONS: A reappraisal of the proper role of cephalocentesis in modern
obstetrics is offered.
