Survival in infants with anencephaly.

There is little available literature on survival data in the form of lifetables for babies born with anencephaly. These data would be valuable in advising parents, who often request very specific information on the length of time their child might survive. Survival is examined for a cohort of anencephalic infants in a well-defined population. Sex-specific survival tables are given, since these are the most practical to use for counselling purposes. These data show that over 40 percent of liveborn anencephalic infants (51% males; 34% females) survive longer than 24 hours, and of these, 5 percent are still alive on the seventh day. Data also are presented on the types of malformations observed in addition to anencephaly.
