title: Medical and Ethical Considerations Related to Viable Fetuses with Trisomy 13 in the 36th Week of Pregnancy--a Review of the Literature.
abstract: Patau syndrome was first described in 1960 as a group of birth defects caused by trisomy of chromosome 13 (T13). Providing accurate information and relevant reproductive genetic counseling that would allow parents to make informed decisions is not easily accomplished because of the limited information available prenatally. Only 1/3 of all cases of T13 are diagnosed prenatally, which means it cannot be expected that most cases will be detected early in pregnancy, that the parents will decide to terminate the pregnancy, and that difficulties will be avoided. There is no good prenatal screening for T13, and there are many kinds and degrees of anomalies. About 60% of cases are first detected in the second trimester, and life expectancy is difficult to predict. When patients choose not to terminate pregnancy, or when the pregnancy has progressed to a viable gestational age, pregnancy termination is no longer an option. Also, nowadays 12% of couples choose to continue pregnancy following chromosomal confirmation of a suspected T13. The aim of this work is to eludicate for health care providers what problems they are likely to face in the care of children with T13 and in contact with their parents. It is crucial for the management of each case to discuss neonatal procedures of resuscitation, alternatives to aggressive resuscitation, the possibilities for correcting some of the defects, and to be prepared to guide the parents through the trauma of having a child with a lethal defect.
