In approximately 2000 - 2500 (25 - 30%) of those iufants, the malformation will be either lethal or will lead to severe physi cal and/or mental handicaps. The largest category ofmalformations concerns anomalies as a result ofa combination ofenvironmental and hereditary factors, such as spina bifid a and congenital heart problems. In the Netherlands pregnant women with a known increased risk of a fetal abnor mality, for instance advanced maternal age, a previously affected child, or being a known carrier of a genetic abnormality, are eligible for prenatal diagnosis. This is also the case when fetal problems are discovered dnring a basic ultrasound scan, such as severe growth retardation or polyhydramnion. A considerable number of severe or lethal fetal malformations are diagnosed during the second half of pregn~ncy, sometimes at 24 weeks or later. In the Netherlands, the legal upper limit for pregnancy termination is 24 weeks. At this stage of pregnancy ma ternal-fetal bonding, the unexpected emotional trauma of carrying an infant with a se vere anomaly and the fact that pregnancy termination beyond 24 weeks is generally illegal, might enhance the psychological burden ofthe bad news about the unborn baby. This chapter deals with the present knowledge on prenatal diagnosis, particularly anomaly scanning, its psychological impact on women and specific problems related to late (threatened) pregnancy loss. Furthermore, perinatal grief and its theoretical frame work which provides the background for this study, are introduced. A short review is given regarding the determinants of perinatal grief, views on normal versus abnormal grief, and methodological issues in perinatal grief research. Finally, a compilation ofthe research objectives that will be addressed, is presented. 1.2 Prenatal diagnosis The tests used in prenatal diagnosis are designed to detect genetic diseases or defects in the unborn iufant. The four most important prenatal procedures are: chorionic villus sampling, amniocentesis, cordocentesis, and tertiary centre ultrasonography. A specific test in prenatal diagnosis which is still very much under scrutiny is the maternal serum alpha-fetoprotein test (MSAFP-test). Chorionic villus sampling (CVS) is used to detect genetic defects in the first tri mester of pregnancy (9-12 weeks). Fetal cells are extracted from chorionic villi. These are protrusions of a membrane (the chorion) that surrounds the developing unborn infant. The procednre is carried out through a thin tube via the cervix or by a needle inserted into the maternal abdomen, under ultrasound guidance. The collected cells undergo chromosomal, DNA or biochemical analysis for the detection of specific ge- 2 Chapter 1 netic diseases such as Down's syndrome. Results are available within 8-10 days. Experi enced centres generally quote a one per cent fetal loss rate following CVS (De Crespigny and Dredge, 1991). Amniocentesis is the most widely used technique in the second trimester of gesta tion (between 15-17 weeks). A needle is inserted under ultrasound guidance through the maternal abdomen into the amniotic sac that surrounds the unborn child. A small amount of amniotic fluid containing fetal cells is extracted and cultured. Cells and fluid are then analyzed for genetic abnormalities, such as Down's syndrome or neural tube defects, including anencephaly and spina bifida. Results are available after 2-3 weeks. The fetal loss rate is 0.3-0.5%. Cordocentesis entails blood sampling from the umbilical vein. The procedure is similar to that for CVS and amniocentesis. Adequate fetal blood sampling is possible from 19-20 weeks of gestation. It is often used following the detection of fetal anoma lies in late pregnancy, since chromosome results are available as soon as 72 hours. In ultrasonography structural disorders such as neural tube defects, central nerv ous system anomalies, skeletal, kidney and urinary tract disorders can be assessed. The accuracy depends on the experience and skill ofthe investigator, the type of equipment and fetal age.
