Termination of pregnancy for fetal neurological abnormalities.
BACKGROUND
Prenatal screening for fetal abnormalities may identify conditions likely to result in perinatal death or in survival with a risk of handicap, for which termination of pregnancy is legal in many countries.


CONCLUSIONS
When considering termination of pregnancy, it is crucial that prenatal diagnosis be as accurate as possible and that the prognosis of the condition diagnosed in utero is thoroughly understood by the parents. Our ability to predict postnatal outcome in borderline cases should not be overestimated. Parents should not precipitate their decision, and in some European countries, the absence of a gestational age limit at which a termination may be performed is viewed as a guarantee against hasty terminations. Maternal morbidity potentially associated with termination should be kept as low as possible. This includes maternal analgesia, and avoiding uterine trauma to preserve fertility and to prevent obstetrical complications in subsequent pregnancies. Bereavement should also be taken into account. Tests that could contribute to confirming the diagnosis or to establishing the aetiology of the abnormality, such as fetal karyotype or platelet count, should be implemented when appropriate, since post-termination genetic counselling relies on such data. Post-mortem examination is often crucial for genetic counselling and should include X-rays and gross examination of the fetus as well as brain and spine examination by a neuropathologist with expertise in the field of fetal medicine. Specific post-mortem procedures sometimes need to be planned before termination, for instance, in fetal akinesia sequence. First trimester surgical techniques and second or third trimester medical techniques of termination of pregnancy are reviewed.
