PURPOSE:

To analyze fetal cerebral malformations with late termination of pregnancy (TOP) and to evaluate the rate of cases that could have been detected earlier using international recommended requirements of sonographic examination of the fetal central nervous system (CNS). MATERIALS AND

METHODS:

Cases of singleton pregnancies above 18 + 0 weeks of gestation ending in late TOP due to fetal CNS malformations between 2002 and 2011 were retrospectively reviewed. The cases were divided into isolated and non-isolated cerebral malformations. Prevalence and timing of TOP were assessed relative to the identified malformations.

RESULTS:

During this 10-year period, 212 (20.8%) out of 1017 late TOPs were performed in pregnancies with fetal cerebral malformations. 59 cases were excluded because of chromosomal anomalies. 86 (56.2%) of the remaining 153 cases were isolated cerebral malformations while 67 (43.8%) were non-isolated. TOP after viability (≥ 24 + 0 weeks of gestation) was performed in 61.4% (94/153). Substantial morbidity (n = 80; 52.3%) and mental retardation (n = 33, 38.4%) made up the leading prognostic groups. In about 80% of detectable anomalies, diagnosis of CNS malformation could have been made earlier by following international guidelines of fetal CNS examination at second trimester scan.

CONCLUSION:

General implementation of ultrasound screening in maternity care can significantly reduce the number of late TOPs in Germany.
