N2 - Purpose: To assess fetal central nervous system (CNS) abnormalities presenting as major findings leading to late termination of pregnancy (late TOP) performed ≥ 24 weeks’ gestation. Method: The study population included 2789 pregnant women that underwent late TOP in our institute between the years 1998 and 2015. Results: Fifty-seven cases (2.0%) underwent late TOP because of fetal CNS indications and are the subjects of the current study. Those cases were subdivided into four categories (1) no routine prenatal screening with an incidental finding discovered ≥ 24 weeks’ gestation (25 patients, 43.8%); (2) developmental or acquired findings detected during late second and third trimester (22 patients, 38.6%); (3) apparently normal routine screening with abnormal findings that could have been detected earlier (six patients, 10.6%); (4) routine prenatal care raised suspicion of abnormalities, and the final diagnosis was established only following additional tests (four patients, 7.0%). Conclusions: Combining the two categories of CNS abnormalities, i.e., pregnant women who did not undergo any fetal evaluation (group 1) and those that could have been detected earlier (group 3) consists 54% from our cohort in which late TOP could have been avoided. On contrary, 39% fetuses from our study population had CNS developmental findings which could be detected only at advanced stage of gestation.
