Making the correct diagnosis and prognostic counseling a33re complex. The aim of this study was to analyze pregnancy outcomes with regard to specific malformations, the factors which affect decision-making, and the time between diagnosis and termination as well as the causes of late diagnosis and late termination.<\/jats:p>\n                  <jats:p>A retrospective examination was carried out of all pregnancies with fetal CNS malformations treated at a perinatal center between 2003 and 2014. Termination rates, type of malformation, and gestational age at initial diagnosis and at termination were recorded. The factors influencing decision-making and the time between diagnosis and termination were analyzed statistically. A case-by-case analysis was carried out of any terminations performed after week 26+0 of gestation.<\/jats:p>\n                  <jats:p>In 139 of 251 cases (55.44%), the pregnancy was terminated between week 13+1 and week 38+2 of gestation (median: 22+4\u00a0GW). The median time from the initial diagnosis to the start of termination (\u0394termination) was 10 days (range: 1 to 94 days). Relevant factors influencing the decision to terminate the pregnancy were the type of malformation compared to isolated ventriculomegaly (non-isolated ACC [aOR 17.5; p\u00a0&lt;\u00a00.001], holoprosencephaly [aOR 24.4; p\u00a0&lt;\u00a00.001], spina bifida [aOR 7.24; p\u00a0&lt;\u00a00.001], other neural tube defects [aOR 62.5; p\u00a0&lt;\u00a00.001]) and the presence of additional genetic anomalies (aOR 6.38; p\u00a0=\u00a00.014). The decision to terminate the pregnancy occurred less often when the diagnosis was made at or after week 22+0 of gestation (aOR 0.24; p\u00a0&lt;\u00a00.001). Significant factors which affected the time between diagnosis and the start of termination (\u0394termination) were: having a fetal MRI (HR 0.41; p\u00a0=\u00a00.003) and maternal age (HR 0.95 per additional year; p\u00a0=\u00a00.034). The interval between diagnosis and termination was significantly shorter if a destructive abnormality (HR 10.5; p\u00a0=\u00a00.004) or a (non-spina bifida) neural tube defect (HR 3.86; p\u00a0=\u00a00.002) was present. A known chromosomal aberration (p\u00a0=\u00a00.87), non-CNS anomalies (p\u00a0=\u00a00.58), or a diagnosis \u2265\u00a022+0\u00a0GW (p\u00a0=\u00a00.74) affected the time between diagnosis and termination. The analysis of particularly late terminations from week 26+0 of gestation onwards found that avoidable delays in making the diagnosis or terminating the pregnancy only occurred in a few individual cases.<\/jats:p>\n                  <jats:p>The diagnostic and prognostic complexity of cerebral malformations means that delayed diagnosis and prolonged decision-making are common, even under optimal conditions of care. Early introduction of standardized prenatal diagnostic examinations is needed for to ensure that the pregnant woman receives open-ended, informed counseling as soon as possible. But late termination of pregnancy is not necessarily negative as, in most cases, this is due to the need for a differentiated prenatal diagnostic evaluation \u2013 for example, a fetal MRI \u2013 and the ethical requirement of sufficient time to provide informed, well-considered decision-making.<\/jats:p>","DOI":"10.1055\/a-2641-7664","type":"journal-article","created":{"date-parts":[[2025,9,2]],"date-time":"2025-09-02T23:12:50Z","timestamp":1756854770000},"page":"1203-1214","source":"Crossref","is-referenced-by-count":1,"title":["Management
