Severe Fetal Abnormality and Outcomes of Continued Pregnancies: A French Multicenter Retrospective Study.

Objectives To describe a population choosing to continue with their pregnancy despite being eligible to receive a medical termination of pregnancy (TOP). Methods Nine-year retrospective study of data (01/01/2006 to 31/12/2014) from three French prenatal diagnostic centers describing the perinatal outcomes of these pregnancies. Pregnancies were classified according to etiology and severity of its fetal pathology. Several perinatal parameters were described: maternal characteristics, parental prenatal choices and information on the pregnancy and neonatal outcomes. These parameters were classified in function of the severity of fetal pathology according to the classification proposed by Dommergues et al. (Prenatal Diagnosis 30(6):531-539, 2010) Results Overall, 155 pregnancies were continued; 140 have been included in our study. Pregnancy outcomes consisted of four TOPs (2.9%); 20 in utero deaths (14.3%); 110 live births (78.6%) of which 55.4% were still alive at 2 years old as the most recent information; and 6 (4.2%) with unknown outcomes. In 27 cases, perinatal palliative care was requested (an increase of 37% over 9 years). 36.4% of cases were classified as having a high mortality risk; 19.3% with a severe handicap risk; 11.4% with a risk of isolated intellectual disability; and 32.9% with an uncertain prognosis. The parental decisions to choose perinatal palliative care were significantly higher within the high mortality risk group as compared to other severity groups (p < 0.001); this group also had a significantly higher mortality (p < 0.001), with a survival rate of 26.3%. Conclusion Over the study period, in France, there was an increase in continued pregnancies, despite a diagnosis of severe fetal pathology in France. Therefore, it is essential that perinatal professionals are provided with a palliative care framework and training in their approach for this population which is heterogeneous in terms of etiology.
