Abstract
Background
In early terminations of pregnancy for fetal anomaly (TOPFA) without identified cytogenetic abnormality, a fetal autopsy is recommended for diagnostic purposes, to guide genetic counseling. Medical induction, which allows analysis of a complete fetus, is generally preferred over surgical vacuum aspiration. Our objective was to assess the diagnostic value of fetal autopsies in these early terminations, relative to the first-trimester ultrasound, overall and by termination method.
Materials
For this retrospective study at the Port Royal Maternity Hospital, we identified all TOPFA performed from 11 weeks to 16 weeks diagnosed at the first-trimester ultrasound in cases with a normal karyotype. The principal endpoint was the additional value of the autopsy over /compared to the ultrasound and its impact on genetic counseling, globally and by termination method. The secondary objective was to compare the complication rate by method of termination.
Results
The study included 79 women during period of 2013–2017: 42 with terminations by medical induction and 37 by aspiration. Fetal autopsy found additional abnormalities in 54.4% of cases, more frequently after medical induction (77.5%) than after aspiration (21.4%, p < .01). Genetic counseling was modified in 20.6% of cases, more often after induction (32.5% vs 3.6%, p < .01). The length of stay was significantly longer and a secondary aspiration was required in 16,7% of case in the medical induction group (p < .01).
Conclusion
Medically induced vaginal expulsion appears preferable and can change genetic counseling for subsequent pregnancies.
