Subsequent pregnancy outcome after previous foetal death

Area of Science:

• Perinatal Medicine
• Reproductive Health
• Obstetrics

Background:

• A prior fetal death is a significant risk factor for adverse outcomes in subsequent pregnancies.
• Persistent risk factors and potential recurrence of underlying causes contribute to this increased risk.

Purpose of the Study:

• To evaluate pregnancy outcomes following a fetal death.
• To compare cases of recurrent fetal death.

Main Methods:

• Retrospective cohort study of 163 women with a stillbirth after 16 weeks gestation.
• Medical records were reviewed for clinical, medical, obstetric, and pediatric data of the subsequent pregnancy.
• Causes of fetal death and recurrent fetal death were classified using the Tulip classification.

Main Results:

• Recurrent fetal death occurred in 11 cases, with identified causes in seven.
• An association between the index fetal death and subsequent fetal death was observed in some instances.
• This association was particularly noted in pregnancies occurring in early gestation.

Conclusions:

• Classifying the cause of recurrent fetal death and associated risk factors is crucial.
• Standardized classification provides insight into pathophysiological pathways of fetal death.
• This understanding is essential for developing effective preventive strategies to reduce fetal death recurrence.
