Abnormal umbilical cord insertions in singleton deliveries: placental histology and neonatal outcomes.

Aims: This study aimed to identify any microscopic features associated with abnormal (membranous/velamentous or marginal) placental cord insertions and to analyse their adverse neonatal outcomes.

Methods: We retrospectively analysed the records-including pathological findings, clinical information and pregnancy outcomes-for 1060 singleton pregnancies, involving newborn delivered after 24 weeks of gestation.

Results: Marginal cord insertions were identified in 26.
