[Perinatal issues of biamniotic twin pregnancies depending on gestational ages of selective termination].

Objectives: A severe fetal abnormality is found in 1-2% of biamniotic twin gestations leading to the dilemma of expectative management or selective termination of the defective fetus. The primary objective of our study was to determinate the relationship between perinatal outcomes and gestational ages of selective termination.

Methods: We conducted a single-center retrospective and observational study which reviewed 58 biamniotic twin pregnancies that underwent selective termination for discordant fetal anomalies between January 2006 and September 2017.

[Per-partum risk factors of neonatal acidemia in planned vaginal delivery for fetuses in breech presentation].

Objectives: Delivery mode of term breech presentation is debated because of higher rate of neonatal acidosis (pH<7.15) in planned vaginal delivery than in planned caesarean section. The objective was to evaluate per-partum risk factors of neonatal acidosis in vaginal delivery for podalic fetuses.
