VP36.21: Timing of delivery in twin pregnancy with selective fetal growth restriction

In compromised fetal growth restriction (FGR), the decision on optimal timing of delivery is made based on the risk of intrauterine death (IUD) and the risk of iatrogenic preterm birth (PTB). In twin pregnancy, if selective FGR (sFGR) twin is in the status of impending IUD in preterm, immediate delivery will reduce the risk of IUD while exposing co-twin to PTB. The objective of this study was to evaluate the physician's views on the optimal timing of delivery in sFGR twin. The online questionnaires were sent to obstetricians and gynecologists (OBGYN) in South Korea. The questionnaire asked 1) the limit of viability and the limit of intact survival; 2) the optimal timing of delivery in dichorionic (DC) and monochorionic (MC) twin pregnancy if the sFGR twin is suspected as the status of impending IUD. Participants tend to deliver compromised sFGR twin at GA of the limit of intact survival (30 wks) in DC twin and at the midway between the limit of viability and intact survival (28 wks) in MC twin. More researches are needed to answer this question.
