“…The incidence of perinatal death varied in several previous studies regarding the effect of chorionicity on perinatal outcomes in triplet gestations with MC placentation [4,14,15,16]. Two large retrospective cohort studies reported incidences of perinatal death of 15.7 and 26.4% [14,15], which are higher than in the current study.…”

“…The rates of perinatal mortality and morbidity have reportedly decreased with time as a result of multidisciplinary work to improve perinatal and neonatal care [17,18,19]. The lower incidence of perinatal death (3.7%) in a later large study published in 2013 [4] might also support this assumption, although the study was limited by the exclusion of triplet pregnancies that were at <22 weeks of gestation. Second, the introduction of FLP for FFTS in triplet gestations might also help to explain the differences in the results.…”

“…The incidences of miscarriage and preterm birth at <28 weeks of gestation in triplet gestations are 3-9 and 7%, respectively, and 37% of triplets meet the criteria for extremely low birth weight [4,5]. …”

“…In addition to these risks that are primarily related to premature birth, chorionicity plays a role in the perinatal prognosis of triplet gestations, similar to that in monochorionic (MC) twin gestations [1,2,4]. Triplet gestations with MC placentation, which include MC triamniotic (MCTA) and dichorionic triamniotic (DCTA) triplet gestations, are at risk of feto-fetal transfusion syndrome (FFTS), which is caused by a blood imbalance via placental vascular anastomoses.…”

Introduction: This study aimed to determine the incidences of feto-fetal transfusion syndrome (FFTS) and perinatal outcomes in triplet gestations with monochorionic placentation. Materials and Methods: In this retrospective cohort study, we evaluated the incidences of FFTS and perinatal outcomes at 28 days of age in cases of triplet gestations with monochorionic placentation who visited our centers before 16 weeks of gestation and delivered over a period of 11 years. Results: In 41 triplet gestations (17 monochorionic triamniotic, 22 dichorionic triamniotic, 1 dichorionic diamniotic, and 1 monochorionic monoamniotic), the incidence of FFTS was 17.1%, and the median gestational age at FFTS diagnosis was 19 weeks. In 123 triplets, the incidences of fetal death and neonatal death at 28 days of age were 8.1 and 0.9%, respectively. None of the surviving infants had grade 3 or 4 intraventricular hemorrhage, while cystic periventricular leukomalacia occurred in 6 of 113 infants (5.3%). The incidence of poor outcomes (death or any major neurological complication at 28 days of age) was 13.8%. Discussion: Seventeen percent of triplet pregnancies with monochorionic placentation developed FFTS, and 14% had a poor outcome. Therefore, triplet gestations with monochorionic placentation should be followed carefully.

“…These outcomes are influenced by many perinatal factors. For example, antenatal factors include obstetrician's attitude [1], gestational age [2], sex [3], antenatal corticosteroid therapy [3], multi fetal pregnancy [4], growth restriction and so on [5,6], and neonatal factors include circulatory and respiratory instability [7], intracranial hemorrhage, Periventricular leukomalacia [8], intestinal perforation [9], and so on.…”
