Perinatal outcome of dichorionic-triamniotic as compared to trichorionic triplets

Abstract

AbstractObjective:To evaluate if the perinatal outcomes of dichorionic-triamniotic (DC) triplets are significantly different than that of trichorionic (TC) triplets.Study design:Comparison of maternal and neonatal data of 44 DC to 46 TC triplets, using univariate analysis.Results:DC triplets were significantly more common after spontaneous conception but all other maternal characteristics as well complications and cesarean section rates were similar. Both groups had similar incidence of birth at <32 and <28 weeks as well as similar incidence of very low and extremely low birth weight. There was similar incidence of neonatal morbidity except for twin-twin transfusion syndrome (13.6%) in the DC group. The stillbirth rate was 45/1000 and 29/1000, the early neonatal mortality rates were 63/1000 and 45/1000, and the perinatal mortality rate was 106/1000 and 72/1000 for DC and TC triplets, respectively (all not significantly different).Conclusions:Our data indicate that DC twins are not significantly disadvantaged compared to TC triplets and the similar outcomes might be reassuring for those who consider continuing their DC triplet pregnancy.
