Perinatal outcome of dichorionic-triamniotic as compared to trichorionic triplets

Area of Science:

• Perinatology
• Maternal-Fetal Medicine
• Reproductive Medicine

Background:

• Triplet pregnancies present unique challenges in perinatal care.
• Dichorionic-triamniotic (DC) and trichorionic (TC) are distinct placental arrangements in triplet gestations.
• Understanding comparative perinatal outcomes is crucial for clinical management.

Purpose of the Study:

• To compare the perinatal outcomes between dichorionic-triamniotic (DC) and trichorionic (TC) triplet pregnancies.
• To identify any significant differences in maternal and neonatal complications.
• To provide data for counseling individuals considering continuing DC triplet pregnancies.

Main Methods:

• A comparative study involving 44 DC and 46 TC triplet pregnancies.
• Univariate analysis was employed to compare maternal and neonatal data.
• Key outcomes assessed included gestational age at birth, birth weight, neonatal morbidity, and mortality rates.

Main Results:

• DC triplets were more frequently conceived spontaneously.
• Maternal characteristics, complication rates, and cesarean section rates were similar between DC and TC groups.
• While twin-twin transfusion syndrome occurred in 13.6% of DC triplets, overall neonatal morbidity, stillbirth, and mortality rates did not significantly differ between the groups.

Conclusions:

• Dichorionic-triamniotic (DC) triplet pregnancies do not appear to be significantly disadvantaged compared to trichorionic (TC) triplets.
• The similar perinatal outcomes observed suggest that DC triplet pregnancies may be a viable option.
• These findings can reassure expectant parents and guide clinical decision-making regarding DC triplet gestations.
