Maternal, perinatal and neonatal outcomes of triplet pregnancies according to chorionicity: our 13-year experience at Careggi University Hospital in Florence, Italy

Objective. Triplet pregnancies are associated with a higher risk of foetal and maternal morbidity and mortality compared to twins and singletons. Chorionicity has been proposed as a major determinant of perinatal and maternal outcomes in triplet pregnancies, although further evidence is needed to clarify the extent and real influence of this factor. Thus, this study aimed to evaluate the effect of chorionicity on adverse maternal, foetal, and neonatal outcomes in triplet pregnancies.
