Article Abstract
Objectives: To report a cohort of dichorionic triamniotic (DCTA) triplets with access to contemporary fetal interventions.
Design: Prospective study.
Setting: A regional referral center for the diagnosis and management of complicated multiple pregnancies.
Population: All DCTA triplets receiving consultation and prenatal care at our center from 2010 to 2015.
Methods: The following management alternatives for DCTA were offered: 1) expectant management; 2) reduction of one or two fetus of the monochorionic (MC) component using radiofrequency ablation (RFA) after 16 weeks or potassium chloride (KCL) before 16 weeks, respectively; 3) reduction of the isolated fetus using KCL before 16 weeks.
Main Outcome Measure: Survival rate of different management alternatives.
Results: A total of 47 DCTA triplets were included in this study. After consultations on possible prognosis and management options, 19 patients chose expectant management, 14 patients opted RFA to reduce one fetus of the MC component, 14 patients required KCL to reduce the MC component. Fetal demise per pregnancy occurred more frequently in the subgroup managed expectantly (53%) compared to subgroups managed with RFA (7%, p = .02) or KCL (0%, p = .02). Overall survival was significantly lower in DCTA triplets managed expectantly (58%) compared to subgroup managed with RFA (93%, p < .01) or KCL (100%, p = .04).
Conclusion: Fetal reduction seems to improve perinatal survival in DCTA triplets.

Article Synopsis
- The rise in multiple pregnancies is linked to assisted reproductive technology, with a focus on minimizing risks associated with dichorionic triamniotic (DCTA) triplet pregnancies.
- The article presents two cases where multifetal pregnancy reduction (MFPR) was performed to convert high-risk DCTA triplets to safer dichorionic diamniotic (DCDA) twins, allowing for a healthier pregnancy outcome.
- The study suggests that for couples facing multiple pregnancies, reducing DCTA triplets to DCDA twins could be a feasible option, contingent on the clinical assessment of the situation.

Background: It is generally beneficial and recommended that dichorionic triamniotic (DCTA) triplet pregnancies be reduced to monochorionic (MC) twin or singleton pregnancies after assisted reproductive technology (ART). However, some infertile couples still have a firm desire to retain twins. For this reason, the best foetal reduction strategies need to be available for infertile couples and clinicians.

Objective: To compare the outcomes of dichorionic triamniotic (DCTA) triplets who underwent fetal reduction (FR) to singletons or twins with those managed expectantly.
Methods: We conducted a retrospective study of DCTA triplets with three living fetuses at 11-14 weeks over a 7-year period. Pregnancy outcomes were compared following different management strategies.

Background: Dichorionic triamniotic (DCTA) triplet pregnancies are rare in spontaneous pregnancy. The aim was to characterize the incidence and risk factors of DCTA triplet pregnancies after assisted reproductive technology (ART).
Methods: A retrospective analysis of 10,289 patients, including 3,429 fresh embryo transfer (ET) cycle and 6,860 frozen ET cycle, was performed from January 2015 to June 2020.

Objective: To compare the outcomes of dichorionic triamniotic (DCTA) triplets with that of monochorionic diamniotic (MCDA) twin gestations undergoing fetoscopic laser surgery (FLS) for treatment of twin-to-twin transfusion syndrome (TTTS).
Methods: Retrospective cohort study of prospectively collected data of consecutive DCTA triplet and MCDA twin pregnancies with TTTS that underwent FLS at two fetal treatment centers between 2012 and 2020. Preoperative, operative and, postoperative variables were collected.
