Monochorionic triamniotic (MCTA) pregnancies present a high number of complications, mainly due to the presence of unbalanced vascular anastomoses, such as twin anemia-polycythemia sequence (TAPS). Previous reported cases related to TAPS are in twin pregnancies or only affect the monochorionic component of dichorionic triamniotic (DCTA) pregnancies. We report an exceptional case, the only one reported as far as we know, of a MCTA pregnancy that developed a TAPS in which the three triplets are implicated, from two donors to one recipient. The pregnancy had been previously sonographically diagnosed as DCTA pregnancy and this could not explain the clinical results. The pathological study of the placenta showed the presence of three monochorionic dividing membranes, a congested area in the recipient parenchyma and two non-congested areas in the donor's parenchyma that confirmed the clinical findings. Pathological study of multiple placentas should always be done because it provides understanding of pregnancy complications.

Objectives: To investigate the perinatal outcomes of SR using radiofrequency ablation (RFA) in MC pregnancies, identified factors affecting these outcomes, and assessed the associated learning curve.
Methods: This retrospective cohort study included all consecutive MC pregnancies that required RFA from September 2013 to April 2023 at our institution. The perinatal outcomes were compared on the basis of various indications, and binary logistic regression analysis was performed to identify the risk factors for cotwin loss.

Twin pregnancies are at increased risk of morbidity and mortality compared to singletons. Among all twins, monochorionic pregnancies are at higher risk of specific and non-specific complications compared to dichorionic pregnancies. Therefore, it is of great importance to properly counsel future parents with monochorionic pregnancies regarding the risks of adverse outcomes and the modalities of monitoring and intervention of the potential complications.

Complications of twin pregnancy such as twin anemia-polycythemia sequence (TAPS), which involve placental anastomotic vessels, occur mostly in monochorionic diamniotic twins and they have rarely been reported in dichorionic diamniotic (DD) twins. Here, we report a case of DD twins diagnosed with TAPS with fetal hydrops caused by fetal anemia at 28 weeks, which resolved spontaneously during pregnancy. A 37-year-old pregnant woman was referred to our hospital because of a twin pregnancy at 13 weeks.
