“…In addition to twin-twin transfusion syndrome (TTTS), monochorionicity imparts greater risk of perinatal mortality, stillbirth, intrauterine death after 32 weeks, neonatal intensive care unit (NICU) admission, and preterm delivery compared to DC twins. [1][2][3][4][5][6][7][8][9][10][11] As a result, women carrying twin pregnancies receive extensive antenatal counseling on fetal risks, but less is known about whether the presence of one versus two placentas confers dissimilar maternal risks.…”

“…Hence, the modelbased percentiles can be interpreted as relating to a hypothetical population of pregnancies in which there are no deliveries prior to full term. This assumption is of course problematic, particularly given the high rate of preterm delivery in twin pregnancies, with one large study reporting delivery before 37 weeks in 41% of DCDA and 56% of MCDA cases [8] . The naïve quantile regression approach does not make such an assumption.…”

Introduction: This study investigates patterns of intertwin size discordance in dichorionic diamniotic (DCDA) and monochorionic diamniotic (MCDA) twin pregnancies. Material and Methods: Ultrasound measurements of twin pregnancies, from 14 weeks to term, were collected by 9 hospitals over a 10-year period. This analysis considers the modelled and observed levels of discordance in abdominal circumference (AC) and estimated fetal weight (EFW) in relation to gestational age. Fitted models were analysed to produce charts displaying the expected range of intertwin discordance in AC and EFW at any given examination. Results: The dataset for analysis included a total of 9,866 ultrasound examinations in 1,802 DCDA and 323 MCDA twin pregnancies. The 95th percentile of intertwin discordance in EFW increased from 18.3% (95% CI, 17.8-18.7%) at 20 weeks to 21.9% (95% CI, 21.3-22.4%) at 30 weeks for DCDA pregnancies. The 95th percentile for intertwin discordance in AC was stable at 10-11% for this period. Slightly higher levels of discordance were observed for MCDA than for DCDA pregnancies. Discussion: The expected range of intertwin discordance in EFW and AC shows differences with gestational age and between DCDA and MCDA pregnancies.

“…MC pregnancies account for a significant proportion of perinatal morbidity and mortality in twins [3,4,5]. The perinatal mortality rate is around twice and 4 times as high as in dichorionic twins and single pregnancies, respectively [6].…”

A Systematic Approach to the Differential Diagnosis and Management of the Complications of Monochorionic Twin Pregnancies

Monochorionic (MC) twins represent a significant proportion of perinatal morbidity and mortality. Overall, 1 of 3 MC twin pregnancies will develop complications in relation to the MC placenta and the presence of interfetal placental anastomoses. From a clinical standpoint, these complications can be grouped into four main types of clinical problems: chronic transfusion, acute transfusion, growth discordance, and discordant malformation. Differential diagnosis of MC twin complications is still challenging due to frequent overlap of their clinical signs and the complex relationships between them. Clinical experience demonstrates that most instances of wrong management derive from failure to comply with a basic set of rules for diagnosis and management. In this review, we propose a simplified approach to the understanding of MC twin pregnancy, its potential complications, and the key concepts allowing adequate differential diagnosis and targeted management.
