AI Article Synopsis
- The study aims to compare maternal and neonatal outcomes in dichorionic diamniotic (DCDA) twin pregnancies conceived through assisted reproductive technology (ART) versus those conceived spontaneously (SC).
- Analysis of 18 cohort studies involving over 10,000 women revealed that ART pregnancies had higher risks of complications such as preeclampsia, gestational diabetes, and higher rates of cesarean sections compared to SC pregnancies.
- Despite these increased risks, the absolute rates of complications were relatively low, suggesting that the benefits of ART in achieving twin pregnancies may outweigh these potential risks.
Article Abstract
Purpose: Assisted reproductive technology (ART) is commonly used to achieve pregnancy and often results in dichorionic diamniotic (DCDA) twin pregnancies. However, the potential risks of ART on maternal and neonatal outcomes in these pregnancies are not well understood. The objective is to compare the maternal and neonatal outcomes in DCDA twin pregnancies between those achieved through ART and those spontaneously conceived (SC).
Methods: We carried out a systematic comprehensive search of electronic databases; namely, PubMed, Embase, Scopus, and the Cochrane Library, from inception to March 2023 with a study period of recruitment between 2003 and 2023. We included all studies comparing the maternal and neonatal outcomes of DCDA twin pregnancies between those achieved by ART and those SC.
Results: We analyzed data from 18 cohort studies involving 10,485 women with DCDA twin pregnancies. The meta-analysis showed that ART-conceived pregnancies had a significantly higher risk of preeclampsia or gestational hypertension (GH), gestational diabetes mellitus (GDM), placenta previa (PP), placental abruption (PA), postpartum hemorrhage (PPH), and elective and emergency cesarean sections than SC twin pregnancies. The absolute risks of these complications remained relatively low. We also found a slightly higher risk of respiratory distress syndrome (RDS) and congenital malformations in ART-conceived infants compared to the risks in SC infants. Finally, the risk of neonatal intensive care unit (NICU) admissions was significantly higher in ART-conceived infants than in SC infants, but with high heterogeneity.
Conclusion: We found associations between DCDA twin pregnancies conceived through ART and increased frequencies of adverse maternal outcomes. However, the absolute risks of these complications remained low, and the benefits of ART for achieving successful pregnancies may well outweigh the potential risks. Additionally, ART-conceived DCDA twin pregnancies may pose higher risks of RDS, congenital malformations and NICU, admissions than SC DCDA twin pregnancies.

Objectives: To clarify the prenatal magnetic resonance (MR) imaging characteristics of fetal intracranial haemorrhages (ICHs) in a large cohort and correlate them with birth outcomes.
Methods: We retrospectively reviewed MR images of fetuses with ICH on screening ultrasound (US) on picture archiving communication system (PACS) servers within a nearly ten-year period from two medical tertiary centres. The indications, main abnormal findings and coexistent anomalies were recorded by two experienced radiologists with census readings.

Introduction Multifetal pregnancies, which account for 2-4% of births worldwide, have increased in recent years. Twin pregnancies carry a higher risk of preterm birth and associated neonatal morbimortality, with monochorionic twins considered at greater risk. This study investigates the influence of chorionicity on neurodevelopmental outcomes in preterm twins.

Objective: To determine if the resolution of fetal growth discordance after laser surgery in pregnancies with twin-to-twin transfusion syndrome (TTTS) and coexisting selective fetal growth restriction (sFGR) can be predicted by estimated fetal weight (EFW) discordance recorded prior to the development of TTTS (pre-TTTS).
Methods: This was a single-center, retrospective analysis of prospectively collected data on monochorionic twins with concurrent TTTS and sFGR that underwent laser surgery and had available growth ultrasound records from a pre-TTTS ultrasound evaluation. Maternal demographics, pregnancy characteristics and birth outcomes were compared between three outcome groups: double twin survival with resolved sFGR determined by birth weight discordance (BWD) < 20%; double twin survival with ongoing sFGR determined by BWD ≥ 20%; and single or double fetal demise after laser surgery.

Red blood cell (RBC) alloimmunization can occur because of exposure to various sensitizing factors and poses a constant threat in transfusion. Assisted reproductive technology (ART) involves manipulation of sperm, ova, or embryos with the goal of producing a pregnancy. We present an interesting case of ART-induced maternal alloimmunization (AIMA) due to anti-c in a woman carrying a twin pregnancy.
