Objective: This guideline reviews the evidence-based management of normal and complicated monochorionic twin pregnancies.
Target Population: Women with monochorionic twin or higher order multiple pregnancies.
Benefits, Harms, And Costs: Implementation of these recommendations should improve the management of both complicated and uncomplicated monochorionic (and higher order multiple) twin pregnancies. They will help users monitor monochorionic twin pregnancies appropriately and identify and manage monochorionic twin complications optimally in a timely manner, thereby reducing perinatal morbidity and mortality. These recommendations entail more frequent ultrasound monitoring of monochorionic twins compared to dichorionic twins.
Evidence: Published literature was retrieved through searches of PubMed and the Cochrane Library using appropriate MeSH headings (Twins, Monozygotic; Ultrasonography, Prenatal; Placenta; Fetofetal Transfusion; Fetal Death; Fetal Growth Retardation). Results were restricted to systematic reviews, randomized controlled clinical trials, and observational studies. There were no date limits, but results were limited to English or French language materials.
Validation Methods: The content and recommendations were drafted and agreed upon by the principal authors. The Board of the SOGC approved the final draft for publication. The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See online Appendix A (Tables A1 for definitions and A2 for interpretations of strong and conditional [weak] recommendations).
Intended Audience: Maternal-fetal medicine specialists, obstetricians, radiologists, sonographers, family physicians, nurses, midwives, residents, and other health care providers who care for women with monochorionic twin or higher order multiple pregnancies.
Tweetable Abstract: Canadian (SOGC) guidelines for the diagnosis, ultrasound surveillance and management of monochorionic twin pregnancy complications, including TTTS, TAPS, sFGR (sIUGR), acardiac (TRAP), monoamniotic twins and intrauterine death of one MC twin.
Summary Statements: RECOMMENDATIONS.

Monochorionic twin pregnancies are a subset of twin pregnancies that face potential complications related to a shared circulation between the fetuses. These complications are related to anastomotic placental vessels connecting the cardiovascular systems of the two fetuses, which can result in significant sequela if one twin experiences intrauterine death. The sudden cardiovascular collapse in this scenario leads to a massive blood shift away from the healthy co-twin, significantly jeopardizing its life and long-term neurodevelopmental outcome.

Background: To date, there have been no studies in Poland on weight gain in women with twin pregnancies in relation to recommendations.
Objective: The aim of this study was to analyze the gestational weight gain of women with twin pregnancies depending on their body weight before pregnancy, and to assess the relationship between the observed weight gain and the neonatal birth weight.
Material And Methods: The study was conducted among 50 women in twin pregnancies and their 100 newborns delivered after 36 weeks of gestation.

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.

A tribute to the life and career of Dr Milton Diamond, a leading figure in twin studies of transsexuality and gender identity, is presented. Dr Diamond is famous for revealing the truth about the unsuccessful effort to change a monozygotic male Canadian twin into a female, following accidental ablation of his penis during circumcision. A short summary of recent twin research on human sexuality and transsexuality, focused on Dr Diamond's contributions, is then presented.

Twin pregnancies account for 3% of all pregnancies and they are burdened by higher morbidity and mortality compared to singletons. The role of ultrasound in the screening, diagnosis and management of possible complications of twin pregnancies has been widely investigated in the current literature. However, despite the progress that have been made in the last decades regarding treatment and evidence-based management of complications, twin pregnancies remain at higher risk of adverse outcomes, requiring therefore dedicated surveillance.
