Monochorionic monoamniotic pregnancy are considered high risk gestations and the fetal outcome is at times unpredictable. Correct diagnosis and counselling are extremely important, especially regarding the risk of unexpected fetal demise. We present the rare case of a monochorionic monoamniotic twin pregnancy with early identification of cord entanglement and the characteristic ultrasound findings in the first trimester of pregnancy.

Introduction: Fetoscopic laser surgery (FLS) is the gold standard treatment for monochorionic (MC) twin pregnancies complicated by twin-twin transfusion syndrome (TTTS). The aim of our study was to evaluate the rate and risk factors for cord entanglement in the presence of iatrogenic monoamnioticity (iMA), a consequence of inadvertent septostomy during FLS.
Methods: This is a retrospective analysis of two consecutive cohorts of FLS performed either using the selective technique from January 2004 to January 2012, or with the Solomon technique, from that date onwards.

Objective: The objective of this study was to conduct a longitudinal assessment of inter-twin growth and Doppler discordance, to identify possible distinct patterns, and to investigate the predictive value of longitudinal discordance patterns for adverse perinatal outcomes in twin pregnancies.
Methods: This retrospective cohort study included twin pregnancies followed and delivered at a tertiary University Hospital in London (UK), between 2010 and 2023. We included pregnancies with at least three ultrasound assessments after 18 weeks and delivery after 34 weeks' gestation.

Twin pregnancy is considered high-risk pregnancy because of its various effects on maternal and fetal physiology. Twin pregnancy can be dizygotic or monozygotic, the latter being less common. Depending upon the period of separation of an embryo, monozygotic twins can share amniotic cavity and placenta with the monochorionic monoamniotic form being the least common type.
