Management of monochorionic twins discordant for structural fetal anomalies.

Objective: To review the perinatal management and outcomes of monochorionic twin pregnancies (MC) discordant for congenital anomalies (DCA).

Methods: Retrospective, study of all MC DCA cases referred to our tertiary referral center from 1997 to 2018. We excluded cases complicated with twin-to-twin transfusion syndrome, twin anemia-polycythemia sequence, twin reversed arterial perfusion sequence or selective intra-uterine growth restriction.

Meconium peritonitis in both fetuses with early twin-to-twin transfusion syndrome.

Twin-to-twin transfusion syndrome (TTTS) is due to unbalanced inter-twin bloodflow through placental vascular anastomoses. We present a TTTS case treated with fetoscopic laser photocoagulation (FLP) that was complicated by perinatal meconium peritonitis in both twins. Ten weeks following laser treatment, the two fetuses showed intra-abdominal hyperechogenicity and ascites.

Long-term developmental follow-up of infants who participated in a randomized clinical trial of amniocentesis vs laser photocoagulation for the treatment of twin-to-twin transfusion syndrome.

Objective: We sought to assess long-term neurodevelopment of children who were treated prenatally as part of the Eurofoetus randomized controlled trial.

Study Design: The study population was composed of 128 cases of twin-to-twin transfusion syndrome (TTTS) included and followed up in France. Survivors were evaluated by standardized neurological examination and by Ages and Stages Questionnaires (ASQ).

Pseudoamniotic band syndrome: a rare complication of monochorionic twins with fetofetal transfusion syndrome treated by laser coagulation.

Objective: The purpose of this study was to assess the incidence and risk factors of limb constriction defects that are related to pseudoamniotic band syndrome (PABS) after selective fetoscopic laser surgery (FLS) in fetofetal transfusion syndrome (FFTS).

Study Design: All consecutive cases of FFTS that were treated by selective FLS between 1999 and 2006 were examined prospectively for PABS at the time of delivery. Incidence and characteristics of PABS were reported.
