INTRODUCTION: This study aimed to investigate the risk factors, incidence, and influence on the perinatal outcome of chorioamniotic membrane separation (CMS) after fetoscopic laser photocoagulation (FLP). MATERIAL AND METHODS: This retrospective study included 312 women who underwent FLP for twin-to-twin transfusion syndrome (TTTS). Clinical records were used to review obstetrical examinations, complications, operative data, ultrasonographic findings, and perinatal and neonatal follow-up data in all patients...

Dizygotic monochorionic twin pregnancies can result in blood chimerism due to in utero twin-to-twin exchange of stem cells. In this case, we examined the proportion of allogeneic red blood cells (RBCs) by flow cytometry and the proportion of allogeneic nucleated cells by digital PCR at seven months and again at five years. We found an increase in the proportion of allogeneic cells from 63% to 89% in one twin, and a similar increase in autologous cells in the other twin from 57% to 84%. A paradigm for stem cell therapy could be modelled on this case: induction of tolerance and chimerism by antenatal transfusion of donor stem cells...

Solid organ transplantation in pediatric patients has been a reality since 1954, when the first kidney transplantation was successfully performed between identical twins. We report the long-term outcomes, with more than 25 years of follow-up, in a patient born with hypoplastic left heart syndrome (HLHS) who received a heart transplant from a dizygotic twin. While we would not wish for this situation to reoccur, we hope that in reporting it, we can add to the discussion surrounding pediatric heart transplantation and the management of HLHS...

We have developed a calibration target for use with fluid-immersed endoscopes within the context of the GIFT-Surg (Guided Instrumentation for Fetal Therapy and Surgery) project. One of the aims of this project is to engineer novel, real-time image processing methods for intra-operative use in the treatment of congenital birth defects, such as spina bifida and the twin-to-twin transfusion syndrome. The developed target allows for the sterility-preserving optical distortion calibration of endoscopes within a few minutes...

Twin-to-twin transfusion syndrome (TTTS) at times complicates monochorionic twin gestations, resulting in conditions ranging from discordant sizes to fetal demise of one baby. Various types of cardiac defects have been described in the recipient twin of this syndrome. Isolated great artery calcification, i.e. aortic and pulmonary artery calcification is one such uncommon condition associated with TTTS. Calcification of the walls of great vessels may be due to chronic vascular injury sustained as a result of circulatory volume overload in the recipient twin...

Twin-to-twin transfusion syndrome (TTTS) complicates 10% of monochorionic twin pregnancies and it is consequence of an unbalanced exchange blood through the vascular anastomoses at placental surface. If not treated, mortality rates in TTTS may be as high as 80-100%. Laser photocoagulation of the placental anastomoses is the first treatment option; however, in some situations, the damage of the placenta in the postpartum may become difficult the residual anastomoses identification. We propose a new non-invasive technique to assess the residual anastomoses using computed tomography (CT) scan data to generate a three-dimensional (3D) virtual placentoscopy...

The early diagnosis of the Twin-To-Twin transfusion syndrome (TTTS) carries benefits of the better survivor for the fetus-donor; but at the same time there are obvious practical impediments to diagnose the condition earlier in the course of a pregnancy. That's why this particular problem in practical medicine requires in depth investigation to clarify casual factors, and specify tactical approach to the prospective patients which in turn will lead to prevention of the fetal death and damage and improvement of fetal survivor in any form of TTTS...

INTRODUCTION AND OBJECTIVES: Many international studies have demonstrated that delayed umbilical cord clamping reduces neonatal morbidity. However, in France, delayed umbilical cord clamping is still not performed in many neonatal units. The aims of this study were to evaluate the feasibility of developing a protocol of delayed umbilical cord clamping in the maternity ward of the Toulouse university hospital and to evaluate the impact of this new protocol on neonatal mortality. METHODS: We conducted a prospective observational study including 123 preterm infants born before 37 weeks of gestation between June 2012 and June 2013 and hospitalized at birth...

BACKGROUND AND AIMS: Twin pregnancy with monochorionic placenta may be associated with arteriovenous vascular anastomosis of the placental vessels resulting in twin-to-twin transfusion syndrome (TTTS) and twin reversed arterial perfusion syndrome (TRAP). Foetoscopic LASER ablation (FLA) is the treatment of choice in reducing foetal mortality related to this. METHODS: A retrospective review of medical records of 41 FLA procedures for TTTS and TRAP were analysed for anaesthetic management...

A monochorionic-diamniotic twin baby presented with intrauterine growth restriction and anuria. The baby was found to have bladder agenesis, a pelvic dysplastic horseshoe kidney, vertebral anomalies, a ventricular septal defect and facial dysmorphisms. It was surprising to find no abnormalities in amniotic fluid indices prenatally, suggesting the possibility of urine output that declined as the pregnancy proceeded. Some degree of twin-to-twin transfusion of amniotic fluid was also possible, which could have rescued the oligohydramnios known to be associated with kidney and urinary tract abnormalities...

The aim of this study was to determine the effects of intrauterine environment on the magnitude of intrapair differences in six somatic traits of monozygotic (MZ) and dizygotic (DZ) twins (1,263 pairs; 424 MZ twins and 839 DZ twins). Differences in intrauterine environments of MZ twins enforced division of the research material into four groups: (1) MZ-MC-TTTS - MZ twins from monochorionic (MC) pregnancies with twin-to-twin transfusion syndrome (TTTS), (2) MZ-MC (without TTTS)-MZ twins from MC pregnancies without TTTS, (3) MZ-DC-MZ twins from dichorionic (DC) pregnancies, and (4) DZ-DZ twins...

Pulmonary artery, and rarely aortic, calcifications have been reported in sporadic case reports in the recipient twin of twin-to-twin transfusion syndrome. This presentation is more likely to be secondary to the haemodynamic alterations in the recipient twin, but must be differentiated from idiopathic infantile arterial calcification as the clinical implications, treatment, and prognosis may be drastically different.

BACKGROUND: Monochorionic diamniotic (MCDA) twin pregnancies are associated with adverse perinatal outcome. Intertwin discordances at the time of nuchal translucency (NT) screening may have a value in the prediction of fetal loss or twin-to-twin transfusion syndrome. We aimed to determine the ability of intertwin NT and crown rump length (CRL) discordances among MCDA twins to predict adverse outcomes. MATERIAL AND METHODS: All MCDA twins with a documented routine ultrasound at 11 to 13+6 weeks' gestation, and known pregnancy outcome between August 2003 and August 2012 were included...

OBJECTIVE: To estimate the risk for twin anemia-polycythemia sequence (TAPS) and adverse perinatal outcome in monochorionic diamniotic (MCDA) twin pregnancies with amniotic fluid discordance (AFD). METHODS: Retrospective cohort study of 34 MCDA pregnancies with AFD (intertwin difference of ≥3 cm in maximal vertical pocket measurement) without meeting the criteria for twin to twin transfusion syndrome or selective intrauterine growth restriction. Perinatal outcome measures and the risk for TAPS were compared with a control group consisted of 101 MCDA twin pregnancies without AFD, twin to twin transfusion syndrome, or selective intrauterine growth restriction...

Monochorionic multiple pregnancy has a higher risk for obstetric complications, including those due to the development of twin-to-twin transfusion syndrome and reversed arterial perfusion syndrome (TRAP sequence). The latter occurs in 0.1% of all monochorionic pregnancies. The basis for TRAP sequence is a relationship between arterial and venous anastomoses from the appropriate placental areas, causing a recipient fetus to develop at the expense of a donor fetus. The presence of abnormal anastomoses is considered to be a main cause of acardia...
