Marium Naveed Khan, William F Walsh
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...

BACKGROUND: Twins, compared to singletons, have higher perinatal mortality and morbidity. The aim of this study was to describe the twinning rate, epidemiological variables and hospital outcome of twin deliveries and to find out ways of better management of twins in our part. METHODS: A retrospective evaluation of the outcome of 92 twin pregnancies during one year study period (1st January 2014 to 31st December 2014) was conducted at BPKIHS. Twins delivered within the institution were included but cases less than 28 weeks gestation were excluded...

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 (TTTS) or selective intrauterine growth restriction (sIUGR)...

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...

INTRODUCTION: Monochorionic-diamniotic (MCDA) twin pregnancies are high risk, due to twin-to-twin transfusion syndrome (TTTS), twin anaemia polycythaemia sequence (TAPS) and intrauterine growth restriction (IUGR). There is limited evidence to guide ultrasound surveillance protocols. Using a retrospective cohort, we aimed to provide insight into the optimal interval of ultrasound surveillance. METHODS: Retrospective cohort of women with MCDA pregnancies who received antenatal care at Monash Medical Centre (January 2011-October 2014)...

BACKGROUND: Twin-to-twin transfusion syndrome (TTTS) affects 10-20 % of monochorionic diamniotic (MCDA) births and accounts for 50 % of fetal loss in MCDA pregnancies. This exploratory qualitative study identified shared experiences, including potential emotional and psychosocial impacts, of this serious disease. METHODS: Forty-five publicly accessible, online stories posted by families who experienced TTTS were analyzed using grounded theory. RESULTS: Shared TTTS experiences included a common trajectory: early pregnancy experiences, diagnostic experiences, making decisions, interventions and variable outcomes...

OBJECTIVE: Severe right Ventricular Outflow Tract Obstruction (RVOTO) is a complication in recipient twins in Twin-to-Twin-Transfusion Syndrome (TTTS), which requires post-partum follow-up or treatment. The objective of our study was to evaluate pregnancy characteristics of neonates with RVOTO in complicated monochorionic twin pregnancies. In the TTTS cases we aimed to determine the incidence and to construct a prediction model for the development of RVOTO. METHODS: An observational cohort study of all complicated monochorionic twin pregnancies with a post-partum neonatal diagnosis of RVOTO was performed...

OBJECTIVE: The aim of this systematic review and meta-analysis was to assess the role of first trimester and early second trimester markers for the prediction of twin-to-twin transfusion syndrome (TTTS) in monochorionic twin pregnancies. METHODS: MEDLINE, EMBASE and ClinicalTrial.gov were searched from inception to April 2014. The MeSH term "fetofetal transfusion" was searched in combination with the phrases "predictive value", "sensitivity", "specificity", "false positive", "false negative", "screening", "accuracy" and "ROC"...

Perinatal mortality is increased considerably in multiple pregnancies compared to singleton pregnancies, with single intrauterine fetal demise (sIUFD) presenting a rare but unique perinatal problem. Monochorionic pregnancies are at particular risk of sIUFD due to bidirectional inter-twin placental vascular anastomoses. The resulting inter-twin blood flow can become unbalanced, causing acute and chronic inter-twin transfusion and profound anemia secondary to fetal exsanguination into the low-pressure circulation of the dead fetus...

Monochorionic twin pregnancies can be complicated by twin-to-twin transfusion syndrome (TTTS). The best treatment option for TTTS is fetoscopic laser coagulation of the vascular anastomoses between donor and recipient. After laser therapy, up to 33% residual anastomoses were seen. These residual anastomoses can cause twin anemia polycythemia sequence (TAPS) and recurrent TTTS. In order to reduce the number of residual anastomoses and their complications, a new technique, the Solomon technique, where the whole vascular equator will be coagulated, was introduced...

OBJECTIVE: Laser ablation of all placental vascular anastomoses is the optimal treatment for twin-twin transfusion syndrome (TTTS). However, two important controversies are apparent in the literature: (a) a gap between concept and performance, and (b) controversy regarding whether all the anastomoses can be identified endoscopically and whether blind lasering of healthy placenta is justified. The purpose of this article is: (a) to address the potential source of the gap between concept and performance by analyzing the fundamental steps needed to successfully accomplish the surgery, and (b) to discuss the resulting competency benchmarks reported with the different surgical techniques...

OBJECTIVE: The purpose of this article is to review the definition of twin-to-twin transfusion syndrome (TTTS) and the sonographic diagnostic assessment of these cases prior to therapy. MATERIALS AND METHODS: The article addresses the terminology used to refer to the condition and describes the systematic ultrasound assessment of the condition, including the ultrasound diagnosis, the staging of the disease, cervical assessment and pre-operative mapping. RESULTS: From an etymologic and medical point of view, the term 'fetofetal transfusion' is more appropriate than 'TTTS'...
