Abstract
Monochorionic twins are at risk for complications due to the presence of placental vascular anastomoses, including twin-twin transfusion syndrome, twin anemia-polycythemia sequence, selective fetal growth restriction, and twin reversed arterial perfusion sequence. While ultrasound is the primary modality to screen for the development of these complications, MRI plays an important role in assessing monochorionic twin pregnancies for the development of other complications, such as neurologic injury. In this article, the authors review the ultrasound imaging findings associated with monochorionic twin complications, management options, and the role for MRI in these pregnancies.

Abstract
Targeted neonatal echocardiography (TNE) involves the use of comprehensive echocardiography to appraise cardiovascular physiology and neonatal hemodynamics to enhance diagnostic and therapeutic precision in the neonatal intensive care unit. Since the last publication of guidelines for TNE in 2011, the field has matured through the development of formalized neonatal hemodynamics fellowships, clinical programs, and the expansion of scientific knowledge to further enhance clinical care. The most common indications for TNE include adjudication of hemodynamic significance of a patent ductus arteriosus, evaluation of acute and chronic pulmonary hypertension, evaluation of right and left ventricular systolic and/or diastolic function, and screening for pericardial effusions and/or malpositioned central catheters. Neonatal cardiac point-of-care ultrasound (cPOCUS) is a limited cardiovascular evaluation which may include line tip evaluation, identification of pericardial effusion and differentiation of hypovolemia from severe impairment in myocardial contractility in the hemodynamically unstable neonate. This document is the product of an American Society of Echocardiography task force composed of representatives from neonatology-hemodynamics, pediatric cardiology, pediatric cardiac sonography, and neonatology-cPOCUS. This document provides (1) guidance on the purpose and rationale for both TNE and cPOCUS, (2) an overview of the components of a standard TNE and cPOCUS evaluation, (3) disease and/or clinical scenario-based indications for TNE, (4) training and competency-based evaluative requirements for both TNE and cPOCUS, and (5) components of quality assurance. The writing group would like to acknowledge the contributions of Dr. Regan Giesinger who sadly passed during the final revisions phase of these guidelines. Her contributions to the field of neonatal hemodynamics were immense.

Abstract
BACKGROUND To study the frequency of inherited thrombophilia in monochorionic twin pregnancies with twin-twin transfusion syndrome (TTTS). METHODS At the Department of Obstetrics of the Polytechnic University of Marche (Ancona, Italy) a population of monochorionic diamniotic pregnant women was selected retrospectively. After termination of the pregnancy, genotyping for Factor I, Factor V Leiden, Factor II and Methylenetetrahydrofolate Reductase (MTHFR), as well as activities of the plasma proteins C and S, was performed. RESULTS Regarding the 32 patients with TTTS, from a cohort of 104 monochorionic pregnancies recruited, at least one thrombophilic defect was more frequent (OR: 3.24), and the allele polymorphism frequency was higher for Factor I (OR: 4.4) and for Factor V Leiden (OR: 11.66). CONCLUSIONS Maternal inherited thrombophilia, possibly also inherited from monochorial fetuses, may result in impaired development of the placental vascular architecture. This inheritance hypothesis may explain why only a fraction of monochorionic diamniotic twins develop TTTS.

Abstract
Up to 20% of monochorionic diamniotic twin pregnancies can be complicated with twin-to-twin transfusion syndrome (TTTS). This complication is diagnosed by ultrasound demonstrating amniotic fluid discordance between both amniotic sacs, with polyhydramnios in the recipient's sac and oligohydramnios in the donor's, secondary to an imbalance in blood volume exchange between twins. Ultrasound evaluation of the amniotic fluid volume, bladder filling, and assessment of fetal Doppler parameters provide the basis for classification of TTTS, allowing severity assessment. The Quintero's staging system provides a standardized prenatal estimate on the risk of intrauterine fetal demise of one or both twins and the need for fetoscopic laser coagulation of placental vascular anastomoses or delivery depending on the gestational age. However, a proportion of TTTS cases may present without a linear progressive deterioration and no ultrasound signs of preceding staging, in rare situations, they arise even without amniotic fluid discordance. Thus, these unusual clinical presentations of TTTS have long been grouped into the category of atypical TTTS. In this review, we show the clues for diagnosis and management of different atypical cases of TTTS highlighting their underlying mechanism to improve the clinical understanding of such atypical situations, avoid misdiagnosis of TTTS, and allow a timely referral to a fetoscopic center.

Abstract
BACKGROUND Because of the progressive nature of twin-to-twin transfusion syndrome, difficulties in healthcare access during the COVID-19 pandemic may lead to delayed diagnosis and referral to fetal surgery centers, which may have repercussions on outcomes. OBJECTIVE This study aimed to assess the clinical impact of the COVID-19 pandemic on pregnancies complicated with twin-to-twin transfusion syndrome. STUDY DESIGN A retrospective cohort study of consecutive monochorionic diamniotic twin pregnancies complicated with twin-to-twin transfusion syndrome evaluated in our national referral fetal surgery center at Queretaro, Mexico, for possible surgical fetoscopy was conducted. Maternal-fetal characteristics and perinatal outcomes of cases evaluated during the first year of the World Health Organization's COVID-19 pandemic declaration (March 11, 2020 to March 10, 2021) were retrospectively compared with outcomes of cases evaluated during the same period in the previous year (March 11, 2019 to March 10, 2020). RESULTS Overall, 109 consecutive twin-to-twin transfusion syndrome cases were evaluated during the 2-year study period, 54 during the COVID-19 pandemic and 55 in the previous year. In the former group, a higher proportion of cases with fetal surveillance interval longer than 2 weeks (70.4% vs 47.3%; P=.01); twin-to-twin transfusion syndrome complications precluding laser therapy, such as intrauterine fetal demise, preterm rupture of membranes, or cervical dilatation with prolapsed amniotic membranes (18.5% vs 1.8%; P<.01); advanced twin-to-twin transfusion syndrome (53.7% vs 36.4%; P=.07); preoperative short cervix (25.9% vs 10.9%; P<.05); and lower overall perinatal survival (56.9% vs 80.0% [P=.01; at least 1 twin] and 39.2% vs 56.4% [P=.08; both twins], respectively) were observed. A significantly lower number of cases were selected for fetoscopic laser therapy during the pandemic (75.9% vs 92.7%; P=.01), with similar postoperative outcomes seen in both study periods. CONCLUSION In pregnancies with twin-to-twin transfusion syndrome, the COVID-19 pandemic has shown an adverse impact involving suboptimal fetal surveillance, advanced stages at diagnosis, poorer survival rates, and higher number of complications that preclude fetoscopic laser therapy.

Abstract
Objetivo: describir las características clínicas y la frecuencia de complicaciones maternas, fetales y neonatales, según técnica de anestesia neuroaxial (AN) en mujeres con síndrome de transfusión feto-fetal (STFF) tratadas con fotocoagulación láser (FL).
Materiales y métodos: estudio de cohorte retrospectiva descriptivo. Se incluyeron gestantes con STFF tratadas con FL y AN en la Fundación Valle del Lili, Cali (Colombia) entre 2013-2017. Se excluyeron pacientes con STFF estadio-V de Quintero. Se usó estadística descriptiva. El protocolo fue aprobado por el Comité de Ética de la institución.
Resultados: 32 participantes cumplieron con los criterios de inclusión y de exclusión. La población estuvo constituida por mujeres jóvenes, multíparas. En el 87,5% de los casos se realizó intervención de urgencia. El 43,7% presentaba el estadio-III de Quintero y en el 56,2 % de las gestantes se utilizó anestesia epidural. Las variables hemodinámicas maternas exhibieron un comportamiento similar, acorde al momento de la cirugía y la técnica neuoraxial implementada. El 65,6 % de las gestantes presentó hipotensión sostenida y el 9,3 % desarrolló edema pulmonar. El 65,6 % de las pacientes experimentó parto pretérmino y el 18,7 % ruptura prematura de membranas. Se registraron 14 muertes fetales y cinco neonatales. No se registraron casos de mortalidad materna.
Conclusiones: en pacientes con STFF que requieren FL, el uso de la anestesia epidural, espinal o combinada probablemente se asocia con un comportamiento similar al de las variables hemodinámicas maternas, durante los momentos de la cirugía. Los profesionales que brindan atención a estas gestantes deben estar alerta ante la frecuente aparición de complicaciones maternas, fetales y neonatales. Se requieren estudios prospectivos que evalúen la seguridad y la efectividad de las diferentes técnicas de anestesia neuroaxial en pacientes con STFF.

Abstract
Evidence for umbilical cord blood (UCB) cell therapies as a potential intervention for neurological diseases is emerging. To date, most existing trials worked with allogenic cells, as the collection of autologous UCB from high-risk patients is challenging. In obstetric emergencies the collection cannot be planned. In preterm infants, late cord clamping and anatomic conditions may reduce the availability. The aim of the present study was to assess the feasibility of UCB collection in neonates at increased risk of brain damage. Infants from four high-risk groups were included: newborns with perinatal hypoxemia, gestational age (GA) ≤30 + 0 weeks and/or birthweight <1,500 g, intrauterine growth restriction (IUGR), or monochorionic twins with twin-to-twin transfusion syndrome (TTTS). Feasibility of collection, quantity and quality of obtained UCB [total nucleated cell count (TNC), volume, sterility, and cell viability], and neonatal outcome were assessed. UCB collection was successful in 141 of 177 enrolled patients (hypoxemia n = 10; GA ≤30 + 0 weeks n = 54; IUGR n = 71; TTTS n = 6). Twenty-six cases were missed. The amount of missed cases per month declined over the time. Volume of collected UCB ranged widely (median: 24.5 ml, range: 5.0–102 ml) and contained a median of 0.77 × 108 TNC (range: 0.01–13.0 × 108). TNC and UCB volume correlated significantly with GA. A total of 10.7% (19/177) of included neonates developed brain lesions. To conclude, collection of UCB in neonates at high risk of brain damage is feasible with a multidisciplinary approach and intensive training. High prevalence of brain damage makes UCB collection worthwhile. Collected autologous UCB from mature neonates harbors a sufficient cell count for potential therapy. However, quality and quantity of obtained UCB are critical for potential therapy in preterm infants. Therefore, for extremely preterm infants alternative cell sources such as UCB tissue should be investigated for autologous treatment options because of the low yield of UCB.

Abstract
Fetal therapy term has been described for any therapeutic intervention either invasive or noninvasive for the purpose of correcting or treating any fetal malformation or condition. Fetal therapy is a rapidly evolving specialty and has gained pace in last two decades and now fetal intervention is being tried in many malformations with rate of success varying with the type of different fetal conditions. The advances in imaging techniques have allowed fetal medicine persons to make earlier and accurate diagnosis of numerous fetal anomalies. Still many fetal anomalies are managed postnatally because the fetal outcomes have not changed significantly with the use of fetal therapy and this approach avoids unnecessary maternal risk secondary to inutero intervention. The short-term maternal risk associated with fetal surgery includes preterm labor, premature rupture of membranes, uterine wall bleeding, chorioamniotic separation, placental abruption, chorioamnionitis, and anesthesia risk. Whereas, maternal long-term complications include risk of infertility, uterine rupture, and need for cesarean section in future pregnancies. The decision for invasive fetal therapy should be taken after discussion with parents about the various aspects like postnatal fetal outcome without fetal intervention, possible outcome if the fetal intervention is done, available postnatal intervention for the fetal condition, and possible short-term and long-term maternal complications. The center where fetal intervention is done should have facility of multi-disciplinary team to manage both maternal and fetal complications. The major issues in the development of fetal surgery include selection of patient for intervention, crafting effective fetal surgical skills, requirement of regular fetal and uterine monitoring, effective tocolysis, and minimizing fetal and maternal fetal risks. This review will cover the surgical or invasive aspect of fetal therapy with available evidence and will highlight the progress made in the management of fetal malformations in last two decades.

Abstract
OBJECTIVE To assess the cardiac function and prevalence of congenital heart defects (CHD) in twin-twin transfusion syndrome (TTTS) survivors. STUDY DESIGN Prospective follow-up of TTTS pregnancies treated with laser surgery (2015-2018). Echocardiography was performed 1 day and 1 month after birth (corrected for prematurity). Results were compared with a control group of age-matched uncomplicated monochorionic twin-pairs at 1 month. RESULT Eighty-nine TTTS (168 neonates) and nine control pregnancies (18 neonates) were enrolled. CHD birth prevalence was 9.2% (8/87) in recipients and 13.6% (11/81) in donors (p = 0.37). Four of 19 (21%) were detected prenatally, all pulmonary stenosis. Donors had lower aortic peak velocities compared with recipients at day 1 (0.66 ± 0.15 m/s vs 0.71 ± 0.19 m/s, p = 0.04) and 1 month (1.04 ± 0.21 m/s vs 1.11 ± 0.18 m/s, p = 0.02), but not compared with controls. CONCLUSION CHD prevalence in TTTS survivors is high, with a low prenatal detection of minor abnormalities. Follow-up fetal echocardiograms and a postnatal echocardiogram should be offered.

Abstract
Background Fetal conditions can pose significant challenges in the management of pregnancies complicated by pre-existing maternal medical conditions. Case presentation We report a case of a 34-year-old woman with Stage IV Twin Twin Transfusion syndrome in the presence of maternal recurrent complex venous thromboembolic disease. Following a previous pregnancy loss, complicated by a third episode of thromboembolic disease, an inferior vena cava filter was placed. One month later, a pregnancy was confirmed and subsequently identified as a monochorionic twin pregnancy. Twin-Twin Transfusion syndrome was identified at 18 weeks’ gestation and progressed rapidly to Quintero Stage IV. In consultation with a multi-disciplinary international team, fetoscopic laser photocoagulation was performed. The pregnancy progressed to delivery of female infants at 33 weeks gestation, who have achieved all developmental milestones at 2 years of age. Conclusions We describe the multi-disciplinary effort to optimise the maternal condition to allow fetoscopic laser photocoagulation and continued management of the maternal and fetal conditions to a successful pregnancy outcome.

Neonatal Outcomes and Maternal Characteristics in Monochorionic Diamniotic Twin Pregnancies: Uncomplicated versus Twin-to-Twin Transfusion Syndrome Survivors after Fetoscopic Laser Surgery. Fetal Diagn Ther 2019; 47:165-170.

Abstract
Preterm birth remains a major complication of fetal laser surgery (FLS) due to twin-to-twin transfusion syndrome (TTTS). OBJECTIVES We tested the hypothesis that neonatal outcomes in fetuses born at >24 weeks are worse in TTTS survivors compared to uncomplicated monochorionic diamniotic (MCDA) twins. METHODS 196 patients with TTTS treated with laser therapy and 91 uncomplicated MCDA gestations were compared. Neonatal outcomes included respiratory distress syndrome (RDS), transient tachypnea of the newborn (TTN), bronchopulmonary dysplasia, intraventricular hemorrhage, necrotizing enterocolitis, and neonatal death. Risk factors assessed were TTTS, maternal age, maternal body mass index, race, premature prolonged rupture of membranes, stage of TTTS, parity, and gestational age (GA) at delivery. RESULTS GA at delivery was lower in the TTTS group (31.0 ± 4.6 vs. 33.5 ± 2.4 weeks, p < 0.001). RDS and TTN occurred at higher rates in the TTTS than in the uncomplicated MCDA group. After multivariate logistic regression, the only factor significantly associated with the composite adverse outcome was GA at delivery (OR 0.61; 95% CI: 0.58-0.7). CONCLUSION TTTS twins treated with FLS are deliver 2.5 weeks earlier than uncomplicated MCDA twins. Respiratory complications were significantly higher in TTTS twins and were mainly the consequence of the early GA at delivery.

Abstract
BACKGROUND Amongst other sequelae, acute kidney injury (AKI) is a well-recognised post-natal complication of twin-to-twin transfusion syndrome (TTTS). Despite this, there has been a lack of data reporting long-term renal outcomes. Our aim was to report the long-term renal outcomes of infants born with TTTS. METHODS We performed a retrospective case note review of all infants referred to our centre between 1998 and 2018 with a primary diagnosis of TTTS. Subjects with confirmed TTTS were divided into a chronic kidney disease (CKD) group and a non-CKD group for comparison. RESULTS Twenty-six infants with TTTS were included for analysis. Eight (31%) subjects developed CKD. Within the CKD group, 50% went on to require long-term renal replacement therapy (RRT) of whom all underwent renal transplantation. For subjects who had neonatal AKI, cumulative survival rate before RRT at 5 and 10 years was 79% and 70%, respectively. Subjects with CKD had a significantly higher incidence of AKI in the neonatal period and were more likely to be the donor twin. Gestational age at birth, gender, antenatal interventions and comorbidities did not affect long-term renal outcome between the two groups. CONCLUSION This is the first long-term follow-up study demonstrating that CKD progressing to the need for RRT can develop after TTTS. Donor-twin status and neonatal AKI associated with adverse long-term outcomes warranting long-term surveillance in this group.

Abstract
PURPOSE To present a case of twin-to-twin transfusion syndrome (TTTS), followed by discussion of the etiology, pathophysiology, prenatal diagnosis, management, complications, prognosis, and family considerations. METHODS A literature review was conducted using MEDLINE, PubMed, CINAHL, ProQuest, and Google Scholar. The search resulted in 593 articles; 25 relevant articles were chosen. RESULTS Approximately 1 of every 250 cases of monochorionic twins acquire TTTS. The progression of TTTS is unpredictable; nontreatment and early onset have been associated with >90 percent mortality of both twins. Neurodevelopmental impairment, preterm birth, renal hypoperfusion, growth restriction, cardiomyopathy, and hydrops fetalis have been associated with TTTS. LIMITATIONS A paucity of research and case reports exists, limiting recommendations for optimal diagnosis, management, and treatment regimens. IMPLICATIONS FOR PRACTICE TTTS is unpredictable in progression; earlier identification of chorionicity, diagnosis of TTTS, and improvement of treatment and management have the potential to improve the mortality and morbidity outcomes associated with TTTS.

Abstract
OBJECTIVE To compare perinatal outcomes between acute single fetal demise following fetoscopic laser photocoagulation to planned selective reduction (SR) in complicated monochorionic twin pregnancies. METHODS This was a secondary analysis of prospectively collected data in complicated monochorionic twin pregnancies from 2 fetal centers from 2011 to 2016. Group 1 included women undergoing fetoscopic laser photocoagulation for twin-twin transfusion syndrome (TTTS) who experienced a single fetal demise within 24 hours of the procedure. Group 2 consisted of women undergoing planned selective reduction (SR) with TTTS, and Group 3 SR for indications other than TTTS. RESULTS Survival of the remaining co-twin at birth was highest in Group 1 (n = 77 patients; 95%) compared with that in Group 2 (n = 15; 80%) and Group 3 (n = 32; 78%; P = .047). The preterm premature rupture of membrane rate was higher in Group 1 (47%) compared with that in Group 2 (33%) and Group 3 (7%; P < .001). Group 1 had a lower gestational age at delivery and shorter procedure-to-delivery interval compared with the other 2 groups (P < .01). CONCLUSION When single fetal demise occurs following fetoscopic laser photocoagulation, the surviving co-twin is more likely to survive to delivery but has higher PPROM rates and a shorter latency period compared with planned selective reduction for TTTS or other indications.

Abstract
Fetoscopic laser coagulation of arterio-venous anastomoses (AVA) in a monochorionic placenta is the standard of care for twin-twin transfusion syndrome (TTTS), but is technically challenging and can lead to significant complications. Acquiring and maintaining the necessary surgical skills require consistent practice, a critical caseload, and time. Training on realistic surgical simulators can potentially shorten this steep learning curve and enables several proceduralists to acquire procedure-specific skills simultaneously. Here we describe realistic simulators designed to allow the user familiarity with the equipment and specific steps required in the surgical treatment of TTTS, including fetoscopic handling, approaches to anterior and posterior placenta, recognition of anastomoses, and efficient coagulation of vessels. We describe the skills that are especially important in conducting placental laser coagulation that the surgeon can practice on the model and apply in a clinical case. These models can be adapted easily depending on the availability of materials and require standard fetoscopy equipment. Such training systems are complementary to traditional surgical apprenticeships and can be useful aids for fetal medicine units that provide this clinical service.

Abstract
INTRODUCTION Management of complicated monochorionic twins and certain intrauterine structural anomalies is a pressing challenge in communities that still lack advanced fetal therapy. We describe our efforts to rapidly initiate selective feticide using radiofrequency ablation (RFA) and selective fetoscopic laser photocoagulation (SFLP) for twin-to-twin transfusion syndrome (TTTS), and present the latter as a potential model for aspiring fetal therapy units. METHODS Five pregnancies with fetal complications were identified for RFA. Three pregnancies with Stage II TTTS were selected for SFLP. While RFA techniques utilising ultrasonography skills were quickly mastered, SFLP required stepwise technical learning with an overseas-based proctor, who provided real-time hands-off supervision. RESULTS All co-twins were live-born following selective feticide; one singleton pregnancy was lost. Fetoscopy techniques were learned in a stepwise manner and procedures were performed by a novice team of surgeons under proctorship. Dichorionisation was completed in only one patient. Five of six twins were live-born near term. One pregnancy developed twin anaemia-polycythaemia sequence, while another was complicated by co-twin demise. DISCUSSION Proctor-supervised directed learning facilitated the rapid provision of basic fetal therapy services by our unit. While traditional apprenticeship is important for building individual expertise, this system is complementary and may benefit other small units committed to providing these services.

Abstract
Fetal therapy is an exciting and growing field of medicine. Advances in prenatal imaging and continued innovations in surgical and anesthetic techniques have resulted in a wide range of fetal interventions including minimally invasive, open mid-gestation, and ex-utero intrapartum treatment procedures. The potential for maternal morbidity is significant and must be carefully weighed against claimed benefits to the fetus. Appropriate patient selection is critical, and a multidisciplinary team-based approach is strongly recommended. The anesthetic management should focus on maintaining uteroplacental circulation, achieving profound uterine relaxation, optimizing surgical conditions, monitoring fetal hemodynamics, and minimizing maternal and fetal risk.

Abstract
OBJECTIVE To measure amniotic fluid leptin levels in fetuses with twin-twin transfusion syndrome (TTTS) with and without placental insufficiency (PI) and determine its usefulness as a biomarker of PI. STUDY DESIGN A retrospective case control study of TTTS stage III patients from 2009 to 2011 was conducted. Cases were pregnancies with PI (TTTS-PI, n = 18) matched by stage, gestational age, and degree of cardiomyopathy to controls without PI (TTTS, n = 26). PI was strictly defined using biometric parameters. Amniotic fluid from recipient twins (RT) was taken during second trimester fetoscopic laser therapy. Leptin concentrations were determined and compared to growth parameters and birth weight. RESULTS RT-adjusted leptin was 66% higher in TTTS-PI (p = 0.016) compared to TTTS controls. Cases had significantly higher growth discordance (p = 0.004) and lower RT birth weight (p = 0.041) compared to controls. Significantly higher adjusted leptin levels were observed at birth in the TTTS-PI group when comparing those with SGA donor twins to those of normal weight (p = 0.016). CONCLUSION These data suggest a role for leptin in pregnancies complicated by TTTS with placental insufficiency. However, further studies are needed to define its mechanism and potential role as a biomarker in amniotic fluid for placental pathophysiology.

Abstract
BACKGROUND Epigenetic mechanisms are thought to be critical in mediating the role of the intrauterine environment on lifelong health and disease. Twin-twin transfusion syndrome (TTTS) is a rare condition wherein fetuses share the placenta and develop vascular anastomoses, which allow blood to flow between the fetuses. The unequal flow results in reciprocal hypo- and hypervolemia in the affected twins, striking growth differences and physiologic adaptations in response to this significant stressor. The donor twin in the TTTS syndrome can be profoundly growth restricted and there is likely a nutritional imbalance between the twins. The consequences of TTTS on fetal programming are unknown. This condition can now be effectively treated through the use of fetal laparoscopic procedures, but the potential for lifelong morbidity related to this condition during development is apparent. As this condition and the resulting uteroplacental discordance can play a role in the epigenetic process, we sought to investigate the DNA methylation profiles of childhood survivors of TTTS (n = 14). We focused on differences in both global measures and genome-wide CpG specific DNA methylation between donor and recipient children in this pilot study in order to generate hypotheses for further research. RESULTS We identified significant hypomethylation of the LINE1 repetitive element in the peripheral blood of donor children and subtle variation in the genome-wide profiles of CpG specific methylation most prominent at CpG sites which are targets for polycomb group repressive complexes. CONCLUSIONS These preliminary results suggest that coordinated epigenetic alterations result from the intrauterine environment experienced by infants with TTTS and may, at least in part, be responsible for downstream health conditions experienced by individuals surviving this condition.

Abstract
AIM To investigate the characteristics of twin pregnancies and their mode of delivery over a 30-year period, in order to define the current trends in clinical practice regarding twin deliveries and the factors that influence these practices. MATERIALS AND METHODS A retrospective study of twin deliveries at ≥24 weeks of gestation between January 1st, 1981 and December 31, 2010. Data concerning number of twin deliveries, mode of delivery, maternal age, use of ART techniques, parity, gestational age at delivery, birth weight and Apgar scores were collected from labor ward records. RESULTS Over the years there has been a statistically significant increase in the number of twin deliveries, twins after IVF, cesarean section rate, maternal age, nulliparity and a statistically significant reduction in term deliveries, mean birth weight and assisted vaginal deliveries. Maternal age, gestational age, parity and conception after IVF are factors related to the risk of performing a cesarean section. CONCLUSIONS Despite the lack of adequate scientific evidence concerning the optimal route of delivery in twin pregnancies it seems that over time cesarean section has become the standard of care in most of twin pregnancies. Changes in the demographic characteristics contribute among other factors to this practice.

Abstract
AIM The aims of the study were to compare perinatal outcome and assess recipient cardiac disease according to treatment strategy (amnioreduction (AR), laser or selective feticide). METHODS We retrospectively reviewed 81 consecutive cases of twin-to-twin transfusion syndrome diagnosed before 28 weeks between 1993 and 2007. RESULTS Although fetuses treated by laser were younger at diagnosis (median 20.4 vs. 22.4 weeks, P = 0.01), they were significantly older at birth (median 33.6 vs. 28.5 weeks, P = 0.004) than those treated by AR. Neonatal morbidity was globally lower after laser than AR, and cardiac insufficiency tended to be less frequent (31% vs. 57%, P = 0.09). There was a trend towards increased perinatal survival after laser treatment (68% vs. 49%, P = 0.1). Heart failure was the cause of death in half (23/46) of the recipients. Fetal heart failure leading to death was 2.7 times more frequent after AR than after laser (n = 11 vs. n = 4), and all four neonatal cardiac deaths occurred after AR. Compared with laser, selective feticide did not further improve the outcome. CONCLUSIONS Heart failure was an important cause of perinatal morbidity and death. However, laser therapy resulted in a longer diagnosis-delivery interval and lower global neonatal morbidity than AR, with a trend towards increased perinatal survival. Improved outcome after laser treatment compared with AR might be related to its impact on recipient heart disease.

Abstract
We describe a rare case of multiple intestinal atresias, congenital bilateral perisylvian polymicrogyria, and chronic pulmonary hypertension in a surviving monochorionic twin with co-twin demise. This constellation of congenital anomalies represents a multiple vascular disruption syndrome due to intrauterine vascular compromise in the setting of possible twin-to-twin transfusion syndrome.

Abstract
'Starry sky' liver is one of the most common sonographic patterns in diffuse liver disease. It is characterized by clearly identified portal venules due to diminished parenchymal echogenicity. In advanced cases of twin-to-twin transfusion syndrome (TTTS), volume overload is considered the key factor in the pathogenesis of cardiac dysfunction of the recipient twin. When right-sided failure occurs, the liver might show signs of edema and, as in acute hepatitis, the appearance of starry sky might develop. We present a case in which the sonographic appearance of starry sky liver, along with right-sided cardiac failure (tricuspid regurgitation), were the first signs of TTTS in monochorionic twins at 20 weeks. A short time later, at 21 weeks, other signs of overload and signs of worsening heart failure were noted, as the typical triphasic waves in the inferior vena cava were replaced by a biphasic flow profile. Twin 2 at that time had relative oligohydramnios. A few days later, relative polyhydramnios and edema of the placental domain of the recipient twin were also noted. To the best of our knowledge, this is the first case report describing this hepatic sonographic pattern as an early sonographic sign of TTTS.

Abstract
BACKGROUND AND PURPOSE Neurodevelopmental disability is common in twins with TTTS in utero; however, the responsible neuropathology remains uncertain. We proposed to document the frequency of brain abnormalities on clinical fetal MR images and to determine if quantitative fetal brain biometric analysis in twin fetuses with TTTS was different from those in healthy control fetuses. MATERIALS AND METHODS We reviewed the fetal brain MR images of 33 twin pairs with TTTS clinically evaluated in our institution. Eighteen fetal MR images of "healthy" twins with TTTS were further studied with biometric analysis in comparison with GA-matched singleton fetuses to detect quantitative differences in brain growth and development. RESULTS A higher incidence of anomalies (11/33, 33.3%) was found than previously reported. The most frequent abnormality was ventriculomegaly (7/11, 63%) in both donor and recipient. In "healthy" twins with TTTS, biometric analysis revealed persistently small measurements (cBTD, CMT, TCD, and VAPD) in the donor cerebrum and cerebellum in comparison with their recipient cotwin and healthy control fetuses. These differences were preserved when normalized by cBTD. CONCLUSIONS Our findings show that significant brain abnormalities are common in TTTS. In addition, diffuse subtle abnormalities are also present in normal-appearing donor fetal brains that cannot be solely explained by overall growth restriction. Such subtle fetal brain anomalies may explain the high incidence of poor long-term neurodevelopmental outcomes of survivors, and they need to be further investigated with more sophisticated quantitative fetal imaging methodologies.

Abstract
We present the clinical presentation and pathological findings from a term infant with atypical neonatal lung disease. A full term Caucasian male presented at birth with signs of respiratory distress. The respiratory condition continued to deteriorate despite maximum intervention and the patient was placed on ECMO for further cardiorespiratory assistance. An open lung biopsy demonstrated findings consistent with severe lung growth abnormality with non-uniform pulmonary interstitial glycogenosis. The patient consequently developed a pulmonary hemorrhage that required discontinuation of ECMO. The patient died shortly after decannulation. Most literature suggests that PIG is one of the few pediatric interstitial lung diseases that has a favorable prognosis with rare mortality in the absence of co-morbidities. However, the current case suggests prognosis may depend more on the underlying diagnosis than on the histological finding of PIG. In addition, this case may provide insight into the pathogenesis and potential modifiers of this idiopathic disorder.

Abstract
OBJECTIVE To evaluate the incidence and clinical outcome of inadvertent septostomy after fetoscopic laser therapy for twin-twin transfusion syndrome (TTTS) and, particularly, to explore its association with the risk of developing pseudoamniotic band syndrome (PABS). METHODS In a cohort of 414 consecutive monochorionic twin pregnancies with confirmed TTTS treated with laser, the incidence of postoperative septostomy within 1 week of the procedure was recorded prospectively. Rates of preterm delivery, preterm premature rupture of membranes (PPROM), intrauterine fetal demise (IUFD) and PABS were compared among cases with and without septostomy. RESULTS The mean gestational age at laser therapy was 20.4 (range, 15.3-27.6) weeks. Postoperative septostomy occurred in 30 (7.2%) cases. Pregnancies complicated with septostomy had a significantly higher proportion of preterm delivery before 32 weeks (76.7% vs. 30.2%, P < 0.001), PPROM before 32 weeks (46.7% vs. 19.0%, P < 0.001), IUFD (43.3% vs. 25.8%, P < 0.05) and PABS (13.3% vs. 1.0%, P < 0.001), compared with pregnancies without septostomy. CONCLUSIONS Inadvertent septostomy occurred in 7% of cases after fetoscopic laser therapy and was associated with a substantially increased risk of adverse perinatal outcome and PABS.

Abstract
Fetal echocardiography was initially used to diagnose structural heart disease, but recent interest has focused on functional assessment. Effects of extracardiac conditions on the cardiac function such as volume overload (in the recipient in twin-twin transfusion syndrome), a hyperdynamic circulation (arterio-venous malformation), cardiac compression (diaphragmatic hernia, lung tumours) and increased placental resistance (intrauterine growth restriction and placental insufficiency) can be studied by ultrasound and may guide decisions for intervention or delivery. A variety of functional tests can be used, but there is no single clinical standard. For some specific conditions, however, certain tests have shown diagnostic value.

Abstract
OBJECTIVE To determine preoperative predictive factors for donor and recipient death after laser ablation of placental vessels in twin-to-twin transfusion syndrome. STUDY DESIGN Retrospective analysis of North American Fetal Therapy Network center laser procedures, 2002-2009. Factors associated with donor and recipient death were identified by regression analysis. RESULTS There were 466 patients from 8 centers. Factors significantly associated with donor fetal death were low donor estimated fetal weight (odds ratio [OR], 0.69; 95% confidence interval [CI], 0.55-0.87) and reversed end diastolic velocity in the umbilical artery (OR, 4.0; 95% CI, 1.54-10.2); for recipient fetal death-low recipient estimated fetal weight (OR, 0.65; 95% CI, 0.44-0.95), recipient reversed "a" wave in the ductus venosus (OR, 2.39; 95% CI, 1.27-4.51) and hydrops (OR, 3.7; 95% CI, 1.1-12.7); for recipient neonatal death-low donor estimated fetal weight (OR, 0.54; 95% CI, 0.30-0.95), high recipient estimated fetal weight (OR, 1.55; 95% CI, 1.06-2.26) and recipient reversed end diastolic velocity in the umbilical artery (OR, 7.8; 95% CI, 1.03-59.3). CONCLUSION Preoperative findings predict fetal and neonatal demise in twin-to-twin transfusion syndrome treated with laser therapy.

Abstract
OBJECTIVE The purpose of this study was to evaluate the effect of maternal nifedipine on fetal survival when started 24-48 hours before selective fetoscopic laser photocoagulation (SFLP). STUDY DESIGN We conducted a case control study of consecutive cases of twin-twin transfusion syndrome (TTTS) in which TTTS cardiomyopathy was treated with maternal nifedipine 24-48 hours before SFLP, compared with gestational age and stage-matched control cases. The primary outcome was recipient and donor survival. RESULTS One hundred forty-one cases of TTTS were treated with nifedipine, and 152 gestational age- and stage-matched control cases were analyzed. There was a significant increase in overall fetal survival in nifedipine-treated cases compared with control cases (237/284 [83%] vs 232/308 [75%]; P = .015). There is an increase in survival of recipients who were treated with nifedipine in stage IIIA (100% vs 81%; P = .021) and IIIB (93% vs 71%; P = .014); however, there was no difference in donor survival. CONCLUSION Maternal nifedipine is associated with improved recipient survival in TTTS that undergoes SFLP. This is the first study to suggest a benefit of adjunctive maternal medical therapy in patients with TTTS who undergo SFLP.

Abstract
INTRODUCTION Neonatal polycythemia may result in increased cytokine production. We aimed to investigate whether polycythemia and partial exchange transfusion (PET) affect interleukin-6 (IL-6) response pattern in early neonatal period. METHODS Ninety-four newborns, 57 with polycythemia (Group 1) and 37 as control group (Group 2) were enrolled in the study. PET was performed at 4-6 hr following birth in the first group. Blood levels of IL-6 were measured at 2-4 hr following birth; measurements were repeated at 6 and 24 hr after PET in newborns with polycythemia and at similar hours in Group 2. In Group 1, two patients (3.5%) who were diagnosed with proven sepsis excluded from the study. RESULTS Both initial and the last IL-6 levels were higher in Group 1 (21.7; 5.5-190 pg/ml and 18.3; 2.7-92.4 pg/ml) than those of the controls (8.4; 0.2-47.8 pg/ml and 8.6; 2.0-21.0 pg/ml) (P=0.001 for both comparisons). In Group 1, IL-6 levels increased at 6 hr after PET and decreased thereafter. IL-6 showed the same pattern in the control group. IL-6 levels were higher than >70 pg/ml in two (3.6%), seven (12.7%), and two (3.6%) subjects during three evaluation steps, respectively. Neither clinical nor proven sepsis was subsequently detected in any of these subjects. IL-6 levels were within the acceptable values in Group 2. CONCLUSION IL-6 levels seem to be high in newborns with polycythemia during the first days of life, although they rarely exceed maximum acceptable levels. The pattern of IL-6 response might be taken into account to optimize its use in the diagnosis of early-onset neonatal sepsis.
