Filter by:Open maternal-fetal surgery is currently used on fetuses with myelomeningocele (MMC). Fetoscopic or minimal access fetal surgery is also being used to treat fetuses with congenital diaphragmatic hernia (CDH). Following accurate diagnosis of a congenital malformation such as MMC or CDH, prospective parents face a range of uncertainties regarding the future of their unborn child, and the options provided require major ethical considerations. In the situation under study, termination of pregnancy may be for some parents an alternative option to expectant prenatal management. Fetal therapy provides a tantalising third option for some, where procedures are undertaken to reduce the likelihood of a more complicated neonatal course, potentially improving long term outcome, but at risk of amniotic fluid leakage, infection and most importantly very preterm delivery, itself associated with significant neonatal mortality and morbidity and long-term consequences. Balancing these competing risks is challenging. For an intervention to be effective it also needs to be acceptable to women and their families. "Acceptability" can be defined as a multi-faceted construct that reflects the extent to which people delivering or receiving a healthcare intervention consider it to be appropriate, based on anticipated or experienced cognitive and emotional responses to the intervention. With this study it is the aim to assess how women (and their partners) perceive the acceptability of a fetal surgical intervention for MMC and CDH. Participants will be asked to share their thoughts, views, feelings and experiences with regards to the decision to participate in fetal surgery. Data are collected by the use of in-depth face-to-face interviews. In-depth interviews are used to understand the participant's perspectives and perceptions of a situation they are in. It explicitly includes participants interpretation and understanding of an event The interviews will be held in two or three moments in time (for parents opting for fetal surgery, there will be one additional interview, after the intervention while admitted in hospital): after counselling for options, but before eventual intervention; for intervention group shortly after the intervention, and 12 weeks after birth of the baby, or termination of pregnancy.
We wish to use the images a mother would have done as part of her normal medical care and make both 3D animations and 3D models of the baby and it's CDH. This will both help the parents see what the problem is and also allow the surgeons, who will operate on the baby once it has been born, to see the size of the hole and what organs are in the wrong place.
The purpose of this research study is to see if the FETO surgery and FETO release (surgery to remove the device) works and is safe for babies with severe right or left Congenital Diaphragmatic Hernia (CDH). CDH is a condition in which a hole in the baby's diaphragm allows the abdominal organs to move into the chest and limit lung growth. The goal of the FETO device is to block the airway with a balloon-type device, allowing fluid to build up and help the unborn baby's lungs grow. Bigger lungs may improve the baby's quality of life.
The purpose of this study is to investigate the use of autologous umbilical cord blood (UCB) mononuclear cells to mitigate hypoxic neurologic injury among infants with high-risk congenital diaphragmatic hernia (CDH).
Congenital diaphragmatic hernia (CDH) has an incidence of 1:2200 to 1:4000 newborns. The survival rate depends on the extent of the lung hypoplasia and pulmonary hypertension. In case of an observed / expected total fetal lung volume ratio (o/e TFLV) ratio of 25% or lower and herniation of the liver in thorax, the postnatal survival is estimated to be 10-25% or lower. The aim of fetoscopic tracheal balloon occlusion is to positively influence the lung growth in CDH fetuses avoiding the development of lung hypoplasia. Some complications after sucsessfull FETO before delivery occur because of technical difficulties during the extraction of the balloon from the trachea, leading to asphyxia, worse outcome or neonatal demise. Jani et al. published 10 neonatal deaths from 210 FETO directly related to difficulties with the removal of the intratracheal balloon. The risk of emergent balloon removal was published to be very high (39%-56%). Our new technique exploits the fetal ability to removal the intratracheal balloon which has been implanted for the treatment of severe CDH before the delivery, avoiding many risks associated with balloon extraction and a second fetoscopy. The study will be performed on 20 fetuses with severe CDH. Before the FETO the total fetal lung volume ratio (o/e TFLV) will be measured by fetal MRI (magnetic . Only CDH fetuses with 24-32 weeks' gestation with o/e TFLV < 25% or the fetuses with o/e TFLV < 35% and liver herniation will be operated Second fetal MRI should be performed in one week after the FETO. The balloon will be extracted by the fetus itself before the delivery, after puncture with 22 gauge needle under ultrasound guiding, during second fetoscopy or using the EXIT (ex utero intrapartum Treatment). Neonatal follow up 12 months.
Congenital diaphragmatic hernia (CDH) is a severe congenital malformation, related to a developmental defect of the diaphragm. The incidence of CDH is approximated at 1 in 3,000 live births. Although advances in surgery and neonatal intensive care have improved the prognosis, mortality remains high, around 30-50% related to severe lung hypoplasia and persistent pulmonary hypertension. Prenatal evaluation with observed/expected Lung over Head Ratio (o/e LHR), liver position and total lung volume measured by magnetic resonance, have been shown to correlate with neonatal mortality . However, the preponderant factor of persistent pulmonary hypertension remains difficult to predict prenatally. In patients with isolated diaphragmatic hernia (without associated malformations or karyotype abnormalities), prognosis is evaluated indirectly on pulmonary development from pulmonary volume measurements. Apart from the most caricatural cases with extremely good or very pejorative values, for a large proportion of fetuses with diaphragmatic dome hernia the prognosis remains uncertain. The aim of the proposal is to investigate whether the analysis of the proteom of the amniotic fluid of the fetuses with CDH could give information of a prognostic character. The objective of the study is to identify, from the proteomic profile of the amniotic fluid of mothers whose fetus has CDH, prognostic markers candidates for death at 2 months of the infant. The first step is to carry out an exploratory and non-interventional study on a small sample (n = 10) of the target population. This is a preliminary step before considering, if the results are encouraging, a large-scale study from a biological collection to determine candidate proteins (new biomarkers) which relative expression levels could be used as surrogate marker of pulmonary hypoplasia.
The purpose of this research is to gather information on the safety and effectiveness of a new procedure called Fetoscopic Endoluminal Tracheal Occlusion (FETO).
Tracheal occlusion IDE approved by FDA for congenital diaphragmatic hernia fetuses.
To determine the appropriate volume (size) of ventilator breath during volume-targetted ventilation for infants born with congenital diaphragmatic hernia.
Despite advances in prenatal diagnosis and postnatal therapies, including extracorporeal membrane oxygenation (ECMO), inhaled nitric oxide therapy, and ventilator strategies that minimize ventilator-induced lung injury, morbidity and mortality rates for babies with congenital diaphragmatic hernia (CDH) remain high. The survival relates to the degree of prenatal lung compression and the subsequent impairment of pulmonary function following delivery. Prenatal assessment by ultrasound or magnetic resonance imaging allows to estimate the severity by relating the circumference of the lung contralateral to the hernia to the fetal head circumference lung to head ratio (LHR) and by noting the degree of upward herniation of the liver. Based on the observed to expected lung to head ratio (O/E LHR), prenatally diagnosed congenital diaphragmatic hernia can be prognostically assessed. While overall survival of congenital diaphragmatic hernia is approximately 60%, an O/E LHR <25% is associated with survival between 11-24%. The rationale for fetal therapy in severe congenital diaphragmatic hernia is to restore adequate lung growth for neonatal survival. Prenatal tracheal occlusion obstructs the normal egress of lung fluid during pulmonary development leading to increased lung tissue stretch, increased cell proliferation, and accelerated lung growth. European colleagues have developed intrauterine endoscopic techniques (fetoscopy) to position and remove endoluminal tracheal balloons in utero (fetoscopic endotracheal occlusion = FETO). Recently, the Belgium group published summary results of FETO showing an improved survival in 175 patients with isolated left CDH from 24% to 49%. We hypothesize that FETO can be performed and may increase survival and decrease morbidity when compared to standard prenatal care for the treatment of severe CDH in the most severe group of fetuses with left CDH (O/E LHR < 30%). FETO therapy will be considered in two subgroups: those with and O/E LHR <25% (severe group) and those with an O/E between 25 to <30% (less severe group).
