Other factors that may have influenced perinatal survival include variations in procedure, and in maternal and fetal characteristics however, these factors were shown to have no significant effect in the univariate logistic regression model analysis. Intervention for cardiac defects fits into existing fetal care structures  and is an extension of services and clinical research protocols related to fetal treatment however, it is still largely considered an adjunct to optimal postnatal management and does not obviate the need for further intervention after birth. Some 35 of the 45 women who underwent fetal surgery for cdh in utero followed by an exit procedure attempted a further pregnancy and 31 had subsequent live births in the series by bouchard and co-workers (bouchard et al 2002 bouchard s , johnson mp , flake aw .
Open fetal surgery is similar in many respects to a normal cesarean section performed under general anesthesia, except that the fetus remains dependent on the placenta and is returned to the uterus a hysterotomy is performed on the pregnant woman, and once the uterus is. Over the past 3 decades, fetal surgery for congenital disease has evolved from merely a fanciful concept to a medical field in its own right techniques for open hysterotomy, minimal-access hysteroscopy, and image-guided percutaneous fetal access have become well established, first in animal models and subsequently in humans. The american college of radiology will periodically define new practice guidelines and technical standards for radiologic practice to help advance the specific procedure or course of action must be made by fetal surgery, mri is a useful adjunct in confirming the diagnosis and planning potential surgical options [37,60.
Fetal cardiac intervention is an invasive procedure performed to treat the fetus while the anesthetized mother who undergoes surgery is solely a bystander the procedure is without direct benefit to her and thus is an altruistic act by the mother on behalf of her unborn child. Open fetal surgery is possible first after approximately 18 weeks of gestation due to fetal size and fragility before that, and up to approximately 30 weeks of gestation due to increased risk of premature labor and, practically, the preference for delivering the child and. Fetal conditions that have been identified as responsive to surgical intervention encouraged the foundation in 1983 of the international fetal medicine and surgery society which supports the efforts of those involved in the emergent medical specialty of fetal surgery. 1 introduction fetal surgery is a rapidly evolving discipline the idea of treating the fetus as a patient is not intuitive and has its roots in the 1960s when intraperitoneal blood transfusions were performed for the treatment of erythroblastosis fetalis.
Fetal surgery roy kimble: consultant paediatric surgeon, royal children’s hospital, brisbane introduction: this chapter provides an overview of fetal surgery fetal surgery is a relatively new specialty and should be regarded as mainly experimental. Magnetic resonance imaging and fetal surgery us is the primary imaging modality for fetal assessment, because of its proven utility, relatively low cost, and widespread availability advantageous imaging characteristics of us include multiplanar capability, availability of doppler us to depict flow, high spatial resolution, and real-time display. Introduction there are a number of conditions detected by prenatal diagnostic techniques that can now be treated by fetal surgery open fetal surgery - a major procedure involving a cesarean section, partial removal of the fetus for surgery, followed by return to the uterus relatively rare condition, about 1 in 40,000 fetuses.
For these procedures, the uterus is exposed for a mean of 30 minutes, and each fetal surgical procedure involves opening the uterus and holding the caudal end of the fetus exposed for a mean of 12 minutes this time being shorter, in general, for male fetuses and slightly longer for female fetuses even a relatively mild stress can cause. Furthermore, with an exit procedure there is risk of a malpositioned endotracheal tube, failure to secure an airway (requiring emergent neonatal surgery), or fetal death (9,16,64) conclusions until recently, the prognosis for fetuses and neonates at risk for airway obstruction at birth has been dismal. Introduction surgery for congenital heart disease surgery is performed considerably earlier than it was twenty years ago, often in the first months after birth cardiac therapy is a relatively new fetal therapy specialised obstetricians working in fetal hybrid procedure (18) would be offered to a baby less than 30 weeks gestation in. Surgery for congenital heart disease is now often performed in the first months of life because mortality is higher and myocardial damage more serious in unoperated children or those undergoing delayed surgery fetal cardiac intervention may prove a logical extension and has been proposed for.
Preterm labor is the most common complication of open fetal surgery, with an average gestational age at delivery of 34 weeks and mean duration of 10 weeks from surgery to delivery in one series fetoscopic surgery. Fetal surgery is a specialty born of clinical necessity observations of fetuses with congenital anomalies and neonates with irreversible end-organ damage led to the compelling rationale that correction in utero might arrest progression of disease or even reverse the pathophysiology and restore normal development. Surgery is a technology consisting of a physical intervention on tissues as a general rule, a procedure is considered surgical when it involves cutting of a patient's tissues. We were able to assemble a fetal surgery team with active participation of pediatric neurosurgery, maternal fetal medicine, pediatric surgery, obstetric anesthesia, pediatric cardiology, and pediatrics.
