NCT03090633

Brief Summary

The purpose of this investigation is to evaluate maternal and fetal outcomes following fetoscopic repair of fetal spina bifida at the Johns Hopkins Hospital. The hypothesis of this study is that fetoscopic spina bifida repair is feasible and has the same effectiveness as open repair of fetal spina bifida, but with the benefit of significantly lower maternal and fetal complication rates. The fetal benefit of the procedure will be the prenatal repair of spina bifida. The maternal benefit of fetoscopic spina bifida repair will be the avoidance of a large uterine incision. This type of incision increases the risk of uterine rupture and requires that all future deliveries are by cesarean section. The use of the minimally invasive fetoscopic surgical technique may also lower the risk of preterm premature rupture of membranes and preterm birth compared to open fetal surgery. Finally, successful fetoscopic spina bifida repair also makes vaginal delivery possible.
