NTDs are one of the most common birth defects, affecting over 300,000 births each year worldwide. [2] For example, spina bifida affects approximately 1,500 births annually in the United States, or about 3.5 in every 10,000 (0.035% of US births), [1] [3] which has decreased from around 5 per 10,000 (0.05% of US births) since folate fortification ...
Risks of fetal surgery, specifically prenatal spina bifida repair, include premature rupture of membranes, uterine rupture in future pregnancies, premature birth and intraspinal inclusion cysts or a tethered cord in the fetus or newborn baby. [4] Open fetal surgery has proven to be reasonably safe for the mother. [3]
