Tethered cord syndrome after myelomeningocoele repair

摘要

Although the incidence of neural tube defects has fallen appreciably in the past two decades, from 3.4/1000 live births and stillbirths in 1974 to 0.8/1000 in 1994, the decline seems to be levelling off. The reduction is partly attributable to the increased consumption of folic acid by expectant mothers and partly to improved detection of defects in utero, which has led to the termi- nation of approximately 50/100 of these pregnancies.
