[Prenatal myelomeningocele repair - a chance to improve the quality of life].

: Spina bifida (myelomeningocele) is the most prevalent developmental defect of the nervous system. In different regions of the world it affects from 0.3 to 5 per 1000 of living neonates. It is known that the defect develops during the early fetal life however no explicit cause has been found yet. Recently it has been accepted that one of the major factors contributing to spina bifida is deficiency of folic acid in the mother's body before and during pregnancy. The first attempts to cure myelomeningocele were taken in ancient times. More extensive knowledge of aetiology and effects of spina bifida and development of new surgical techniques allowed for management not only of the defect itself but also the consequent complications. Prenatal spina bifida repair has been performed in the USA for 20 years now while European surgeons (Poland and Switzerland) have operated myelomeningocele for 12 years. Comparative analysis carried out to evaluate the patients operated for spina bifida prenatally and postnatally pointed that those after fetal repair demand the use of ventriculoperitoneal shunt for hydrocephalus twice less frequently. Thanks to shortened exposure of the spinal cord and the spinal nerves to the toxic effect of amniotic fluid and reduced exposure to mechanical injuries, prenatal myelomeningocele repair offers better opportunities to improve motor, urinary and alimentary functions, contributing then statistically to higher quality of lives of children with spina bifida.
