Spina bifida is a congenital malformation characterized by a failure in neural tube closure. Unprotected fetal neural tissue at the spine level undergoes not only progressive neurodegeneration in spinal cord, but also the impairment in brain development, hindbrain herniation or Chiari II malformation probably due to pressure disturbances resulting from a continuous leakage of cerebrospinal fluid through the defect. The neurological consequences at birth are irreversible and sometimes devastating, including paraplegia, sphincter urinary and fecal incontinence, hydrocephalus, cranial nerve disturbances, respiratory problems and death due to spinal cord injury and brain maldevelopment.
