Ferri’s Clinical Advisor Shunt complications in the first postoperative year in children with meningomyelocele. The Bayley scores were ranked across all infants, with fetal, neonatal, or infant deaths being assigned the lowest rank. A group sequential method was used to characterize the rate at which the type I error was spent; the chosen spending function was the Lan—DeMets characterization of the O’Brien—Fleming boundary.
However, one fifth of those in the prenatal-surgery group had evidence of the respiratory distress syndrome, which was probably caused by prematurity. Journal of Pediatric Urology. For all secondary outcomes, a nominal P value of less than 0. Escrito por el personal de Mayo Clinic. Open neural tube defects: Two perinatal deaths occurred in each group.
Solicite una Consulta en Mayo Clinic. The assessment of the hysterotomy site at the time of delivery revealed thinning or an area of dehiscence in more than one third of the women.
GENETICA Y SEXOLOGIA INTEGRAL: CIRUGIA PRENATAL DE MIELOMENINGOCELE
The same procedure was separately conducted for the calculated difference between functional and anatomical level. For cirugiq up to 30 months, the report is based on the findings in women who underwent randomization before December 1, Endoscopic third ventriculostomy for the treatment of hydrocephalus in a pediatric population with myelomeningocele.
There were no significant between-group differences in the rates of other complications of prematurity. For example, a body-mass index of 35 or more was an exclusion criterion for safety reasons, even though obesity is common among women carrying a fetus with myelomeningocele. In the prenatal-surgery group, an intrauterine fetal mileomeningocele was diagnosed at 26 weeks a stillbirthand a neonatal death due to prematurity was diagnosed dr 23 weeks; both deaths occurred on the fifth postoperative day.
All surgeons used a stapling device with absorbable staples for uterine entry.
Centers for Disease Control and Prevention. Inclusion criteria were a singleton pregnancy, myelomeningocele with the upper boundary located between T1 and S1, evidence of hindbrain herniation, a gestational age of Damage to the spinal cord and peripheral nerves usually is evident at birth and is irreversible despite early postnatal surgical repair.
Discussion As compared with postnatal surgery, prenatal surgery for myelomeningocele that was performed before 26 weeks of gestation decreased the risk of death or need for shunting by the age of 12 months and also improved scores on a composite measure of mental and motor function, with adjustment for lesion level, at 30 months of age.
Major exclusion criteria were a fetal anomaly unrelated to myelomeningocele, severe kyphosis, risk of preterm birth including short cervix and previous preterm birthplacental abruption, a body-mass index the weight in kilograms divided by the square of the height in meters of 35 or more, and contraindication to surgery, including previous hysterotomy in the active uterine segment.

Mayo Clinic Health Letter. Previous cohort studies have suggested improved outcomes with prenatal surgery for myelomeningocele. Potential benefits of prenatal surgery must be balanced against the risks of prematurity and maternal morbidity. Analyses were performed according to the intention-to-treat principle. The trial was approved by the institutional review board at each center.
Infant secondary outcomes were radiographic appearance of components of the Chiari II malformation, as evaluated by independent radiologists; the mielomenijgocele to the first shunt placement or meeting the criteria for such placement ; locomotion; the Psychomotor Development Index of the Bayley Scales; scores on the Peabody Developmental Motor Scales; the degree of functional impairment on the basis of physical examination; and the degree of disability, as measured by the WeeFIM Functional Independence Measure for Children instrument.
In the postnatal-surgery group, seven women chose not to return to the clinical center for delivery, and four were unable to return because of preterm labor or other complications.
Prenatal surgery also improved several secondary outcomes, including the degree of hindbrain herniation associated with the Chiari II malformation, motor function as measured by the difference between the neuromotor function level and anatomical lesion leveland the likelihood of being able to walk independently, as compared with postnatal surgery.
The median survival time in open spina bifida. In the case of infants with low lumbar and sacral lesions, in whom less impairment in lower-limb function may be predicted, the normalization of hindbrain position and the minimization of the need for postnatal placement of a cerebrospinal fluid shunt may be the primary indication for surgery.
Mielomenintocele in the lower limbs may be lost, and hindbrain herniation and hydrocephalus may worsen during fetal gestation. Pregnancy complications were more common among women in the prenatal-surgery group Table 2Table 2 Maternal and Fetal or Neonatal Outcomes.
This malformation is also associated with hydrocephalus and developmental brain abnormalities. In our study, prenatal surgery for milomeningocele reduced the need for shunting and improved motor outcomes at 30 months, but the early intervention was associated with both maternal and fetal morbidity. Alpha-fetoprotein AFPsingle marker screen, maternal, serum. Trends in the postfortification ciruhia of spina bifida and anencephaly in the United States. Although the prenatal-surgery group had better outcomes than the postnatal-surgery group, not all infants benefited from the early intervention, and some had a poor neuromotor outcome.

We compared continuous variables using the Wilcoxon test and categorical variables using the chi-square test, Fisher’s exact test, or the Cochran—Armitage test for trend. Orthopedic issues in myelomeningocele spina bifida. Surgical revisions are common to address shunt failure or infection.
Finally, for the children in this study, continued follow-up is needed to assess whether the early benefits are durable and to evaluate the effect of prenatal intervention on bowel and bladder continence, sexual function, and mental capacity. The results of this trial should not be generalized to patients who undergo procedures at less experienced centers or who do not meet the eligibility criteria. For the first primary end point, we report the The study protocol, including the statistical analysis plan and full inclusion and exclusion criteria, is available with the full text of this article at NEJM.
The month examination included radiography of the spine to determine the anatomical level of the lesion and magnetic resonance imaging of the head and spine. Current selection criteria and perioperative therapy used for fetal myelomeningocele surgery.
Mayo Clinic, Rochester, Minn. Because this trial was unmasked and criteria for shunt placement vary widely, an independent committee of neurosurgeons, who were unaware of study-group assignments, reviewed the clinical and radiologic data for each child to determine whether criteria for shunt placement were cirugoa.
The severity of the neurologic disability in the lower limbs is correlated with the level of the injury to the spinal cord.
Shepard CL, et al. Primary Muelomeningocele Two primary outcomes were prespecified. Preterm labor leading to early delivery, placental abruption, and pulmonary edema associated with tocolytic therapy are well-known complications of prenatal surgery. Trained independent pediatricians and psychologists who were unaware of study-group assignments and who reported directly to the coordinating center conducted the testing.
