How is a myelomeningocele repaired?
During surgery, the doctor makes an incision across the mother’s abdomen and opens the uterus. The neurosurgeon removes the myelomeningocele sac, if one is present, and repairs the spinal defect in layers before closing the skin to protect the spinal cord from exposure to amniotic fluid.
Can neural tube defects be fixed in utero?
Neural tube defects are usually diagnosed before the infant is born, through lab or imaging tests. There is no cure for neural tube defects. The nerve damage and loss of function that are present at birth are usually permanent.
When should myelomeningocele be repaired?
In most instances, myelodysplasia should be treated surgically as soon after birth as possible, irrespective of whether the meningocele has ruptured.
Can spina bifida be corrected in utero?
While there is no cure for spina bifida, repairing the spine in the womb can minimize the spinal defect. Prenatal surgery also lowers the risk for a shunt. For babies that have surgery after birth, 82 percent will require a shunt to be placed in the brain.
Can you do surgery on a baby in utero?
Fetal surgery is a procedure performed on an unborn baby (fetus) in the uterus (in utero) to help improve the long-term outcome of children with specific birth defects.
What is the primary reason for surgical repair of a myelomeningocele?
 The aim of surgical repair of MMC is to cover the exposed spinal cord and the nerve roots, to prevent CSF leaks, and to reduce the chances of central nervous system infection, which can occur due to defects created by surgery.
Can neural tube defects happen after 20 weeks?
Neural tube defects may be diagnosed during the ultrasound scan that is carried out around week 12 of the pregnancy or, more likely, during the anomaly scan that is carried out at around weeks 18 to 20.
What will be the advantages of in utero surgery for the correction of spina bifida?
Benefits of Fetal Surgery Babies who undergo fetal spina bifida surgery in the womb have much better neurological outcomes than those who are operated on after delivery. During surgery, a team of surgeons works together to interrupt the damage to the spinal cord and brain while it’s developing inside the womb.
How is spina bifida surgery done in utero?
Doctors make a one centimeter incision in the uterus and use a special stapler to secure blood flow. Then they fill the uterus with a solution. The fetus floats to the top of the uterus and the spina bifida is exposed. Now doctors can begin the repair.
Can myelomeningocele be cured?
How is it treated? Most cases of myelomeningocele are treated surgically with a repair soon after birth. In some cases, the repair is done while still in the womb prior to delivery. Children that have hydrocephalus will likely require surgery to decrease fluid on the brain (VP shunt).
What surgeries can be performed in utero?

How is surgery performed in utero?
In open fetal surgery, the mother is anesthetized, an incision is made in the lower abdomen to expose the uterus, the uterus is opened using a special stapling device to prevent bleeding, the surgical repair of the fetus is completed, the uterus followed by the maternal abdominal wall are closed, and the mother …
Why does a myelomeningocele require protection after birth?
In treating myelomeningocele and meningocele, the key priorities are to prevent infection from developing in the exposed nerves and spinal cord through the spinal defect, and to protect the exposed nerves and spinal cord from additional trauma.
What are 3 risk factors for developing a neural tube defect?
- Folate deficiency. Folate, the natural form of vitamin B-9, is important to the development of a healthy baby.
- Family history of neural tube defects.
- Some medications.
- Increased body temperature.
What week does neural tube close?
Week 6: The neural tube closes Just four weeks after conception, the neural tube along your baby’s back is closing. The baby’s brain and spinal cord will develop from the neural tube. The heart and other organs also are starting to form.

- First-Trimester Fetal Echocardiography Program.
- Ex-utero Intrapartum Treatment (EXIT)

What is a myelomeningocele fetal repair?
Myelomeningocele (Spina Bifida) Fetal Repair. Myelomeningocele, a type of “open spina bifida,” is the most serious form of the disease. In myelomeningocele, a portion of the baby’s spinal cord and surrounding nerves protrude through an opening in the spine into an exposed, flat disc or sac that is visible on the back.
What is myelomeningocele spina bifida surgery?
Myelomeningocele (Spina Bifida) Fetal Repair. Babies who are born with hydrocephalus usually need ventriculoperitoneal (VP) shunting, which involves surgically implanting a thin, hollow tube with a valve underneath the skin, behind the ear, that drains excess fluid from the brain into the belly or chest area.
How long does it take to recover from myelomeningocele surgery?
The neurosurgeon removes the myelomeningocele sac, if one is present, and repairs the spinal defect in layers before closing the skin to protect the spinal cord from exposure to amniotic fluid. After the procedure, the uterus and abdomen are closed. Patients recover in the hospital for four to five days.
What are the age restrictions for fetal surgery for myelomeningocele?
