You've been told you're having a baby with Spina Bifida. What next?
What is Spina Bifida?
Spina Bifida is a condition that affects the spine and is usually apparent at birth. It is a type of neural tube defect (NTD).
Spina Bifida can happen anywhere along the spine if the neural tube does not close all the way. When the neural tube doesn’t close all the way, the backbone that protects the spinal cord doesn’t form and close as it should. This often results in damage to the spinal cord and nerves.
Spina Bifida might cause physical and intellectual disabilities that range from mild to severe. The severity depends on:
- The size and location of the opening in the spine.
- Whether part of the spinal cord and nerves are affected.
What causes Spina Bifida?
No one knows for certain what causes Spina Bifida. The role that genetics and the environment play in causing Spina Bifida needs to be studied further.
Spina bifida happens in the first few weeks of pregnancy, often before a woman knows she’s pregnant. Although folic acid is not a guarantee that a woman will have a healthy pregnancy, taking folic acid can help reduce a woman’s risk of having a pregnancy affected by Spina Bifida. Because half of all pregnancies in the United States are unplanned, it is important that all women who can become pregnant take 400 mcg of folic acid daily.
How is Spina Bifida diagnosed?
Yes. There are 3 tests, but, it is important to remember that no medical test is perfect and the results are not always 100 percent accurate. Spina Bifida can be detected in utero by one or more of the following:
- A blood test during the 16th to 18th weeks of pregnancy. This is called the alpha-fetoprotein (AFP screening test). This test is higher in about 75–80 % of women who have a fetus with Spina Bifida.
- An ultrasound of the fetus. This is also called a sonogram and can show signs of Spina Bifida such as the open spine.
- A test where a small amount of the fluid from the womb is taken through a thin needle. This is called maternal amniocentesis and can be used to look at protein levels.
What medical issues do people with SB encounter?
People with SB face a number of medical issues to deal with throughout their lives. SB lesions need to be closed within 72 hours after birth) to prevent infection and further damage to the spinal cord.
Hydrocephalus is an excessive amount of spinal fluid (CSF) collecting in the ventricles of the brain. It occurs in approximately 80% of people with SB. Sometimes it occurs before birth, but most often it happens after the back has been closed. Hydrocephalus is usually treated by surgery to place a hollow tube, called a ventriculoperitoneal (VP) shunt, that transfers the fluid from the head to an empty space in the abdomen to prevent brain damage. (Please see the SBA’s info sheet on hydrocephalus and shunts for more information).
Neurogenic bowel and bladder and are caused by damage to the nerves that control the function of the bladder and the bottom section
of bowel and anus. In recent years, treatments have been developed which allow individuals to achieve varying levels of functional continence. (Please see the SBA’s information sheet on urologic care and management for more information).
• SB issues are dependent on the spinal level of the SB lesion. Most children can walk (though usually with the aid of orthopedic bracing and often with assistive devices such as crutches). Some are full-time walkers, but many walk short distances and choose a wheelchair for long distances. It is generally only those with thoracic or high lumbar spinal lesions who end up using the wheelchair as their only method of mobility.
• Most people with SB have normal IQ scores, they may have learning difficulties; but these can often be addressed when parents and teachers understand the issues and work together.
Every individual with SB is affected differently, and it is impossible to predict a child’s outcome before or at birth. Outcomes have improved over the 50 years due to medical advancements. Also, cultural attitudes toward individuals with disabilities have also changed, resulting in improved services. While some individuals with SB have significant disabilities, others are less severely affected. Many attain advanced education and have careers and families of their own. They become doctors, teachers, artists, athletes, and parents. Spina Bida is only one part of their lives; it does not dene them.
After you find out you’re having a baby with SB, what are the next steps?
It is recommended that you meet with a pediatric neurosurgeon and/or SB clinic as soon as possible. You will also need to meet with a maternal-fetal specialist or perinatologist to closely follow your pregnancy. You may also meet other specialists who care these to learn as much as you can. After you have gathered enough information to understand the immediate and long-term implications of SB, consider the choices available to you—terminating the pregnancy, prenatal or postnatal surgery, or adoption—what matters is that
you make an informed choice about what works best for you and your family.
Prenatal or Postnatal surgery
For pregnancies diagnosed earlier than 25 weeks gestation, in-utero fetal surgery may be an option to close the baby’s back
before birth. There are potential risks and benefits of fetal surgery, and it is not appropriate for all women. For those who choose and qualify, an immediate referral must be made to a medical center where the where the operation is performed.
Babies with SB should be delivered at a medical center that specializes in SB so they can receive specialty care during and after birth. This gives you and the specialists every chance to prepare for the best outcome. After surgery, the baby will be monitored in the neonatal intensive care unit. The average length of stay is 2 weeks, but this varies based on the child’s needs. When the baby is discharged from the hospital, he or she will have periodic follow-up appointments with a pediatric neurosurgeon, orthopedist, urologist, and possibly other specialists. Appointments will be frequent in the first year, and usually less often as time passes.
