Ped Neurosurgeons Come Back with Control

Brigitte Matsuoka — Mon, 26 Oct 2009 16:36:40 +0000

Pediatric Neurological Surgery Center doctors Neil Feldstein, MD, Director, and Richard Anderson, MD, came back from a recent conference with potentially exciting news for some of our pediatric patients. There may be a new way to help people whose nerve damage has cost them control over their bladders.

People with spinal cord injury and spina bifida suffer urinary dysfunction that can cause not just inconvenience, but danger. They must use a catheter to urinate and are at risk for multiple urinary tract infections, even lasting kidney damage. At the First International Symposium on Bladder Neuro-restoration and Nerve Rerouting, our doctors learned about new surgeries to help restore bladder control.

One of the newest methods highlighted at the symposium, which was sponsored by Beaumont Hospital in Royal Oak, MI, is called nerve rerouting. Surgeons switch around nerves within the spinal cord, ultimately improving urinary function. Doctors Feldstein and Anderson are investigating whether our pediatric spina bifida patients could benefit from this procedure.Pe

Spina Bifida

Spina bifida is one of the most common birth defects compatible with life. Technically it means an open spinal column, but has come to specifically relate to those instances when not only is the spinal column open, but the spinal cord is incompletely formed and is exposed to the air, the aperta form. The much more common form is the closed or occulta form which is probably of little significance and seen widely in the population. The spinal cord forms in the first few weeks of gestation. In addition to genetic and environmental associations, it is felt that folate deficiency may be an underlying factor in its development. Besides the failure of the spinal cord to form and close properly, other defects can occur in the development of the nervous system. These include hydrocephalus, syringohydromyelia and Chiari malformations. In addition there are poten tial disturbances with the bowel and bladder function, both extremity and spine related problems and respiratory and swallowing difficulties. These problems are due wholly or in part to the disturbance in the nervous system.

The diagnosis can of ten be made on the basis of a high resolution ultrasound or elevation of maternal alpha fetal protein levels. Other times it is not recognized until birth. It is widely accepted that most children born with spina bifida should be aggressively treated both medically and surgically. Recommendations are for early closure of the back and spinal cord as well as management of hydrocephalus if indicated. The important thing to realize is that this operation is designed specifically to prevent infection or ongoing trauma to the exposed spinal cord and not to return function which is not present at birth. This is not an insignificant distinction. Hydrocephalus is usually present in @80-90% of children with spina bifida and should b e treated when determined, usually before discharge from the hospital.

As many different parts of the body and nervous system are potentially involved, the child will need to see numerous physicians and therapists for follow up. In addition to physical therapy and early intervention, the child may need treatment for incontinence as well as bracing for the legs or spine. In many areas of the country this follow up is provided through multidisciplinary spina bifida clinics. These clinics are staff ed by the various physicians and therapists whose specialties pertain to the treatment of spina bifida.

Another entity which is common in children with spina bifida is known as Chiari Malformation. There are different forms of Chiari malformations, but most are either Type I or Type II. To simplify things, all children with spina bifida have some degree of Type II malformation. The thing to realize, is that while it is present radiographically it may not be causing the child any symptoms and therefor does not necessarily need to be treated. Often a parent will call up anxiously when they read a routine MRI report only to find that some strange malformation that they never heard of is present in their child. The truth is that it has always been present but never commented on. The type of symptoms that can occur with Chiari malformations include repeated aspirations, apnea, neck pains, and complaints of weakness or funny sensations in the arms. Usually, surgic al treatment for Chiari malformations is reserved for those children with clear evidence of progressive symptoms not for findings on an MRI.

Of course the most important question is “will my child be normal?” The answer is a bit compli cated but in general most children are competitive both physically and mentally. The majority will be of normal or above normal intelligence. The majority will be ambulatory without assistance but may require significant bracing or wheelchairs. The majori ty will be incontinent but socially continent with the use of catheterization.

Pediatric Neurosurgery Center

The Pediatric Neurosurgery Center specializes in the evaluation and treatment of children with a range of neurosurgical disorders, such as brain tumors, spasticity, movement disorders, intractable epilepsy, hydrocephalus, craniosynostosis, head injuries, and spina bifida, as well as other cranial malformations and spinal deformities. Our surgeons work as part of a multidisciplinary team of pediatric practitioners, offering a range of specialized expertise that can only be found at a hospital dedicated solely to children.

The Pediatric Neurosurgery Center is internationally recognized for its outstanding care of infants, children, and young adults with diseases or injuries to the brain or spinal cord. Members of our team are actively involved in clinical research on pediatric brain tumors, supported by the Pediatric Brain Tumor Fund. Studies consistently demonstrate that experienced surgeons at neuroscience centers of excellence achieve the best possible patient outcomes.
