Open spina bifida is strongly associated with hydrocephalus. Although the baby may not have enlarged ventricles before birth, once the surgery to close the spina bifida lesion is carried out, the CSF may have nowhere to go. It accumulates in the ventricles, resulting in hydrocephalus.
What does spinal fluid on the brain mean?
Overview. Hydrocephalus is the buildup of fluid in the cavities (ventricles) deep within the brain. The excess fluid increases the size of the ventricles and puts pressure on the brain. Cerebrospinal fluid normally flows through the ventricles and bathes the brain and spinal column.
How long can you live with water on the brain?
The mortality rate for hydrocephalus and associated therapy ranges from 0 to 3%. This rate is highly dependent on the duration of follow-up care. The shunt event-free survival is approximately 70% at 12 months and is nearly half that at 10 years, post-operatively.
Does spina bifida cause brain damage?
Some babies with spina bifida have hydrocephalus (excess fluid on the brain), which can damage the brain and cause further problems. Many people with spina bifida and hydrocephalus will have normal intelligence, although some will have learning difficulties, such as: a short attention span. difficulty solving problems.
How serious is water on the brain?
Hydrocephalus can permanently damage the brain, causing problems with physical and mental development. If untreated, it is usually fatal. With treatment, many people lead normal lives with few limitations. Treatment usually involves surgery to insert a shunt.
What is the life expectancy of a person with spina bifida?
The prognosis for survival was strikingly poor in those with the most extensive neurological deficit. Only 17% (7/42) of those born with a high sensory level (above T11) survived to the mean age of 40 years, compared with 61% (23/38) of those with a low sensory level (below L3; p=0.001).
What does spina bifida do to the brain?
Many babies born with spina bifida get hydrocephalus (often called water on the brain). This means that there is extra fluid in and around the brain. The extra fluid can cause the spaces in the brain, called ventricles, to become too large and the head can swell.
How do they remove fluid from the brain?
A shunt is the surgical insertion of a drainage system. A catheter (a thin tube with a valve) is placed in the brain to drain away excess fluid from the brain into another part of the body, such as the abdomen, the chest cavity, or a chamber of the heart.
What are the health risks of spina bifida?
Health issues are different for each person with spina bifida. Open spina bifida (myelomeningocele)—in which the spinal cord is exposed—tends to cause more severe problems. 1 Many infants born with spina bifida get extra fluid in and around the brain, a condition called hydrocephalus, or water on the brain.
What part of the brain does open spina bifida affect?
The brains of most children with open spina bifida are positioned abnormally. The lower part of the brain rests farther down than normal, partially in the upper spinal canal. The cerebrospinal (pronounced suh-ree-broh-SPAHYN-l) fluid can get blocked and cause hydrocephalus.
Do people with spina bifida have hydrocephalus?
Approximately 90% of people born with spina bifida also have Hydrocephalus. Somewhere along the CSF pathways, the flow of cerebrospinal fluid has been obstructed.
Is the spinal cord tethered in open spina bifida?
Many people with open spina bifida have tethered spinal cords. Normally, the bottom of the spinal cord floats around freely in the spinal canal. A tethered spinal cord is attached to the spinal canal.
