Does Chiari malformation cause hydrocephalus?

A Chiari malformation can also cause pressure on the brain and produce hydrocephalus (pressure due to excessive cerebrospinal fluid accumulation in the brain) and the spinal cord, potentially causing a wide variety of symptoms.

How does Arnold Chiari malformation cause hydrocephalus?

Causes of Chiari Malformations Due to genetic mutations or a maternal diet that lacked certain nutrients, the indented bony space at the base of the skull is abnormally small. As a result, pressure is placed on the cerebellum. This blocks the flow of the cerebrospinal fluid.

How long does it take to recover from Chiari malformation surgery?

Recovery from the actual surgery varies from 4 to 6 weeks, depending on your general health. After surgery, you can expect headache and neck pain from the incision that may last several weeks. You will be given neck exercises (download exercises) to do at home.

Can Chiari cause permanent damage?

As a child grows, the disorder worsens and can result in permanent damage to the nerves that control the muscles in the lower body and legs. Children who have a myelomeningocele have an increased risk of developing a tethered cord later in life.

Are there any complications associated with a Chiari?

There is much debate among neurosurgeons as to whether doing routine duraplasty as part of decompression outweighs the risks. Some argue that duraplasty increases the risk of complications, while others say that failure to perform duraplasty often results in inadequate decompression, reduced benefit, and the need for additional surgeries.

What happens to the pseudomeningocele after a Chiari?

A study at Vanderbilt University at 2013 showed that the development of a pseudomeningocele after decompression significantly reduced the benefit of decompression at one-year post-op on pain, disability and quality of life. [9] A smaller pseudomeningocele may re-absorb on its own.

What are the risks of CSF leak after duraplasty?

The risk of a CSF leak dramatically increases with the presence of untreated hydrocephalus [5], intracranial hypertension ( IH) [6], and connective tissue disorders, such as Ehlers-Danlos Syndrome. Nationwide statistics indicate that the risk of a CSF leak post-duraplasty is 10-15%.
