What is Chiari 1malformation?
Chiari malformation type 1 occurs when the section of the skull containing a part of the brain (cerebellum) is too small or is deformed, thus putting pressure on and crowding the brain. The lower part of the cerebellum (tonsils) is displaced into the upper spinal canal.
What is a Craniocervical decompression?
What is a craniocervical decompression? A cranio-cervical decompression is an operation involving the back of the head and top or the neck, i.e., the cranio-cervical junction, where the neurosurgeon creates extra room for the bottom part of the brainstem and top part of the spinal cord.
What is idiopathic syrinx?
Disease definition. Idiopathic syringomyelia is a rare, non-syndromic central nervous system malformation characterized by a longitudinally oriented fluid-filled cavity inside the spinal cord parenchyma or the central canal, without any readily identifiable cause.
Can syringomyelia cause breathing problems?
Complications of syringomyelia In some cases of syringomyelia, the cyst grows into the brain stem and interferes with vital functions such as breathing and heartbeat. This complication is called syringobulbia. Some of the symptoms of syringobulbia may include: swallowing difficulties.
Is Chiari decompression considered brain surgery?
The main operation for Chiari malformation is called decompression surgery. Under general anaesthetic a cut is made at the back of your head and the surgeon removes a small piece of bone from the base of your skull. They may also remove a small piece of bone from the top of your spine.
What is the difference between hydromyelia and syringomyelia?
Syringomyelia is associated with an intrinsic pathogeny of abnormal CSF circulation in the SAS. Hydromyelia is a non-evolutive thin cavity located at the central canal and can be assimilated to a persistent central canal. For the latter, there is no need of treatment or even strict surveillance.
What is the difference between syringomyelia and hydromyelia?
Syringomyelia is the development of a fluid-filled cavity or syrinx within the spinal cord. Hydromyelia is a dilatation of the central canal by cerebrospinal fluid (CSF) and may be included within the definition of syringomyelia.
Is Hydromyelia serious?
Hydromyelia develops when a fluid-filled cyst forms in your brain’s fourth ventricle. Some children experience no symptoms or mild symptoms that don’t need treatment. Moderate to severe symptoms can impact daily life but may improve with a shunt. Some children need more than one shunting procedure.
