The location of the shunt is determined by the neurosurgeon based on the type and location of the blockage causing hydrocephalus. All brain ventricles are candidates for shunting. The catheter is most commonly placed in the abdomen but other locations include the heart and lungs. [10] Shunts can often be named after the route used by the ...
It also has its therapeutic value as the operation provides structure to the skull and protection to the brain from physical damage. [1] [6] The surgery restores regular cerebrospinal fluid (CSF) and cerebral blood flow dynamics, along with normal intracranial pressure. [1] [3] Cranioplasty may improve neurological function in some individuals.
Neurosurgery or neurological surgery, known in common parlance as brain surgery, is the medical specialty that focuses on the surgical treatment or rehabilitation of disorders which affect any portion of the nervous system including the brain, spinal cord, peripheral nervous system, and cerebrovascular system.

Hemispherectomy is a surgery that is performed by a neurosurgeon where an unhealthy hemisphere of the brain is disconnected or removed. There are two types of hemispherectomy. Functional hemispherectomy refers to when the diseased brain is simply disconnected so that it can no longer send signals to the rest of the brain and body.
Risk-benefit analyses have shown beyond any doubt that surgery for NPH is far better than conservative treatment or the natural course. [22] VP shunt is less likely to be recommended in those who have severe dementia at time of NPH diagnosis, regardless of findings found on MRI or CT. [10] [28] Gait symptoms improve in ≥ 85% patients.
Nearly all implants require open brain surgery, but, in 2019, a company called Synchron was able to successfully implant a brain–computer interface via the blood vessels. There have been a number of advances in technological spinal cord injury treatment, including the use of implants that provided a “digital bridge” between the brain and ...
Each of the types of shunts listed above can be composed of a tube or catheter and various types of valves, although they can just be composed of the tubing or catheter. Below is a list of valves that are used in lumbar–peritoneal shunts (LP shunts) and Cerebral shunts (for a more detailed list of the types of valves see type of valves): Delta
Decompressive craniectomy (crani-+ -ectomy) is a neurosurgical procedure in which part of the skull is removed to allow a swelling or herniating brain room to expand without being squeezed. It is performed on victims of traumatic brain injury, stroke, Chiari malformation, and other conditions associated with raised intracranial pressure. Use of ...
