What is radical brain surgery?
The operation known as hemispherectomy—where half the brain is removed—sounds too radical to ever consider, much less perform. In the last century, however, surgeons have performed it hundreds of times for disorders uncontrollable in any other way.
Can a person live with only half a brain?
“As remarkable as it is that there are individuals who can live with half a brain, sometimes a very small brain lesion — like a stroke or a traumatic brain injury or a tumor — can have devastating effects,” she noted.
What are common brain surgeries?
What are some types of brain surgery?
- Craniotomy.
- Biopsy.
- Deep brain stimulation (DBS).
- Neuroendoscopy.
- Posterior fossa decompression.
- Thrombectomy and cerebral aneurysm repair.
What is radical hemispherectomy?
A hemispherectomy is a radical surgical procedure where the diseased half of the brain is completely removed, partially removed and fully disconnected or just disconnected from the normal hemisphere. This is one of the most successful operations at stopping seizures in carefully selected patients.
Can you live without a piece of your brain?
Since it controls vital functions such as breathing, swallowing, digestion, eye movement and heartbeat, there can be no life without it. But the rest of the brain is obviously capable of some remarkable feats, with one part able to compensate for deficiencies in another.
How long can you live without a brain?
Trevor passed away last year after going his entire life without a brain. He suffered from a rare condition called hydranencephaly, whereby the cerebral hemispheres are replaced entirely with cerebrospinal fluid. People with hydranencephaly usually survive for up to 12 weeks, which made Trevor’s case so remarkable.
How long do you live after brain surgery?
The average survival time is 12-18 months – only 25% of glioblastoma patients survive more than one year, and only 5% of patients survive more than five years.
What are the risks of a hemispherectomy?
Most children have excellent long-term results following a hemispherectomy. Occasionally, however, some complications may occur: Early complications, which occur either while the operation is happening or immediately after it, include blood loss, electrolyte changes, hypothermia and aseptic meningitis.
What is the success rate of hemispherectomy?
The outcome reported in this study is in line with previous results. Across studies, seizure reduction rates after hemispherectomy have ranged between 50% and 92%, with very low mortality rates (4).
