'''Decompressive Craniectomy''' 

'''Decompressive Craniectomy''' (''de-com-press-ive cran-ee-ec-to-my'') is a surgical procedure performed to relieve [[intracranial pressure]] in the skull. This procedure involves the removal of a part of the skull, allowing the brain to swell without being compressed. 

==Etymology==
The term "Decompressive Craniectomy" is derived from the Latin words "decompressio" meaning "pressure relief", "cranium" meaning "skull", and "ectomy" meaning "removal". 

==Procedure==
During a Decompressive Craniectomy, a large section of the skull is removed. The [[dura mater]], a tough membrane that covers the brain, is then opened to allow the brain tissue to expand freely. This procedure is typically performed on patients suffering from severe [[brain injuries]] or [[stroke]], where swelling of the brain (known as [[cerebral edema]]) can lead to life-threatening increases in intracranial pressure.

==Risks and Complications==
Like any surgical procedure, Decompressive Craniectomy carries certain risks and potential complications. These may include infection, bleeding, and damage to the brain tissue. There is also the risk of [[hydrocephalus]], a condition where an excess of cerebrospinal fluid accumulates in the brain.

==Related Terms==
* [[Craniotomy]]: A surgical operation in which a bone flap is temporarily removed from the skull to access the brain.
* [[Hemicraniectomy]]: A type of decompressive craniectomy where half of the skull is removed.
* [[Intracranial pressure]]: The pressure inside the skull and thus in the brain tissue and cerebrospinal fluid.
* [[Cerebral edema]]: Swelling in the brain caused by the presence of excessive fluid.
