Decompressive Craniectomyis done with people having abrain injury. Brain surgery is for people, who want to take off the pressure on thebrain or for people who will die without intervening. Often we have observed that injury brings swelling with it. The brain is a body part encompassed in bones, so there is no space available for swelling of thebrain. If a person gets swelling in thebrain, the pressure on it increases, and blood flow decreases this leads that person to death. In such cases, we need to minimize the pressure, and for that, a hole is made in theskull that creates for thebrain to swell.
This removal of theskull to decrease pressure on thebrain is called Decompressive Craniectomy. It is generally done in thecase of severe brain injuries when swelling is not improving by medication or through ventriculostomy. It is often usedin case of people having intracranial hypertension whose post results were traumatic brain swelling. People having large intracranial pressure are always recommend this solution first.
It involves removing of bone flap or intracranial mass lesions. It also reduces mortality, functional recovery and duration of stay in intensive care unit. There is an age limit in Decompressive Craniectomy, the person’s age limit should be 50 years. The most important drawback of Decompression Craniectomyis the increased riskto brain injury. For it, minimum two surgeries are performed:Removal of bone flap and repairing the defect, that is cranioplasty.
There should be right timing and improved patient selection for better results. The biggest complications faced during Decompressive Craniectomy are sinking of skin flap, hydrocephalus, contralateral subdural effusions and infections
