Descemet membrane endothelial keratoplasty (DMEK) is a method of corneal transplantation that involves the removal of a thin sheet of tissue from the posterior (innermost) side of a person's cornea to replace it with the two posterior (innermost) layers of corneal tissue from a donor's eyeball.
At this time more blood is drained to reduce residual blood pressure if surgery on a cerebral aneurysm is to be performed to help create a bloodless surgical field. [41] After surgery is completed during the period of cold circulatory arrest, these steps are reversed. The brain and heart naturally resume activity as warming proceeds.
The bleed can be very small without any significant effect on surrounding brain or large hemorrhage that exerts mass effect on adjacent brain. Follow up CT scan is recommended. Those with extension of bleed into the ventricular system , expansion of bleeding, or increasing cerebral oedema on CT scan gives poorer prognosis.
The procedure is also used in epilepsy surgery to remove the parts of the brain that are causing epilepsy. Craniotomy is distinguished from craniectomy (in which the skull flap is not immediately replaced, allowing the brain to swell, thus reducing intracranial pressure) and from trepanation , the creation of a burr hole through the cranium ...

The Game of Thrones actor revealed in a personal essay published in The New Yorker that she had survived two brain aneurysms during the early years of making the fantasy show.
A procedure to place an external ventricular drain may be used to treat hydrocephalus or increased intracranial pressure, however, the use of corticosteroids is frequently avoided. [1] Sometimes surgery to directly remove the blood can be therapeutic. [1] Cerebral bleeding affects about 2.5 per 10,000 people each year. [2]
