Multiple subpial transection
Multiple Subpial Transection (pronunciation: mul-ti-ple sub-pi-al tran-sec-tion) is a surgical procedure used to treat epilepsy when the area of the brain where seizures originate is too vital to be removed. The procedure involves making a series of shallow cuts (transections) in the brain tissue to interrupt the movement of seizure impulses but leaves the abilities of the brain intact.
Etymology
The term originates from the Latin words multiplus meaning "multiple", sub meaning "under", pia meaning "tender", and sectio meaning "cutting".
Procedure
During a Multiple Subpial Transection, the surgeon makes a series of cuts in the brain tissue. These cuts are designed to interrupt the pathways used by seizures to spread through the brain. However, the cuts do not go deep enough to disrupt the normal functions of the brain. This procedure is often used when the area of the brain responsible for seizures is also responsible for important functions such as language, motor function, or sensory processing.
