Motor vehicle accidents are the third leading cause of all cases resulting in traumatic brain injuries (TBI). Some brain injuries result in hematoma, which is a pooling of blood outside the blood vessels that clots and leads to tissue damage. When a hematoma occurs in the brain, it can cause damage to the brain, and may even lead to death. To prevent the dire consequences that can result from a brain hematoma, surgery may be required to release pressure on the brain.
