Subdural Hematoma

A subdural hematoma (SDH) is a common neurosurgical disorder that often requires surgical intervention. It is a type of intracranial hemorrhage that occurs beneath the dura (essentially, a collection of blood over the surface of the brain) and may be associated with other brain injuries.

What causes SDH?

SDH's are most often caused by sudden impacts shaking the skull. Sudden shifting of the brain within the skull (rattling around like a tennis ball in a can) can tear the small blood vessels that bridge between the skull and brain.
