what is the medical term for burr hole in brain
What are burr holes? Burr holes are small holes that a neurosurgeon makes in the skull. Burr holes are used to help relieve pressure on the brain when fluid, such as blood, builds up and starts to compress brain tissue. A layer of thin tissues called meninges surround and help protect the brain. These meninges contain blood vessels that carry blood to and from the brain.
