When there is an intense blow to the head can it lead to bleeding?

Hello, I wonder if when there is a very intense blow to the head can lead to a hemorrhage? If so, in what situation will this surgery be? Can this surgery be life threatening to the patient? And in the case of a hemorrhage, there is blood clotting?
Expert answer:

Very strong blow to the head can cause hemorrhage yes. Surgery is necessary if it is a large bleeding (large is quite relative in this case). Any surgery offers risk, this type even more so. Hemorrhage or clot has almost the same meaning in this situation (clot is formed only if there is bleeding).
