One case report of delayed severe intracerebral and intraventricular hemorrhage after cranioplasty.

Aside from hyperperfusion and cerebral autoregulation dysfunction, traction injuries to the fragile vessels due to posttraumatic angiogenesis may also be one of the key factors of complications after cranioplasty.
