Decompressive craniectomy(DC)is a surgical method for managing highly elevated intracranial increased pressure(ICP)resulted from severe head trauma.This procedure is able to reduce the ICP rapidly and effectively.However,it may lead to kinds of secondary complications,which would cause patient’s severe neurological dysfunction or even death.In this paper,we reviewed the literatures about surgical complications secondary to DC,and tried to bring up suggestions on surgical techniques aiming to prevention and treatment of these complications.
