Balancing the short-term benefits and long-term outcomes of decompressive craniectomy for severe traumatic brain injury.

: The role of decompressive craniectomy in the management of neurological emergencies remains controversial. There is evidence available that it can reduce intracranial pressure, but it will not reverse the effects of the pathology that precipitated the neurological crisis, so there has always been concern that any reduction in mortality will result in an increase in the number of survivors with severe disability.: The results of recent randomised controlled trials investigating the efficacy of the procedure are analyzed in order to determine the degree to which the short-term goals of reducing mortality and the long-term goals of a good functional outcome are achieved.: Given the results of the trials, there needs to be a change in the clinical decision-making paradigm such that decompression is reserved for patients who develop intractable intracranial hypertension and who are thought unlikely to survive without surgical intervention. In these circumstances, a more patient-centered discussion is required regarding the possibility and acceptability or otherwise of survival with severely impaired neurocognitive function.
