A prospective study of early versus late craniectomy after traumatic brain injury
1First Affiliated Hospital, College of Medicine, Zhejiang University, Hangzhou City, Zhejiang Province, PR China.
Background:
Decompressive craniectomy is an important method for managing traumatic brain injury (TBI). At present, controversies about this procedure exist, especially about the optimum operative time for patients with TBI.
Methods:
A prospective study was performed at the First Affiliated Hospital, College of Medicine, Zhejiang University. From January 2008 to December 2009, 25 patients who underwent early decompressive craniectomy were included in the study group, and 19 patients who underwent "late" decompressive craniectomy as a second-tier therapy for intracranial hypertension were included as a comparison group.
Results:
The 30-day mortality after the operation was 16% in the study group. The overall mortality rate was 20% at the 6-month follow-up. A total of 52% of the patients (13 patients) had good outcomes, and 7 patients remained in a severely disabled or vegetative state. In the comparison group, 4 patients died, and 12 had good outcomes at the 6-month follow-up. The remaining 3 patients had poor outcomes. The study group was well matched with the comparison group. However, the outcomes in the study group were not better than those in the comparison group, as evaluated by the 6-month GOS score.
Conclusion:
Early decompressive craniectomy as a first-tier therapy for intracranial hypertension did not improve patient outcome when compared with "late" decompressive craniectomy for managing TBI.
