INTRODUCTION: The purpose of this study was to assess the role of decompressive craniectomy (DC) inpatients with post-traumatic intractable intracranial hypertension (ICH) in the absence of an evacuable intracerebral haemorrhage. METHODS: Retrospective study at LAC+USC Medical Centre including patients who underwent DC for post-traumatic malignant brain swelling or ICH without space occupying haemorrhage, during the period 01/2004 to 12/2008. The analysis included the effect of DC on intracranial pressure (ICP) and timing of DC on functional outcomes and survival. RESULTS: Of 106 patients who underwent DC, 43 patients met inclusion criteria. Of those, 34 were operated within the first 24 h from admission. DC decreased the ICP significantly from 37.8 ± 12.1 mmHg to 12.7 ± 8.2 mmHg in survivors and from 52.8 ± 13.0 to 32.0 ± 17.3 mmHg in non-survivors. Overall 25.6%died (11 of 43), and 32.5% (14 of 43) remained in vegetative state or were severely disabled. Favourable outcome (Glasgow Outcome Scale 4 and 5) was observed in 41.9% (18 of 43). No tendency towards either increased or decreased incidence in favourable outcome was found relative to the time from admission to DC.Six of the 18 patients (33.3%) with favourable outcome were operated on within the first 6 h. CONCLUSIONS: DC lowers ICP and raises CPP to high normal levels in survivors compared to non-survivors.The timing of DC showed no clear trend, for either good neurological outcome or death. Overall, the survival rate of 74.4% is promising and 41.9% had favourable neurological outcome. 2010 Elsevier Ltd. All rights reserved.
