Summary
Decompressive craniectomy reduces mortality in malignant middle cerebral artery infarction but not in severe traumatic brain injury. It does not significantly improve the combined outcome of death or dependence for either condition.
Area of Science:
- Neurosurgery
- Critical Care Medicine
- Neurology
Background:
- Decompressive craniectomy is a neurosurgical procedure used for various neurocritical illnesses.
- Recent randomized controlled trials (RCTs) have investigated its effectiveness, necessitating an updated evidence synthesis.
Purpose of the Study:
- To conduct a meta-analysis synthesizing current evidence on the efficacy of decompressive craniectomy in neurocritical conditions.
- To evaluate the impact of decompressive craniectomy on mortality and functional outcomes.
Main Methods:
- A comprehensive literature search was performed across multiple databases (PubMed, EMBASE, Cochrane) and grey literature.
- Ten RCTs were included, with data extraction and quality assessment performed by two independent investigators.
- Primary outcomes included the composite of death or dependence and the risk of death.
Main Results:
- Decompressive craniectomy significantly reduced the risk of death in malignant middle cerebral artery infarction (MCAI) (RR 0.46, P<0.00001).
- No significant reduction in mortality was observed for severe traumatic brain injury (TBI) (RR 0.83, P=0.49).
- No significant difference in the composite outcome of death or dependence was found for either MCAI or TBI patients.
Conclusions:
- Decompressive craniectomy offers a significant survival benefit for patients with malignant MCAI.
- Current evidence does not support the routine use of decompressive craniectomy to improve functional outcomes or reduce death/dependence in severe TBI.
