Decompressive craniectomy in trauma: What you need to know

Area of Science:

• Neurosurgery
• Trauma Surgery
• Critical Care Medicine

Background:

• Decompressive craniectomy (DC) involves removing a skull section to relieve intracranial pressure.
• Primary DC is used for acute subdural hematomas with brain swelling.
• Recent trials compare DC with craniotomy and evaluate its role in intracranial hypertension.

Purpose of the Study:

• To review current evidence on the efficacy and indications of decompressive craniectomy.
• To compare outcomes of primary DC versus craniotomy for traumatic acute subdural hematoma.
• To assess the role of DC as a last-tier therapy for refractory intracranial hypertension.

Main Methods:

• Review of recent randomized controlled trials and multicenter trials.
• Comparison of outcomes between decompressive craniectomy and craniotomy groups.
• Analysis of DC's effectiveness in mild, moderate, and refractory intracranial hypertension.

Main Results:

• Primary DC showed similar 12-month outcomes to craniotomy for acute subdural hematoma, with more wound complications in the DC group.
• Early neuroprotective DC for mild/moderate intracranial hypertension did not improve outcomes compared to medical management.
• Secondary DC as last-tier therapy for refractory intracranial hypertension reduced mortality and improved patient outcomes.

Conclusions:

• Secondary DC is valuable for managing intracranial hypertension post-traumatic brain injury but is not universally effective.
• The decision for DC should be individualized based on patient-specific factors.
• Further high-quality trials are needed to define optimal indications and techniques for various types of DC.
