Summary
Early decompressive craniectomy is crucial for severe traumatic brain injury (TBI). A drop in cerebral perfusion pressure (CPP) below 70 mmHg after initial surgery independently predicts the need for secondary surgery and poorer outcomes.
Area of Science:
- Neurosurgery
- Traumatology
- Neurocritical Care
Context:
- Traumatic brain injury (TBI) management often requires early decompressive craniectomy for moderate to severe cases with herniation risk.
- The role of secondary decompressive craniectomy after initial surgery for TBI remains debated due to limited outcome data.
- This study investigates the incidence, decision criteria, and outcomes of secondary decompressive craniectomy in isolated TBI patients.
Purpose:
- To determine the incidence of increasing brain edema following isolated TBI and primary craniectomy.
- To identify predictive criteria for secondary decompressive trepanation.
- To evaluate neurological outcomes using the Glasgow Outcome Score (GOS) at 6 months post-discharge.
Summary:
- Of 131 isolated TBI patients undergoing primary surgery, 11 required secondary decompressive craniectomy.
- Secondary craniectomy patients experienced delayed admission and more frequent prehospital otorrhagia.
- Decreased maximal cerebral perfusion pressure (CPP) post-primary operation independently predicted the need for secondary surgery and unfavorable GOS.
Impact:
- Prehospital hypotension and otorrhagia negatively impact mortality and morbidity in TBI patients.
- Early management of hypotension and rapid transport to neurotrauma centers are critical.
- Maximal CPP below 70 mmHg during ICU monitoring is a key indicator for potential operative revision and predicts poor long-term neurological outcomes.
