Summary
Vascularized galea pericranium grafts improved outcomes for traumatic brain injury patients undergoing decompressive craniectomy compared to synthetic grafts. This approach offers better functional recovery at 6 months and 1 year post-surgery.
Area of Science:
- Neurosurgery
- Trauma Surgery
- Regenerative Medicine
Background:
- Optimal dural substitute for primary decompressive craniectomy (PDC) in traumatic brain injury (TBI) remains debated.
- Comparing vascularized galea pericranium (VP) with synthetic dural substitutes (SR) is crucial for improving patient outcomes.
Purpose of the Study:
- To compare the clinical outcomes of PDC using anterior-based vascularized galea pericranium versus synthetic dural substitutes.
- To evaluate the efficacy and safety of different dural grafting techniques in TBI patients.
Main Methods:
- Retrospective analysis of 97 TBI patients undergoing PDC from April 2015 to February 2022.
- Propensity matching created 28 pairs (56 patients) comparing VP grafts (n=60) to SR grafts (n=37).
- Primary outcome: extended Glasgow Outcome Scale (GOS-E) at 6 months; secondary outcomes: complications, surgical time, ICU/hospital stay, mortality, GOS-E at 1 year.
Main Results:
- VP group showed significantly better GOS-E scores at 6 months (P=.011) and 1 year (P=.026) compared to SR group.
- No significant differences in mortality, ICU/hospital stay, surgical time, or overall complications (infections, hemorrhagic, hydrodynamic) between groups.
- Brain abscess occurred exclusively in the SR group (P=.327).
Conclusions:
- Anterior-based vascularized galea pericranial grafts are associated with superior clinical outcomes in TBI patients undergoing PDC.
- VP grafts offer a promising alternative to synthetic dural substitutes for improved functional recovery post-TBI.
- Further research may solidify VP grafts as a preferred method for duroplasty in TBI management.
