Outcomes of Decompressive Craniectomy in the Management of Traumatic Brain Injury: A Ten-Year Retrospective Analysis

Abstract

Objective: This study aimed to investigate factors associated with patient outcomes after decompressive craniectomy for severe traumatic brain injury (TBI) and to compare the authors’ findings with the existing literature. Methods: The authors conducted a retrospective analysis of 50 patients who underwent decompressive craniectomy for severe TBI between 2013 and 2023. Patient characteristics, including age, sex, Glasgow Coma Scale (GCS) score, Injury Severity Score (ISS), electrolyte imbalances, nosocomial infections, and hospital stay duration, were collected. Outcomes were assessed at 12 months postsurgery, and statistical analyses were performed to determine factors associated with favorable and unfavorable outcomes. Results: Younger age, higher GCS scores, and lower ISS were significantly associated with favorable outcomes. Electrolyte imbalances, particularly hyponatremia, and hyperkalemia, were linked to unfavorable outcomes. Nosocomial infections were significantly more common in patients with unfavorable outcomes. Longer hospital stays were also associated with worse outcomes. Conclusions: The authors’ findings highlight the importance of individualized patient management based on age, admission GCS score, ISS, electrolyte imbalances, nosocomial infections, and hospital stay duration to maximize the potential for favorable outcomes. These results contribute to the growing literature on decompressive craniectomy for TBI and provide valuable insights for clinicians in optimizing patient management.
