Comparative Analysis of Decompressive Craniectomy in Pediatric Severe TBI
Overview
This retrospective study evaluated 48 pediatric patients (≤16 years) with severe traumatic brain injury (TBI) treated between 2008 and 2018, comparing clinical presentation, treatment, and outcomes to a historic cohort from 1996 to 2007. Findings highlight differences in surgical approaches, monitoring, and outcomes in a specialized pediatric intensive care setting versus a historic adult neurocritical care environment.
Background
Severe traumatic brain injury (TBI) in children, defined by a Glasgow Coma Scale (GCS) ≤ 8, remains a critical cause of morbidity and mortality despite decreasing incidence from traffic accidents. Pediatric TBI differs pathophysiologically from adult TBI, with more diffuse brain swelling and better potential for recovery. Decompressive craniectomy (DC) is a recognized rescue therapy for refractory elevated intracranial pressure (ICP) or diffuse mass lesions, but data on pediatric outcomes remain limited. This study aims to provide comprehensive data on treatment and outcomes in a specialized pediatric setting compared to historical data.

Key Findings
Severe pediatric TBI patients treated in a specialized pediatric ICU showed tailored surgical and medical management including early ICP monitoring and use of DC as rescue therapy.
Diffuse brain swelling was more frequent in pediatric patients, influencing the decision for decompressive craniectomy.
Compared to the historic cohort treated in an adult neurocritical care environment, the recent cohort benefited from specialized pediatric care and updated Brain Trauma Foundation guidelines.
Outcomes were assessed using Glasgow Outcome Scale (GOS) at discharge and up to 36 months, with attention to posttraumatic hydrocephalus and surgical complications.
Secondary DC was performed for refractory ICP elevation or early uncontrollable ICP rise, following a defined treatment algorithm.
Clinical Implications
Specialized pediatric intensive care and neurosurgical management, including early ICP monitoring and timely decompressive craniectomy, are critical in managing severe pediatric TBI. Adherence to updated guidelines and treatment algorithms may improve long-term neurological outcomes and reduce complications. Clinicians should consider the distinct pathophysiology of pediatric TBI when planning interventions.
Conclusion
This study underscores the importance of specialized pediatric care in the management of severe TBI, demonstrating differences in treatment approaches and outcomes compared to historic adult-centered care. Continued research and multicenter data are needed to optimize protocols and improve recovery in this vulnerable population.
