Outcomes of Pediatric Traumatic Brain Injury Patients Presenting with or Developing Cerebral Herniation

Abstract

Traumatic brain injury (TBI) is the leading cause of mortality and morbidity in children. Previous studies evaluated outcomes of adult patients; however, few assessed outcomes of pediatric TBI patients presenting with herniation. This study investigated outcome data in pediatric patients presenting with TBI and cerebral herniation and the interventional strategies used for each patient in a rural community. A dual-institution retrospective review of 50 pediatric patients presenting with TBI and cerebral herniation from January 2011 to December 2020 was conducted. Mechanism of injury; herniation based on radiology findings; admission, presurgery, and postsurgery Glasgow Coma Scale scores; intracranial pressure values; discharge Glasgow Outcome Scale scores; length of stay; intensive care unit length of stay; procedures performed; and 30-day mortality/morbidity were collected for each patient. Although a nonsurgical approach led to better outcomes (29.4% vs. 48.4% mortality rate), early intervention with decompressive craniectomy improved morbidity in patients with severe TBI and cerebral herniation. Male patients presenting with TBI complicated by herniation were more likely to have a fatal outcome compared with female patients (51.6% vs. 26.3%). Behavior and age at injury may play a role in these differences. TBI remains a serious concern in the pediatric population with no clear guidelines on the optimal treatment. This study highlights the advantage of integrating more aggressive surgical intervention, such as decompressive craniectomy, in rural communities earlier in the hospital course. Future studies should explore additional factors that could contribute to outcomes in this patient population.
