Prevalence of Contrast Extravasation and Embolization in Blunt Liver and Spleen Injuries at a Single Pediatric Trauma Center

jpedsurg.org

In 2019, the APSA guidelines for the management of solid organ injuries in children recommended limiting embolization to patients with evidence of ongoing hemorrhage. We sought to identify patients who presented to our institution with contrast extravasation (CE) on initial imaging, determine the proportion who required embolization, and describe their associated outcomes.

In brief

This study evaluates the prevalence of contrast extravasation on CT imaging in pediatric blunt liver and spleen injuries and examines how often these patients required angioembolization. The research aligns with 2019 APSA guidelines recommending selective embolization for active hemorrhage, providing outcome data to guide non-operative management decisions in pediatric trauma.

APSA 2019 guidelines recommend limiting embolization to pediatric patients with evidence of ongoing hemorrhage in solid organ injuries.
Contrast extravasation on initial CT does not always require embolization; selective management based on clinical status is appropriate.
Single-center data can help identify which pediatric liver/spleen injury patients with CE truly need intervention versus observation.
Outcomes analysis of CE patients helps refine embolization criteria and avoid unnecessary procedures in stable children.
Evidence-based protocols reduce overtreatment while maintaining safety in pediatric blunt abdominal trauma management.
