BackgroundSplenic arterial embolization (SAE) is an effective intervention for the management of arterial hemorrhage asso-ciated with blunt splenic injury. However, its role and clinical outcomes in pediatric and adolescent patients are unclear. The aim of this study is to assess the role and the clinical outcomes of SAE for blunt splenic injuries in pediatric and adolescent trauma patients.MethodsA retrospective cohort study was performed in patients aged ≤17 years with blunt splenic injury transferred to a re-gional trauma center in a tertiary referral hospital between November 01, 2015, and September 30, 2020. The final study population consisted of 40 pediatric and adolescent patients with blunt splenic injuries. The patient demographics, mechanisms of injury, details of injuries, angiographic findings, embolization techniques, and technical and clinical outcomes, including spleen salvage rates and pro-cedure-related complications, were examined.ResultsOf the 40 pediatric and adolescent patients with blunt splenic injury, 17 underwent SAE (42.53%). The clinical success rate was 88.2% (15/17). No cases of embolization-related complications or clinical failure were observed. Spleen salvage after SAE was achieved in all patients. In addition, no statistically significant differences were observed in clinical outcomes (clinical success and spleen salvage rates) between low-grade (World Society of Emergency Surgery [WSES] spleen trauma classification I or II) and high-grade (WSES classification III or IV) splenic injury groups.ConclusionSAE is a safe and feasible procedure, and is effective for successful spleen salvage of blunt splenic injuries in pediatric and adolescent patients.
