Abstract
Blunt cerebrovascular injury (BCVI) management in children currently follows guidelines developed for adults, with limited data on their efficacy in the pediatric population. This study aimed to explore injury features in the pediatric population with BCVIs and compare the clinical manifestations, diagnosis, and treatment of pediatric and adult BCVIs.
A retrospective data analysis of BCVI patients was conducted using the PROspective Observational Vascular Injury Treatment (PROOVIT) registry, covering the period from 2013 to 2022. The clinical manifestation, treatment, and outcome were compared between the adult and pediatric populations (<18 years old).
This study included 38 pediatric and 1310 adult patients with BCVIs. Pediatric patients had a higher median AIS-head score (4 vs. 3, p<0.001) and a lower Glasgow Coma Scale (GCS) at admission (9 vs. 14, p=0.005). The two groups had no significant differences in Biffl grade injury distribution. Computed tomography angiography (CTA) was the primary diagnostic method used in both groups (78.9% in pediatrics and 87.8% in adults; p=0.084). Carotid artery injuries were the most frequently affected vessels in pediatric patients (71%), while vertebral artery injuries were more prevalent in adults (53.4%) (p<0.001). Treatment methods were similar, with most patients receiving medical treatment (68.4% in pediatrics vs. 77.4% in adults; p=0.264), although fewer pediatric patients continued medical therapy post-discharge (52.6% vs. 81.1%, p=0.031). The incidence of BCVI-related stroke was similar between groups (7.9% in pediatrics vs. 6.3% in adults; p=0.959). In-hospital mortality was not significantly different between the two cohorts, but hospital length of stay differed significantly, with pediatric patients having shorter stays than adults (p=0.047).
Our findings suggest that the current management patterns for BCVI in children are not significantly different from those in adults. This similarity may reflect the adoption of care strategies based on adult experience in the absence of pediatric-specific guidelines. Additionally, the outcomes in the pediatric population were comparable to those observed in adults, underscoring the potential effectiveness of these adapted approaches while highlighting the need for further research to develop age-specific guidelines for pediatric BCVI management.
•A higher AIS head was associated with a higher risk of BCVI in children.•The carotid artery was the most frequently injured vessel in pediatric patients.•Fewer pediatric patients were discharged on antithrombotic therapy compared to adults.
