Management of lower extremity vascular injuries in pediatric trauma patients: 20-year experience at a level 1 trauma center

Introduction Pediatric lower extremity vascular injuries (LEVI) are rare but can result in significant morbidity. We aimed to describe our experience with these injuries, including associated injury patterns, diagnostic and therapeutic challenges, and outcomes.Methods This was a retrospective review at a single level 1 trauma center from January 2000 to December 2019. Patients less than 18 years of age with LEVI were included. Demographics, injury patterns, clinical status at presentation, and intensive care unit (ICU) and hospital length of stay (LOS) were collected. Surgical data were extracted from patient charts.Results 4,929 pediatric trauma patients presented during the 20-year period, of which 53 patients (1.1%) sustained LEVI. The mean age of patients was 15 years (range 1-17 years), the majority were Black (68%), male (96%), and most injuries were from a gunshot wound (62%). The median Glasgow Coma Scale score was 15, and the median Injury Severity Score was 12. The most commonly injured arteries were the superficial femoral artery (28%) and popliteal artery (28%). Hard signs of vascular injury were observed in 72% of patients and 87% required operative exploration. There were 36 arterial injuries, 36% of which were repaired with a reverse saphenous vein graft and 36% were repaired with polytetrafluoroethylene graft. One patient required amputation. Median ICU LOS was three days and median hospital LOS was 15 days. There were four mortalities.Conclusion Pediatric LEVIs are rare and can result in significant morbidity. Surgical principles for pediatric vascular injuries are similar to those applied to adults, and this subset of patients can be safely managed in a tertiary specialized center.Level of evidence Level IV, retrospective study.
