Endovascular Repair of Traumatic Infrarenal Aortic Injury in an 8-Year-Old

Abstract

The patient is an 8 year-old male presenting to outside facility following high-speed motor vehicle collision in which he was a restrained passenger. CT imaging at that time demonstrated a traumatic infrarenal aortic pseudoaneurysm, extensive pneumoperitoneum and free fluid, and an unstable L2 vertebral body fracture. He underwent exploratory laparotomy with small bowel resection prior to transfer. The patient was left in discontinuity and temporary closed. Vascular surgery was consulted upon arrival to tertiary care children’s hospital. The decision was made to proceed with emergent endovascular repair. An aortogram confirmed the location of the aortic disruption well below the renal arteries, superior to the bifurcation. An 11 mm × 5 cm Viabahn covered stent was placed across the injury with adequate proximal and distal seal. This is a case of seatbelt-related pediatric infrarenal aortic injury in the setting of polytrauma. Endovascular repair was pursued in this damage-control setting.
