Endovascular reconstruction of aortic bifurcation for aortic pseudoaneurysm in a pediatric trauma patient

Abstract

Endovascular treatment options for vascular injury in pediatric patients are quite limited owing to concerns regarding long-term durability and the lack of devices suitable for the pediatric anatomy. However, in rare circumstances, open surgical therapy will not be an option, and patients will require unconventional endovascular solutions for lifesaving or limb-saving therapies. In the present report, we describe an endovascular treatment of a pediatric patient for whom initial surgical management of a blunt abdominal aortic injury had failed, with subsequent development of an aortic pseudoaneurysm. A 10-year-old girl had presented after a high-speed motor vehicle accident with a seatbelt sign. Multiple abdominal injuries were identified, including blunt aortic injury, significant devitalization of the small bowel, colonic perforation with fecal contamination, multiple lumbar spine fractures, and pulmonary contusions. The patient developed bilateral lower extremity ischemia from the aortic injury and had initially undergone open repair. One month later, the patient had developed a pseudoaneurysm of the aorta near the aortic bifurcation. Because of the hostile abdomen and ensuing short gut syndrome, the pseudoaneurysm was managed using endovascular techniques. The limb of an Excluder internal iliac branch endoprosthesis (W.L. Gore & Associates, Flagstaff, AZ) was used as the endograft. The aortic bifurcation was raised and reconstructed using four Viabahn self-expanding stents (W.L. Gore & Associates). The completion angiogram showed complete resolution of the pseudoaneurysm. The follow-up computed tomography angiogram showed widely patent stent grafts with complete resolution of the pseudoaneurysm. Endovascular management of traumatic vascular injuries in pediatric patients is feasible. The likelihood of reintervention in the future is high with patient growth. However, it is a viable option in lifesaving or limb-saving situations in which open repair is high risk.
