[Abdominal aortic injury in a child: seat-belt syndrome]

Traumatic injuries of the abdominal aorta are rare, especially in the pediatric population, but they must be sought when the clinical signs are associated with a severe traumatic context. We report the case of a 7-year-old child who presented with a partial transection of the abdominal aorta following a traffic accident. The optimal management is based on the detection of the less striking but suggestive clinical signs, such as a belt hematoma in the abdominal wall or a decreased pulse in the lower limbs, as well as a systematic precise X-ray examination, and an urgent surgical intervention. The risk is complete rupture, whose time of occurrence after the accident is unpredictable. The abdominal aorta is anatomically protected, so injury in children is traditionally associated with seat belt wear. Lesions are related to the shearing of the abdominal aorta between the spine and the seat belt.
