An Event-based Communication Concept for Human Supervision of Autonomous Robot Teams

摘要

Blunt aortic injury is a serious condition with a high mortality rate. Although rare, blunt aortic injury associated with spinal fracture has also been reported, and appropriate management of aortic disease is key to a good outcome. This report is a case of a 78-year-old man who was found to have a transverse fracture (Chance fracture) in the ninth thoracic vertebra, with a sharp bone fragment compressing the thoracic aorta. Early spinal surgery was needed; however, there was concern about the possibility of bleeding from the aorta and surrounding small arteries associated with the bone fragment during spinal surgery. Therefore, thoracic endovascular aortic repair was performed before spinal surgery. The next day after thoracic endovascular aortic repair, posterior spinal instrumentation was performed, and the postoperative course was uneventful. Because aortic injury associated with vertebral fracture can lead to massive bleeding and spinal cord injury, endovascular repair before spinal surgery is reasonable.
