Successful Open Thoracoabdominal Aortic Repair in a Patient with Severe Aorto-Iliac Occlusive Disease: A Rare Case Report

Open repair of thoracoabdominal aortic aneurysm (TAAA) in a patient with severe aorto-iliac occlusive disease is considered to cause an extremely high risk for spinal cord injury. A 71-year-old man who had previously undergone axillo-bifemoral bypass for aorto-iliac occlusive disease presented with persistent dilation of a TAAA. Using distal perfusion via partial extracorporeal circulation at mild hypothermia, we performed segmental sequential repair of Crawford type II TAAA. Various efforts were made to avoid spinal cord injury and ischemic visceral organ damage. Consequently, the patient completely recovered without any serious complications.
