Staged procedure to prevent major adverse events in extensive aortic aneurysm repair

Surgical management of extensive thoracoabdominal aortic aneurysms is associated with high rates of mortality and morbidity, including spinal cord ischemia. We report a successful three-stage repair combining open and endovascular surgery in a patient presenting with an ascending, arch, and thoracoabdominal aneurysm. Spinal cord protective measures included a staged approach, preserved antegrade flow to the left subclavian and hypogastric arteries, absence of aortic cross-clamping, and aggressive perioperative hemodynamic monitoring.
