Abstract:
A patient with residual thoracoabdominal aortic aneurysm and chronic dissection extending into the branch iliac arteries underwent staged open and endovascular repair. Open repair of the reno-visceral segment was performed with an "elephant trunk" trunk graft placed distally into a 12-cm infra-renal aorta. One month later, the patient underwent a successful completion endovascular aortic repair. This case demonstrates the utility of combining traditional and endovascular surgery to manage complex aortic pathologies.
