Prevention of Spinal Cord Ischemia in an Ovine Model of Abdominal Aortic Aneurysm Treated With a Self-Expanding Stent-Graft

The use of an internal shunt during aneurysm creation and internal iliac-to-external iliac transposition prior to bifurcated stent-graft deployment prevented spinal ischemia in an ovine AAA model. Chronically deployed stent-grafts were well tolerated.
