Although endovascular treatment of aortic arch aneurysm is a recently induced procedure, only a few cases are indicated and outcomes are questionable.

OBJECTIVES The repair of extensive thoraco-abdominal aortic aneurysms (TAAAs) is invasive and carries a high risk for spinal cord injury (SCI). The aim of this study was to assess the early results and collateral circulation to the spinal cord after hybrid repair for Crawford extent II aortic aneurysms. METHODS Between 1997 and 2013, we performed 128(More)
