Fig 1 Classification of thoracoabdominal aortic aneurysms. Extent I, distal to the left subclavian artery to above the renal arteries. Extent II, distal to the left subclavian artery to below the renal arteries; this is the most extensive type of aneurysm and the only extent that is still associated with risk of paraplegia, with the use of adjunct distal aortic perfusion, cerebrospinal fluid, and moderate hypothermia. Extent III, from the sixth intercostal space to below the renal arteries. Extent IV, from the twelfth intercostal space to the iliac bifurcation (total abdominal aortic aneurysm). Extent V, below the sixth intercostal space to just above the renal arteries.

Fig 4 Multiple logistic regression analysis according to risk of neurologic deficit (ND) and aortic cross-clamp time without adjunct use. Solid line represents extent II thoracoabdominal aortic aneurysm (TAAA), and the dashed line represents all other extents.
