2. Fig 1
Number of segmental artery (SA) pairs sacrificed during thoracic or thoracoabdominal aortic aneurysm repair at each location, with the corresponding paraplegia rate. The extent of resection is disregarded. If sacrifice of a single segmental artery had been critical, a spike in spinal cord injury (SCI) rate at that level would have been anticipated.

Distribution of different perfusion techniques used for each Mount Sinai group (defined in detail in the text). (A) 100% stacked column. (B) Absolute number histogram. (CPBP = cardiopulmonary bypass; HCA = hypothermic circulatory arrest; LHBP = partial distal aortic perfusion with left heart bypass.)

4. Fig 3
Distribution of spinal cord ischemic events (n = 21) based on the extent and location of aortic resection. The x axis represents the proximal origin of resection, and the z axis shows the extent. The inset figure shows the expected paraplegia rates with 95% confidence interval based on the proposed four-group classification. (CI = confidence interval; SA = segmental artery.)

Comparison between era 1 (striped bars) and era 2 (black bars) patients (before and after introduction of routine motor-evoked potential monitoring) with respect to extent of aneurysms, categorized according to the Mount Sinai classification for assessing paraplegia risk.
