Spinal cord complications after thoracic aortic surgery: Long-term survival and functional status varies with deficit severity

Kaplan-Meier estimate for survival of patients after thoracic aneurysm and thoracoabdominal aneurysm repair stratified by all patients who presented spinal cord ischemia (SCI, dashed line) and those who did not (dotted line). P value determined by Mantel-Cox long-rank univariate analysis.

Kaplan-Meier estimate for survival of patients after thoracic aneurysm and thoracoabdominal aneurysm repair stratified by spinal cord ischemia deficit I (SCID I, dot-dash line) and SCID II and III (solid line). P value determined by Mantel-Cox long-rank univariate analysis.
