Early interpretation of evoked potential and H-reflex in thoracoabdominal aortic replacement
Objective. To analyze intraoperative neurophysiological monitoring modalities (somatosensory evoked potentials, motor evoked potentials or H-reflex) as the earliest signs of spinal cord ischemia in open thoracoabdominal aortic replacement, and to evaluate contribution of each modality to the first alert signal.
