Transesophageal versus transcranial motor evoked potentials to monitor spinal cord ischemia Kazumasa Tsuda, MD, Norihiko Shiiya, MD, PhD, Daisuke Takahashi, MD, Kazuhiro Ohkura, MD, PhD, Katsushi Yamashita, MD, PhD, Yumi Kando, MD, Yoshifumi Arai, MD, PhD The Journal of Thoracic and Cardiovascular Surgery Volume 151, Issue 2, Pages 509-517 (February 2016) DOI: 10.1016/j.jtcvs.2015.08.120 Copyright © 2016 The American Association for Thoracic Surgery Terms and Conditions

Figure 1 Schematic drawing of the experimental model. Typical waveforms of myogenic MEPs from anal sphincters and hindlimbs without spinal cord ischemia are described together. TC, Transcranial; MEP, motor evoked potential; TE, transesophageal; Prox, proximal; BP, blood pressure; CCA, common carotid artery.

Figure 2 Change in the waveforms of hindlimb myogenic MEPs during and after thoracic aortic occlusion. Left: a dog in the 10-minute occlusion group. Middle: dog 5 that developed paraparesis. Right: dog 6 that developed spastic paraplegia. TE, Transesophageal; MEP, motor evoked potential; TC, transcranial.

Figure 3 Light micrographs of the lower thoracic spinal cord (A, C, E, hematoxylin–eosin, ×10) and anterior horn of the proximal lumbar spinal cord (B, D, F, hematoxylin–eosin, upper bank; ×100, lower bank; ×400). A and B were taken from dog 4, C and D were taken from dog 5, and E and F were taken from dog 6.
