Eligibility
Inclusion criteria
Inclusion criteria: Patients undergoing elective aortic surgery with a risk of spinal cord ischemic injury who are to be monitored for transcranial motor evoked potentials in the ordinary course of medical treatment (aortic surgery mainly in the descending or thoracoabdominal aorta for aortic aneurysms, aortic dissection, aortic injury, etc.)
Exclusion criteria
Exclusion criteria: Patients undergoing emergent or urgent aortic surgery (within 24 hours of admission) Patients with abnormalities of the esophagus (tumors, varices, post-esophageal surgery, whigh degree compression deviation causing obstruction) Patients who are judged inappropriate by the principal investigator (or sub-investigator).
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Variation of the amplitude of motor evoked potentials before and after insertion of a transesophageal echo probe | — |
Secondary
| Measure | Time frame |
|---|---|
| Ease of insertion (subjective 5-point scale) Ratio of the amplitude of motor evoked potentials obtained by 150mA and 200mA stimulation Diagnostic accuracy of neurological poutcomes by the changes in motor evoked potentials during and at the conclusion of surgery Adverse events | — |
