Conditions

Aortic aneurysm, aortic dissection, aortic injury, etc.

Interventions

In addition to transcranial motor evoked potentials, transesophageal motor evoked potentials are monitored during aortic surgery using an equipment for neurophysiological measurements.

Eligibility

Sex/Gender
All

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

MeasureTime frame
Variation of the amplitude of motor evoked potentials before and after insertion of a transesophageal echo probe

Secondary

MeasureTime 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
